Abstract	We carried out measurement of spectral reflectance for various ground covers in the Mongolian highland in the summer of 1994 and calculated the normalized difference in vegetation index (GT-NDVI). The GT-NDVIs were compared with the NDVI derived from AVHRR data (NOAA-NDVI). It was found that there are intrinsic differences between GT-NDVI and NOAA-NDVI such as NOAA-NDVIs always showed lower values than GT-NDVIs. Then correction algorithms for atmospheric effects were applied to the NOAA-NDVI by taking into account solar zenith angle, scan angle and elevation. In the corrected NDVI(COR-NDVI), the values increased to correspond with those of GT-NDVI. --author's abstract
