Agriculture + Air Quality
We must understand the impact of industrialization on the environment and how people develop land for their use as human population grows. Agriculture and air quality are both vital to human prosperity, determining what we eat and what we breathe, but their many interactions are often poorly understood. My work explores the characterization of agricultural ammonia emissions and quantification of air quality impacts on global crop production.
Data, Tools, and Methods
Aircraft and surface network gas and aerosol concentration measurements (e.g., CalNex campaign, AMoN)
Ammonia column satellite measurements (IASI)
United States EPA emission inventories
Empirical ammonia emissions derived from livestock population and micrometeorology
Global and United States crop production data
