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.
