Simulation of Impact of Different Pollutant Observation Information on Assimilated Emission of CMAQ
不同大气污染物监测密度对CMAQ源同化修正效果影响的模拟

Assimilated emissions with different spatial scales are retrieved using a nudging-based inverse modeling approach coupled with CMAQ model based on the observed data of SO2 and NO2 concentrations with four different resolutions over China. The scale impact characteristics of space resolution of observation stations at which SO2 and NO2 concentration are sampled on correction effect of a nudging-based inverse model and the level of air quality forecasts was simulated by WRF and CMAQ model. The important effec...
