Event(s):

CDP (Col de Porte) * Latitude: 45.300000 * Longitude: 5.770000 * Date/Time Start: 1993-08-01T00:00:00 * Date/Time End: 2011-07-31T00:00:00 * Elevation: 1325.0 m * Location: Chartreuse range, France * Method/Device: Weather station/meteorological observation (WST)

Comment:

Two masks (up and down) are given (in ° above horizon), as a function of solar azimuth (0 is true North). Between mask up and mask down, only a fraction (percentage) of the direct solar radiation reaches the ground. Below the mask down elevation angle, 100% of the direct solar radiation is cut. See further details for a plot of solar masks.
