NASA researchers mapped ammonia emissions in California's Imperial Valley, highlighting health risks from airborne particulate pollution. This study aids in tracking and managing air quality.

NASA's Jet Propulsion Laboratory, in collaboration with the Aerospace Corporation, conducted a study to map ammonia emissions in California's Imperial Valley. Using airborne imaging spectrometers, researchers identified ammonia plumes from agricultural activities and geothermal processes. Ammonia is a precursor to fine particulate matter, which poses health risks when inhaled. The study revealed that ammonia levels in the Imperial Valley were significantly higher than in nearby areas. This research aims to enhance monitoring of ammonia emissions, which are often overlooked, and to inform air quality management strategies. The findings will help regulatory bodies prioritize sources of pollution and improve public health outcomes in affected communities.
