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

Green Car Congress

Researchers now report in ACS’ Environmental Science & Technology Letters that satellite data from before and during the spring 2020 lockdown in Los Angeles shows that vehicles, rather than agriculture, are the main source of urban airborne ammonia (NH 3 ), which forms small particles that contribute to air pollution and harm human health.
