GITS-CEN, Shortwave radiation: values multiplied by ~2 in GC-Net data

The linear regression between the ISWR at CEN and GITS indicates that there is a multiplicative correction of 0.385 applied to the GITS data would minimize least squared error. It is used for adjustment of both ISWR and OSWR for all years after 2012

Least squared regression for hours with more than 100 W/m2 indicate a slope of 0.385 between the ISWR at GITS and CEN. We apply this multiplicative correction coefficient to all year at GITS after 2012.

I now identified that this issue comes from calibration factors improperly set in the way CR1000 logger files are being read. This is now solved through the calibration factors and not through this 0.385 multiplicative adjustment.
