An analysis of the periodicities found in the Nimbus-7 satellite measurements of solar irradiance (Solar Constant) indicates
variations on three scales. Two of these variations are shown to be related to variations in solar activity as given by various
indicators of solar photosphere disturbances. The high frequency periodicity is due to the solar rotation period. The second
periodicity is based on the integral effect of the high frequency oscillation over an 11 year solar cycle. The third variation
(secular trend) is discussed in regard to the high precision cavity data and the recent record of high altitude solar constant
measurements. 相似文献
