Abstract: We have developed a software system, MODISoft®, to process automatically global 1B level data for MODIS, AVHRR, VIIRS and Landsat TM to generate various products. Some new algorithms were proposed to overcome the shortcomings of current products. The LAI retrieval method can seamlessly connect AVHRR and MODIS to generate a long-term consistent LAI product. The algorithm based on the mutli-temporal observations has been proposed to estimate more accurate aerosol optical depth. The cloud mask algorithm performs better in detecting low clouds. Several products have been distributed in the Scientific Data Center for Resources and Environment, Chinese Academy of Sciences.
