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.
