Because of the dependence of aerosol direct forcing on solar zenith angle, the daytime variation of aerosol properties doesn't directly translate into that of direct radiative forcing. Our goal is to assess what uncertainty is introduced to the direct forcing calculation by neglecting aerosol daytime...
The Vaisala cloud algorithm then divides the satellite measurements into bins by solar azimuth and zenith angle, and treats each bin independently for the calculation of a cloud index. The fit between cloud index, clear-sky GHI, and observations is done on a per satellite basis. ...

Irradiance measurements were conducted under clear blue sky, at 12:20 to 14:09 (local time), with solar zenith angles of 46° to 55°, and under light winds of 1.8 m/s. Note that various elements included in the spectroradiometer setup may introduce spectrally-specific variation in the ...
