In recent years the satellite monitoring capabilities in particular to derive maps of aerosol optical depth (AOD) have increased tremendously. There are many aerosol retrieval algorithms for different satellites and sensors. In 2005, a new algorithm for AOD retrieval by synergetic use of of Terra and Aqua MODIS data (SYNTAM) was proposed by Tang et al. With this algorithm, surface reflectance and AOD can be simultaneously retrieved. Now we attempt to provide multi-scale AOD, using SYNTAM algorithm. We calculated AODs at 10km, 1km, 500m and 100m spatial resolution from MODIS and HJ-1A/1B CCD (the China HJ-1A/1B of the Environment and Disasters Monitoring Microsatellite Constellation Charge-Coupled Device) data over East China on June 25, 2009. The retrieval results were compared to the result of ground-based aerosol measurements by CE318 automatic sun tracking photometer at the AErosol RObotic NETwork (AERONET) sites. The validation results show that the results retrieved by SYNTAM have good precision.
