摘　　要：该文提出了利用ＴＯＶＳ的ＭＳＵ－１（微波辐射仪的第一通道、中心频率５０．３１ＧＨｚ）、ＨＩＲＳ／２－８（高分辨率红外辐射仪的第八通道、中心波长１１．１０μｍ）、ＨＩＲＳ／２－１９（中心波长３．７０μｍ）及ＨＩＲＳ／２－２０（中心波长０．７０μｍ）光谱特性的差异进行云的检测，以及在晴空条件下测雪的方法．该方法测出的１９９３年１月我国东部地区和１９９１年１月西藏高原东部地区降雪过程的积雪图，与实况相符．The methods of detecting cloud and monitoring snow cover in clean sky are put forward by using the spectral difference of MSU 1(Microwave radiometer CH1, the central frequency 50 31 GHz)、HIRS/2 8(High resolution infrared radiometer CH8, central wavelength 11 10 μm)、HIRS/2 19(central wavelength 3 70 μm) and HIRS/2 20(central wavelength 0 70 μm)of TOVS. The snow cover charts of the snow processes for eastern China in Jan. 1993 and the eastern Tibet Plateau in Jan. 1991 with the method mentioned above are in accord with the observational data.
