New Research Shows Racial and Ethnic Disparities in Hyperlocal Air Pollution

By Aclima on September 9 2021

Peer-Reviewed Study Drawing on Data from Aclima Mobile Measurements Published in PNAS Reflects the Lived Experience of Communities of Color in the Bay Area.
A new peer-reviewed hyperlocal air pollution study with implications for environmental justice policy has been published in the Proceedings of the National Academy of Sciences (PNAS). The study was led by Dr. Sarah Chambliss in the Department of Civil, Architectural and Environmental Engineering at the University of Texas at Austin and Prof. Joshua Apte from UC Berkeley, with co-authors from the ​​National Institute of Environmental Health Sciences, Carnegie Mellon University, University of Washington, and Aclima.

The scientific study funded by the US EPA, EDF, and Health Effects Institute examines how the variability in ambient air pollutant levels at local and regional scales correlates with the racial and ethnic demographics of the people who live within and across four counties in the San Francisco Bay Area. The hyperlocal air pollution data for the study was generated by the Google Street View fleet equipped with the Aclima hyperlocal air mapping platform.

All of the air pollutants measured —black carbon (BC), nitric oxide (NO), nitrogen dioxide (NO2), and ultrafine particles (UFP) —had meaningful variation at hyperlocal (i.e. a city block), local (i.e., within individual neighborhoods) and regional (i.e., between neighborhoods) scales.

This variability of air pollution results in racial and ethnic disparities in exposure. For Hispanic and Black populations, median concentrations of UFP, NO, and NO2 were 8%-30% higher than the population average.

Early Tuesday morning in San Francisco, a massive five-alarm fire erupted in a building supply company according to the San Francisco Fire Department (SFFD). Smoke from the fire rose in a plume high above ground level and was blown northeastward by the winds aloft. Aclima’s network of mobile and stationary air quality sensors picked up the local spikes in fine particulate matter (PM₂.₅) in the hours after the fire began. We continued to see elevated PM₂.₅ levels — particularly in the East Bay — until the valiant and commendable people of the SFFD all but extinguished it midday. However, firefighters remain on the scene as the debris continues to burn.

Bay Area Air Pollution During COVID-19

By Aclima on March 24 2020

How efforts to flatten the curve of COVID-19 are reflected in air quality

With millions of people sheltering in place across the Bay Area, the daily ebb and flow of urban life has come to a sudden halt. The COVID-19 pandemic has upended many patterns and placed tremendous strain on medical, economic, political, and social systems. The corresponding drop in regional traffic, along with reduced industrial and commercial activity, has also led to a significant decline in air-polluting emissions. While images of empty freeways paint a surreal picture, they also give us an unprecedented glimpse into what happens to the air we breathe when we drastically and suddenly cut emissions.

Meet the Maker: Brian LaFranchi, Technical Operations Manager

By Aclima on November 6 2017

Much of Project Air View’s success owes great credit to the years of work our late colleague, Chris McMahon, dedicated to this campaign. Chris was instrumental in developing the Aclima hardware platform and in managing the work in the field. We are forever grateful to Chris for the time and expertise he shared with us.

What do you do at Aclima?

I manage our Google Street View cars and drivers. I do a variety of things including designing drive plans, overseeing the general health of our equipment in the vehicles, and some testing and data analysis along the way. I also ensure that we maintain good data quality, which is something my training as an analytical chemist has prepared me for.

How do the Google Street View drivers know where to go?

In most cases, we assign them what we call ‘polygons’, which are essentially shapes drawn over a particular neighborhood on a map. They can see their position in real time within the polygon on the Google Street View monitor and are instructed to drive every segment of road in that polygon.

What inspires you about our mobile mapping project?

Being able to visualize air pollution data at a fine scale is what led me to seek out Aclima, and it is what keeps me inspired every day. The challenge in making environmental quality measurements is that we have been “tool limited” for a long time. Aclima powers past many of these limitations. Visualizing very large spatio-temporal datasets is one particular challenge that we have overcome and being able to easily browse the data on a map is something that excites and inspires me.

What do you hope people get out of the data we’re collecting about outdoor air?

This field has been tool limited, but also data point limited — in that the sheer number of areas aren’t monitored. The atmosphere is a very dynamic system. By having mobile measurements, you can understand how pollutants are behaving in time and space. Ultimately, I hope that our data leads to meaningful change. If we can put data in the hands of community leaders, you can start to imagine what good they can accomplish.

What challenges did you face to get this project off the ground?

There are many challenges with a project of this size. One small but important aspect, for example, is vehicle maintenance. We put our hands on every car, and the equipment inside, every day — from regular calibrations to daily inspections. We’ve had a few breakdowns, tires changes, and many dead car batteries along the way.

What are you most proud of working at Aclima?

