Abstract
Accurate estimates of ammonia (NH3) emissions are needed for reliable predictions of fine particulate matter (PM2.5) by
air quality models (AQMs), but the current estimates contain large uncertainties in the temporal and spatial distributions
of NH3 emissions. In this study, the US EPA Community Multiscale Air Quality (CMAQ) modeling system is applied to
study the contributions of the agriculture≠livestock NH3 (AL-NH3) emissions to the concentration of PM2.5 and the
uncertainties in the total amount and the temporal variations of NH3 emissions and their impact on the formation of PM2.5
for August and December 2002.
The sensitivity simulation results show that AL-NH3 emissions contribute significantly to the concentration of PM2.5,
