The Nimbus 7 ERB data set - A critical analysis

摘要: An analysis of the first year NIMBUS 7 earth radiation budget data set reveals that there are systematic differences between wide and narrow field view measurements. The larger appear in albedo due primarily to a bias introduced by processing method. There smaller differences, associated with outgoing longwave radiation, which probably errors calibration. originates factors used for converting shortwave intensity measured at satellite altitude into mean daily top atmosphere. factor proves most troublesome is one converts total instantaneous flux. That determined angular distribution models, depend upon type scene within target area. alternative method data, model independent, shown have practically no yields better overall agreement
