Abstract： With Gurbantunggut desert as the study area and by using moderate resolution imaging spectrometer (MODIS) data, which is a kind of optical remote sensing data，in combination with snow reflectance spectra simultaneously measured by ASD Field Spec, the authors evaluated the correction capability of FLAASH model. Some results have been attained: ① Snow reflectance from 1st to 7th band of MODIS is similar to the simultaneously measured snow reflectivity，and the correlation coefficient of all bands is 0.82 on the whole， indicating that FLAASH can greatly enhance the capability for identifing surface features of M0DIS . ② On the basis of linear relationship between snow reflectance after correction at MODIS channel 6 and NDSI and measured snow density, a snow density remote computation model can be built by way of regression and fitting.
