Air-surface exchange

Air Surface Exchange:

CSER works to better understand how gases and particles move between the Earth’s surface and the atmosphere—an important process that affects the air we breathe. Our scientists focus especially on reactive nitrogen compounds, such as nitrogen oxides (NOₓ) and ammonia (NH₃), which play major roles in air pollution and can impact ecosystems when they return to the surface. Because these exchanges are difficult to measure and predict, CSER combines advanced computer modeling with field measurements across the United States. By collaborating with universities and federal partners, we help improve estimates of how these exchanges influence local air quality and how pollutants are removed from the atmosphere.
