Detailed Description

Generate solar radiation out of daily sums.

Daily sums of solar radiation (once, per day, any time during the day). Data provided at midnight is considered to belong to the day that just finished) are compared to the potential radiation, leading to an atmospheric loss factor. This loss factor is then applied to the potential solar radiation calculated at the requested time. When using this algorithm for RSWR, an albedo is required. A default value of 0.5 is used. If the snow height is available and greater than a 10cm threshold, a snow albedo is used. Below this threshold, a soil albedo is used.
