Dear teachers, I used CMAQ5.2 to simulate the emission of ozone pollutants in China twice, using the emission sources of the five departments (Industry, agriculture, transportation, electricity and residential ) in the MEIC list and only the agricultural sources in the MEIC list. The spatial distribution of the two simulation results on June 1, 2020 is as follows, and the ozone simulation is consistent.
Would like to ask you why this result? Only NH3 emissions from agricultural sources, VOC, NOX and other emissions are 0, and it is reasonable to say that the ozone concentration of only agricultural sources should be extremely low.
Spatial distribution of ozone simulated by five sectors:
Only agricultural sources simulate the spatial distribution of ozone:
