Researchers use satellite data to show vehicles are an under-recognized source of urban ammonia pollution

Green Car Congress

By disrupting normal societal activities such as driving, COVID-19 lockdowns afforded a unique opportunity to study their impacts on the environment. The researchers focused on western Los Angeles, where previous on-the-ground measurements found that vehicle emissions of NH 3 were being underestimated. 1c00730.

Satellite study suggests California clean air regulations working to reduce PM2.5 emissions in state

Green Car Congress

The open-access study, which focused on the four major components of PM 2.5 species, was recently published in the journal Atmospheric Environment. This study is the first attempt to use the Multi-angle Imaging SpectroRadiometer (MISR) aerosol sensors aboard NASA’s Terra satellite to predict PM 2.5 to predict PM 2.5

Study finds gasoline exhaust contributes more to formation of secondary organic aerosols than diesel

Green Car Congress

Contrary to expectations, exhaust from gasoline vehicles contributes more to the production of secondary organic aerosols (SOA) than exhaust from diesel vehicles, according to a new study by scientists from the Cooperative Institute for Research in Environmental Sciences (CIRES), NOAA’s Earth System Research Laboratory (ESRL) and other colleagues.
