Annual cycles of the daily integrated SSR for the maximum possible clear-sky solar irradiance (reference value) and the all-sky average irradiance for (a) EUV, (b) TUV, and (c) GS total spectrum from March 2004 to February 2013. The solid and dashed lines show the envelope curves of the data maxima and the curves of the all-sky average values, respectively.
