This paper presents a software system

MODISoft

which can process MODIS 1B data automatically to generate various products covering the whole China.Some new algorithms were proposed to overcome the shortcomings of NASA MODIS standard products.The strength of the LAI retrieval method is that it avoids using two incompatible methods in NASA LAI product.The algorithm for estimating both land surface reflectance and aerosol optical depth is based on mutli-temporal observations and produces more accurate products.The cloud mask algorithm detects low clouds better.Some of key inputs for these algorithms are localized over China.This system also produces some new products that are not available in the standard NASA product suite

including the forest burned scar and PAR.The data processing system is operationally run in the National Scientific Data Center for Resources and Environment

Chinese Academy of Sciences.