90% of my job is making sure that the data comes in and is good quality. When I see the data displayed on one of our maps, I’m proud knowing that I contributed and that the data is trustworthy.

Where do you hope we drive next?

I’d like to drive the southern San Joaquin Valley — cities like Fresno and Bakersfield — which is an area that suffers from some of the worst air quality in the country. Also the Yosemite Valley, which has obvious appeal, but also has tons of traffic throughout the summer months, can be impacted by wildfires, and, to top it off, receives pollution transported from the Central Valley. Internationally, it would be really interesting to measure and monitor air quality in Mexico City, which has historically bad air quality and is located in high altitude, which makes it a unique place to study.

Where Agriculture, Geography, and Climate Affect the Air

By Aclima on November 6 2017


California’s Central Valley is often referred to as America’s Breadbasket, famously depicted in John Steinbeck’s Grapes of Wrath. Nearly 50% of U.S.-grown fruits, nuts, and vegetables are produced in California, in farms located in the Central Valley. Like dairy farms, the fields where alfalfa, rice, and strawberries are grown and harvested takes acres of space, seasonal tilling, and care. An output of this abundance combined with geography and weather, results in air pollution that is different from that typically found in urban areas.

The Science Behind Summer Air with Aclima Chief Scientist, Melissa Lunden

By Aclima on July 13 2016

In the classic song “In the Summertime,” Mungo Jerry sings: In the summertime when the weather is hot / You can stretch right up and touch the sky. The lyric elicits the familiar feeling of summer, a sensation of heat-induced laziness where you might stretch your arms up to the sky and let out a sigh. Yet the bright blue skies and warm weather that we associate with summer also come with heightened exposure to air pollution.

When Air Pollution Gets Personal

By Aclima on June 22 2016

Years ago, I spent several months in India at the Kumbh Mela in Allahabad. While I had heard of travellers succumbing to the food or water-induced “Delhi Belly”, I was struck by a persistent cough and respiratory infection that grew deeper and more irritating with each day spent at the dusty, smoke-filled festival. Hundreds of thousands of wood fire pits and stoves were used to cook, heat and worship during this annual event. In fact, millions of people at the festival were inhaling the extremely polluted air affecting me — and most Indians live and breathe this pollution every day of their lives.

Building Health and Wellbeing into the Office Environment

By Aclima on May 16 2016

When we think of our homes and office buildings, we think about structures that provide shelter and spaces to eat, sleep, and do our work. At a minimum, we hope that the buildings in which we spend 90% of our time don’t make us unhealthy. But what if buildings could actually provide us with information that would improve our wellbeing and increase our productivity?

How Environmental Sensor Networks Connect the Dots for Healthier Buildings

By Aclima on May 2 2016

From central air to green roofs, buildings serve as signs of the cultural times and showcases for technologies of the day. In the early nineties, the “green” building movement was brought into the public eye to reduce stress on the environment by encouraging low-impact, resource-efficient buildings. With high-profile help from organizations like the United States Green Build Council (USGBC) and its LEEDⓇ certification program, planetary health has benefited from these efforts by institutionalizing waste diversion from landfills and reducing energy use and the associated greenhouse gas emissions.

The Circular Economy: Don’t Waste This Opportunity

By Aclima on April 13 2016

Waste is pervasive in our society. The U.S. Environmental Protection Agency estimates that the average person generates 4.3 pounds of waste per day. In the U.S., more than 110 million tons of waste generated each year end up in over 3,500 landfills. The rest of it finds its way into our local waterways. Some of it ends up in the Great Pacific garbage patch, one of seven massive trash gyres floating in the world’s oceans.

Understanding Aclima’s Air Quality

By Aclima on March 28 2016

Do you work in a “green” or a “conventional” workplace? Buildings span a broad continuum, from modern LEED® Platinum-certified skyscrapers, to those built before germs or bacteria were even discovered. While the daily use and energy consumption across this wide range of buildings may be well known, the conditions we can’t see within their rooms and corridors are poorly understood despite their drastic effects on our health and wellbeing. Given that we spend 90% of our lives indoors, the conditions in our built environments have shown to be critical to health, happiness, and job performance. In short, indoor environmental quality matters and the more we know about it, the more we know about our own health and wellbeing.

Aclima and Google Partner to Map Outdoor Air Quality with Street View Vehicles

By Aclima on July 27 2015

U.S. Environmental Protection Agency Advised Aclima on Platform Test in Denver

SAN FRANCISCO (July 28, 2015) — Aclima, Inc., a San Francisco-based company that designs and deploys environmental sensor networks, today announced a new partnership with Google Earth Outreach to map and better understand urban air quality. The partnership enables a paradigm-shift in environmental awareness by equipping Street View cars with Aclima’s mobile sensing platform to see the air around us in ways never before possible. Three Street View cars took measurements of nitrogen dioxide, nitric oxide, ozone, carbon monoxide, carbon dioxide, methane, black carbon, particulate matter, and Volatile Organic Compounds (VOCs) — air pollutants which can affect human health or climate change.

