Nimbus-7 Earth Radiation Budget (ERB) Long-Term Means

Climatologies for each month and field have been produced. The analysis system changed for the Nimbus-7 ERB data in July 1980, so data prior to this time have not been used in the averages. Specifically, data from the last seven years (November 1980 through October 1987) of measurements have been used in the construction of monthly averages. No other attempts have been made to correct for possible biases in the data.
