ESTIMATION OF SOLAR DIRECT AND SCATTERING RADIATIONS IN A CLEAR SKY ATMOSPHERE FROM SATELLITE DATA

摘要

摘要: 根据光的多次散射理论,对水汽、气溶胶、臭氧、混合气体等实行辐射参数化处理;利用中国探空站资料和诺阿(NOAA)气象卫星垂直业务探测器(TOVS)资料反演的探空资料,由离散纵标法计算了大气各高度上的太阳直接辐射和散射辐射,并与此同时的和同站点位置的卫星可见光、红外测值进行统计回归拟合,建立卫星测值与大气中太阳直接辐射和散射辐射的计算模式,据此可以利用卫星资料估算太阳直接辐射和太阳散射辐射,这对于大气环境光学特性和大气环流、气候变化的研究有重要意义.

Abstract: Based on the multiple scattering theory,the radiative effect of moisture,aerosols,ozone and mixing gases is parameterized,and the Chinese sounding data and the NOAA TOVS retrieval data are used to calculate the solar direct and scattering radiations at each level in the atmosphere in terms of the discrete ordinate method.Meanwhile,the calculated radiations are statistically fitted with satellite visible and infrared radiation observations,thus developing a model for calculating the solar direct and scattering radiations from satellite observations in atmosphere.The solar radiations are of importance in atmospheric optic environment characteristics and the general circulation and climatic change researches.