“We have a profound opportunity to understand how cities live and breathe in an entirely new way by integrating Aclima’s mobile sensing platform with Google Maps and Street View cars,” said Davida Herzl, co-founder and CEO of Aclima. “With more than half of the world’s population now living in cities, environmental health is becoming increasingly important to quality of life. Today we’re announcing the success of our integration test with Google, which lays the foundation for generating high resolution maps of air quality in cities.”

Aclima instrumented three Google Street View vehicles to perform a month-long system test in the Denver metro area during the DISCOVER-AQ study conducted by NASA and the U.S. Environmental Protection Agency (EPA). The cars clocked 750 hours of drive time and gathered 150 million data points, correlated with data from EPA stationary measurement sites. EPA provided scientific expertise in study design and instrument operations as part of a Cooperative Research and Development Agreement (CRADA) with Aclima.

“Environmental air quality is an issue that affects everyone, especially those living in big cities,” said Karin Tuxen-Bettman, Program Manager for Google Earth Outreach. “This partnership with Aclima builds on our ongoing partnership with the Environmental Defense Fund, enabling us to take the next steps in our pilot project to use Street View and Google Maps as an environmental mapping platform. We hope this information will enable more people to be aware of how our cities live and breathe, and join the dialog on how to make improvements to air quality.”

To assess if air quality is meeting — or exceeding — public health standards, the EPA relies on an extensive network of stationary equipment, placed in urban areas, that measure carbon monoxide, nitrogen dioxide, sulfur dioxide, particulate matter, hydrocarbons and photochemical oxidants. The monitoring network is designed for air quality regulation, but does not give a detailed picture of a community or urban area such that people can get a real sense of what air pollution is in their immediate surroundings. Aclima’s mobile sensing platform on Street View cars complements EPA’s regional air measurement network by introducing a new body of knowledge about air quality at the street level.

“Our research partnership with Aclima is helping us understand air pollutants at the local and community level, and how they move in an urban area at the ground level,” said Dan Costa, Sc.D., National Program Director, EPA’s Office of Research and Development. “New mobile air measurements can complement existing stationary measurements for a more detailed picture of personal and community air quality.”

“The Denver pilot was a scientifically driven process to validate the use of Aclima’s system for mobile environmental sensing with Google Street View vehicles and proved that mobile sensing at the street level is possible,” said Melissa Lunden, Director of Research for Aclima. “We want to get this right. Which is why we asked a team of nationally recognized air and climate scientists to review our methodology.”

“Many things affect air quality — everything from our transportation and energy choices, to green space and the weather,” said Herzl. “Understanding these complex relationships is critical to managing and improving air quality. The Denver test prepares us for scaling the system and introducing Aclima’s mobile sensing platform to communities anywhere Google Street View vehicles drive. There’s unlimited potential for our work to help improve the health and resilience of communities everywhere.”

This Fall, Aclima and Google will expand mapping efforts to the San Francisco Bay Area and work with communities and scientists to explore applications for this new environmental tool.

Today’s announcement builds on Aclima’s established partnership with Google to map the indoor environment. Together, they have created a network that is the first of its kind — connected across 21 Google offices around the world. The system processes 500,000,000 data points each day on indoor environmental quality, including comfort measures of temperature, humidity, noise, and light, and air pollutants like carbon dioxide and particulate matter. The information allows Google to evaluate environmental factors in their offices and, in the future, make better decisions on workplace design to support employee wellbeing, productivity and creativity.

Aclima Comes Out of Stealth, Announces Partnerships with Google, EPA, and Lawrence Berkeley National Labs

By Aclima on June 29 2015

Partnerships advance Aclima Sensory Science™, making environmental quality visible through distributed sensor networks

SAN FRANCISCO (June 30, 2015)
 — Aclima Inc., a San Francisco-based company that designs and deploys environmental sensor networks, today unveiled its work and announced partnerships with Google Inc., the U.S. Environmental Protection Agency (EPA), and Lawrence Berkeley National Laboratory. Additionally, the company named an advisory board of luminaries to guide Aclima’s mission-driven work.

“We’re on a big, ambitious mission at Aclima to usher in an age of environmental awareness that creates a more resilient, healthy and thriving world,” said Davida Herzl, co-founder and CEO of Aclima. “There is a growing need — for businesses, governments and citizens alike — to ‘Live Aware’ by first understanding, and then improving our built and natural environments. Aclima has spent years in stealth creating a complete system to map environmental quality in an entirely new way, enabling us to see how our buildings, communities and cities live and breathe.”

