OSWR miscalibration at NASA-U

[BaptisteVandecrux]

From #10 :

At NASA-U, the upward shortwave radiation seems to be divided by a factor of ~2.5. Is there an issue with the conversion of the data logger’s data into standard units? We now tune the correction coefficient to 2.76205 so that station albedo matches MODIS albedo for June July and August (minimize bias).

From Koni's file, I could identify that two calibration coefficients are possible for the OSWR. 77 V/(W/m2) or 200. Currently 77 is used for 2012-2022 but potentially 200 should have been used for that 2003-2018.

From Koni's Matlab processing script, 200 was used for 2015-2016 and 77 after. I cannot see what was used before 2015.
