Nitrogen isotopes reveal high NO emissions from arid agricultural soils in the Salton Sea Air Basin.

Air quality management commonly aims to mitigate nitrogen oxide (NO) emissions from combustion, reducing ozone (O) and particulate matter (PM) pollution. Despite such ongoing efforts, regulations have recently proven ineffective in rural areas like the Salton Sea Air Basin of Southern California, which routinely violates O and PM air quality standards. With over $2 billion in annual agricultural sales and low population density, air quality in the region is likely influenced by the year-round farming activity.
