%X To speed up the computation of the retrieval of Aerosol Optical Depth (AOD), a cyclic partition and collective communication strategy based on serial computation algorithm of Synergy of TERRA/MODIS and AQUA/MODIS (SYNTAM) was proposed to archive parallel computation of AOD retrieval from the both Moderate Resolution Imaging Spectroradiometer (MODIS) satellite (TERRA, AQUA) data by message passing on the IBM cluster 1600 high performance compute of Chinese Meteorological Administration. Experimental results demonstrate that the parallel SYNTAM can decrease computation time greatly. Compared with measurements from ground-based sun-photometers, the relative error of experiment results from the parallel SYNTAM is less than 22% in call cases, indicating that it can meet the needs of high accuracy such as air quality monitoring.
