| Abstract: | By use of MODIS/Terra-Aqua daily snow cover products(MOD10A1,MYD10A1) and AMSR/Aqua daily snow water equivalent from October 1,2002 to March 31,2008 in Qinghai province,the ten-days composite algorithms of MODIS and AMSR-E data were studied,and the snow classification images of MOYD_10D,AE_10D and MDAE_10D were composed during the study period.The classification accuracies of the three kinds of images were analyzed using climate station data.The results showed that: 1) when the snow depth is more than 4 cm,... |
