Ammonia phase PARtitioning and Transport-lite (APART-lite)
Ammonia (NH3) is receiving significant increased attention nationally (and internationally) because it is an unregulated air pollutant that contributes to fine particle formation and nitrogen deposition. However, our observations of the atmospheric sources, sinks, and phase partitioning of NH3 is limited compared to other major anthropogenic pollutants. In contrast to declining emissions of nitrogen oxides (NOx) from combustion sources, the emissions of NH3 from fertilizer applications and livestock production have grown in the U.S. Livestock are also large sources of CH4, a potent greenhouse gas.
This dataset includes test flight data used to track agriculturally impacted air masses in-situ using the University of Wyoming King Air (UWKA) research aircraft. The data was used in a funded NSF proposal to work in the Colorado Front Range since there are large emissions sources of NH3 and CH4 from concentrated animal feeding operations in northeastern Colorado.
