Multi-functional Transport Satellite-2（ MTSAT-2） geostationary satellite data is used to monitor snow cover over China. Moderate Resolution Imaging Spectroradiometer（ MODIS） snow cover products and station observations are used for comparison and validation. Angular correction and multi-temporal data combination are carried out first based on MTSAT-2 data characteristics. Snow cover algorithm is developed based on different indexes and thresholds. MODIS snow cover products are used to compare with MTSAT-2 snow cover images from January 1 to 31

2011. Station observations are used for the accuracy e valuation. From this work

it can be found that:（ 1） cloud-contamination percentage of MTSAT-2 snow cover is about 30%

while 60% for MODIS snow cover products during the period of January;（ 2） under clear-sky condition

the overall accuracy of M TSAT-2 and MODIS snow cover both reach higher than 92%. Under all-sky condition

overall accuracy of MTSAT-2 and M ODIS is about 65% and 35%

respectively;（ 3） monitoring snow cover using MTSAT-2 data can remove more cloud and obtain more information about the surface. This method can be used in monitoring snow cover China with high accuracy

which is significant to climate change research and disaster prevention.
