Research Abstract

Chemical transport models (CTMs) of CMAQ and GEOS-CHEM wre used to study the source-receptor analysis based on Higher Direct-Decouple Method-3D (HDDM) and modeled green function optimization method to optimize the emission strength and initial condition of CTM. Source-receptor analysis and emissioninversion based on satellite trace gas observation and HDDM was used to study the impact of Chinese air pollutant emission to downwind countries. MOPITTO CO observation and green function optimization was used to estimate the year-by-year variation ofChinese CO emission intensity.
