Abstract
The atmospheric transport and fate of ammonia (NH3) depend on both meteorological and chemical conditions once it
is emitted into the atmosphere. The largest source contributing to NH3 emission is the agricultural production, in
particular animal operation, in North Carolina (NC). In this study, three-dimensional numerical meteorological and air
quality models are applied to study the transport and fate of NH3 in the atmosphere in an area in southeast US centered
over NC. One summer and one winter month simulations with a 4-km horizontal grid were conducted to simulate the
meteorological and chemical environments for the transport and transformation of the reduced nitrogen, NHx
( NH3+NH4
