TES ammonia over farming regions

CAMNET (in-situ surface measurements) and TES retrievals show consistent dependence on concentration of livestock facilities

Ammonia over North Carolina

number of livestock facilities within 10 km
  • Characterizing emissions is important for understanding secondary aerosol formation and the global nitrogen budget.
  • Animal agriculture accounts for 50-85% of man-made ammonia volatilization in the US.
  • The Chesapeake Bay is likely receiving ammonia deposition from upwind areas with intensive agricultural such as N. Carolina.
  • Ammonia concentrations have large spatial variability: TES can capture this variability
