Global and Regional Aerosol Variations During the EOS Satellite Era: An Analysis Using Data From Multiple Satellite Sensors and a Global Model

Dr. Mian Chin
Atmospheric Chemistry and Dynamics Branch

We present here a global model (GOCART) analysis of variations of atmospheric aerosols from 2000 to 2007 using data from satellite sensors of MODIS, MISR, AVHRR, and CALIPSO lidar, and from ground-based sunphotometer network AERONET. We compare the model results with observations over 7 land and 7 ocean regions that are dominated by different aerosol types from anthropogenic, dust, biomass burning, and transported aerosols. We will analyze the observed change of aerosols in terms of change of emission, transport, and other factors, examine the relationships between emission, aerosol mass loading, aerosol optical depth, and radiative effects, and try to explain the differences in satellite retrieved aerosol optical depth from different sensors during the 8-year time period.
