THE SIMPLIFICATION OF OXYGEN-ABSORPTION COEFFICIENT FORMULA IN MICROWAVE BAND

中文摘要:

      研究氧分子在微波5mm附近的吸收系数,对于卫星和地面微波遥感大气温度,有重要的意义。为了迅速而准确地遥感大气温度层结,需要有一个简单而精确的吸收系数表达式。我们分别求出:在一定温度、压力范围内,5mm波段氧分子吸收系数近似表达式及标准等压面上5mm波段氧分子吸收系数与温度关系的近似表达式。以这些公式取代Meeks-Lilley公式,来提高遥感的时效。

英文摘要:

      Study of oxygen-absorption coefficient in 5mm wave band is important for remote sensing of atmospheric temperature profile from satellite or ground. In order to obtain the atmospheric profile speedly and accurately, it is necessary to have a simple formula of oxygen-absorption coefficient. In this paper, the oxygen-absorption coefficient formula in a certain range of temperature-pressure and the oxygen-absorption coefficient formula of the standard pressure surface have been derived. These formulae may substitute for Meek-Lilley formula in remote sensing of atmosphere.
