摘要
地表净辐射为地气系统净辐射与大气层净辐射之差。对大气层净辐射作不同的假定,可将地表净辐射与大气顶辐射收支之间的关系表示成不同的形式。本文利用1982年8月—1983年7月青藏高原地区地面辐射收支观测资料及同期NOAA-7辐射收支资料,用统计方法讨论了大气顶净辐射与地表净辐射之间的相关性,建立了两者之间的回归方程,并在此基础上分析了青藏高原地区月平均地表净辐射的时空分布特征。
urface net radiation flux is the difference between net radiation flux at the top of the atmosphere (TOA) and net radiation flux within the atmosphere. The relationship between surface net flux and TOA radiation budget can be expressed by different formula with different parameterization assumption of net flux within the atmosphere. In this paper, utilizing the NOAA-7 radiation budget data and the simultaneous surface radiation data over Qinghai-Xizang Plateau during the period from August 1982 to July 1983. the relations of them are discussed and the regression prediction equations are derived for deriving the monthly mean surface net flux from satellite observations. On the basis of above analysis, the spatial distributions of the monthly mean surface net flux are analysed.