To achieve its mission, Aclima’s team of designers, engineers and scientists built a full-stack hardware and software platform for measuring and understanding environmental quality in real-time. Aclima’s modular and scalable networks of internet-connected sensors generate billions of data points across a range of environmental factors. Each sensor network is customized to meet the needs of enterprise and government partners — whether a partner is interested in mapping greenhouse gases across an entire city, or air pollutants that affect human health inside commercial buildings.

The company’s cloud-based back-end and modular front-end tools process, analyze, and visualize limitless amounts of environmental data, enabling Aclima scientists and partners to discover real-time and long-term insights. With its managed infrastructure tools, Aclima ensures network reliability and optimal data quality. Aclima works hand-in-hand with partners to explore their spaces and apply insights toward optimal decision making. Aclima refers to this unique service model, combining technology and data-driven insights, as Sensory ScienceTM.

One of Aclima’s most significant enterprise partners to date is Google. For several years, Google and Aclima have worked together to deploy a global indoor environmental sensor network — the first of its kind — connected across 21 Google offices around the world. Five hundred networked Aclima devices currently process 500,000,000 data points each day on indoor environmental quality, including comfort measures of temperature, humidity, noise, and light, and emissions like carbon dioxide and particulate matter. The information allows Google to evaluate environmental factors in their offices and, in the future, make better decisions on workplace design to support employee wellbeing, productivity and creativity.

“Working with Aclima has helped us to bring together the best thinking, science, and technology to support Googlers in a new and innovative way,” said Anthony Ravitz from Google Real Estate and Workplace Services. “We strive to create the healthiest and best possible work environments for Googlers. Our vision is to create buildings that seamlessly support the people who inhabit them. Using Aclima’s science-driven sensor networks to map our indoor environmental quality is a big part of making that happen.”

To push the limits of current sensing technology, Aclima has established scientific and research relationships of the highest caliber. In 2013, Aclima and the EPA signed a Cooperative Research and Development Agreement (CRADA). The collaboration brings together EPA scientists with Aclima’s Research and Development team to improve data quality from small-scale sensors. The partnership is advancing Aclima’s measurement methods for its stationary and vehicular sensing platforms.

“With increasing public awareness and concern about air quality in communities, there’s an urgent call for publicly accessible local environmental data and air quality information, both indoors and outdoors,” said Dan Costa, National Program Director for Air, Climate, and Energy Program at EPA. “We’re excited to partner with Aclima to develop new sensor technologies and to conduct research that will provide more accessible, less expensive and more reliable data on air pollutants needed by decision makers in the public and private sectors to better understand the air we breathe.”

Aclima also leads a cross-sector collaboration with Lawrence Berkeley National Lab, UC Berkeley, University of Illinois at Chicago, and the EPA to engineer and commercialize a miniaturized particulate matter sensor — the smallest sensor of its kind — for the air pollutant most responsible for respiratory health problems, like asthma.

“Bringing a small-scale sensor of this type to market will help us to effectively measure particle pollution, which has been linked to a wide range of serious health problems,” said Dr. Lara Gundel, Staff Scientist at Berkeley Lab. “At Berkeley Lab we have been at the forefront of environmental sensing research, and our partnership with Aclima will bring this innovation out of the lab and into the market.”

Aclima began its startup journey with a belief that businesses can become market leaders by driving beneficial social change. Rather than focusing on a ‘minimum viable product’, Aclima’s founders sought a growth and partnership approach aimed at achieving ‘maximum societal impact.’ This approach supports the company’s ultimate vision of a real-time, dynamic, global layer of dense environmental data that gives society the tools to optimize human and planetary health.

“Understanding the link between planetary health and human health has never been more pressing,” said Herzl. “Aclima is working to make this invisible connection visible, on a grand scale and across industries. Having bootstrapped the company with revenue, grounded in strong business fundamentals, we’re excited to start sharing our work with the world. It is an honor to have Google, EPA, LBNL and our incredible advisory board working with us. The potential represented by this group is truly inspiring.”

Aclima Advisory Board members include luminaries such as: Jane Lubchenco, former Administrator of The National Oceanic and Atmospheric Administration (NOAA) under President Barack Obama; William K. Reilly, former Administrator of the EPA and Senior Advisor to TPG Capital; Peter Senge, Senior Lecturer at MIT School of Management, pioneer in systems science and author of “The Fifth Discipline”; Elad Gil, Serial entrepreneur and former VP of Corporate Strategy for Twitter; Greg Niemeyer, Professor at UC Berkeley and Director of the Berkeley Center for New Media; David Sherman, co-author of the “Flourishing Enterprise” and distinguished fellow at the Fowler Center for Sustainable Value; and Martin Goebel, Founder of Sustainable Northwest and former country president for World Wildlife Fund and Conservation International.
