Short summary
We estimated the ammonia emissions based on the constant emission factors and those characterizing the agricultural processes for the Yangtze River Delta, China. The discrepancies between the two estimates and their causes were analyzed. Based on ground and satellite observations, the two estimates were evaluated with air quality modeling. This work indicates ways to improve the emission estimation and helps better understand the necessity of multi-pollutant control strategy.
