Our Series B: An Investment in Clean Air for All

By Aclima on November 19 2020

By Davida Herzl, Co-founder and CEO, Aclima

Ten years ago, I moved to Silicon Valley to start building Aclima, inspired by the stories of mission-driven and brilliant people coming together to solve the world’s hardest problems. Legendary companies like Fairchild Semiconductor and Xerox Parc, responsible for technology advancements that moved society forward by leaps and bounds, spoke to what was possible. I couldn’t imagine a more important problem than climate change. And I was convinced that the technology community had a big role to play in giving people the tools to understand and reduce emissions and their impacts on both human and planetary health.

PM 2.5 Surges As Wildfires Rage in California

By Aclima on September 21 2020

As six of the largest 20 fires in California history poured smoke into the atmosphere in recent weeks, and new fires were sparked in Oregon and Washington, the skies over the Bay Area and beyond were blanketed in smoke and at times turned unnerving shades of orange. Reports of ash falling flooded social media as entire towns were evacuated due to the fires.

California Air Quality During Lightning Complex Fires

By Aclima on August 28 2020

On August 16, 2020, more than 10,000 lightning strikes pummeled the Bay Area, sparking wildfires across the region. Twelve days later, two of the three largest fires ever recorded in California history are still burning. Aclima scientists analyzed both regulatory and Aclima data to identify patterns in the impacts of these lightning complex fires on air quality.

Where There’s Smoke in San Francisco, There’s Fine Particulate Matter in West Oakland

By Aclima on July 30 2020

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.

New Research Reveals Hyperlocal Air Pollution Varies Over Space & Time

By Aclima on June 30 2020

Scientists from the U.S. Environmental Protection Agency (EPA), the Electric Power Research Institute (EPRI), Envair, and Aclima analyzed millions of block-by-block measurements (2016–2017) of air quality in Los Angeles, the San Francisco Bay Area, and California’s Central Valley with Aclima sensing technology on Google Street View cars, and confirmed that air pollution can persistently vary by six to eight times from one block to another.

Mapping Street-Level and Real-Time Air Quality in West Oakland

By Aclima on June 11 2020

Today, in collaboration with local community groups West Oakland Environmental Indicators Project (WOEIP) and Rising Sun Center for Opportunity, we are launching a freely available, interactive, online report of block-by-block air pollutant and greenhouse gas levels throughout West Oakland, representing 34 million data points measured over six months in the second half of 2019. Community members can look up hyperlocal air pollution by address — where they live, work, play, and learn — share on social media, and access resources to take action.

Air Pollution Fluctuates in San Diego

By Aclima on May 28 2020

In February and March, physical distancing initiatives to slow the spread of COVID-19 resulted in reduced travel, which correlated with declines in air pollutant levels around the world. In April, however, we began to see an increase in air pollutants in parts of California, as measured by both regulatory monitors and Aclima’s mobile sensing network.

Cleaner Air Throughout California

By Aclima on April 14 2020

Californians have now been sheltering in place since March 20. While social distancing is slowing the spread of COVID-19, it’s also significantly reducing air pollutant and greenhouse gas levels across the state. Residents from San Diego to Sacramento are seeing clearer skies and breathing cleaner air, even in the center of cities that rarely experience a noticeable reduction in air pollution.

Bay Area Pollutant Levels Drop for Second Week

By Aclima on March 31 2020

With the shelter-in-place order in the San Francisco Bay Area extending until at least May 1, millions of people continue to stay home to slow the spread of COVID-19. Just two weeks into what is now expected to last at least six weeks, there are indications that social distancing is indeed flattening the curve and slowing an influx of patients that might otherwise have overwhelmed Bay Area hospitals.

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.
