地表辐射收支资料是1983年7月和10月以及1984年1月和4月的季节中期。这些数据首次使我们能够考察整个地表辐射收支在两极之间的地理和季节变化。最新通量估算技术已与国际卫星云气候学项目（ISCCP）和地球辐射收支实验（ERBE）的数据一起使用。确定了短波和长波通量以及净地表总通量的向下分量和净分量的区域、纬向和半球分布。每个区域的季节通量变化，表示为通量范围，也说明了这些成分。根据敏感性分析和与地面数据的比较，估计的通量在全球平均水平上似乎精确到约16wm - 2。对磁链误差的分析表明，大部分误差是由输入数据的误差引起的。
Surface radiation budget data are presented for the midseasonal months of July and October of 1983 and January and April of 1984. These data allow examination for the first time of geographical and seasonal variations of the entire surface radiation budget from pole to pole. The latest flux estimation techniques have been used along with data from the International Satellite Cloud Climatology Project (ISCCP) and the Earth Radiation Budget Experiment (ERBE). Regional, zonal, and hemispheric distributions of the downward and net components of both shortwave and longwave fluxes and of the net total surface fluxes are determined. Seasonal flux variation per region, expressed as flux range, is illustrated for these components also. The estimated fluxes appear to be accurate to about 16 W m−2 on a global average, based on sensitivity analyses and comparisons with ground data. An analysis of flux errors showed that most of the error was attributable to errors in input data.
