downwelling shortwave flux - 5 min average

Incoming shortwave radition, measured at a height of 2 m above ground, averaged over 5 min interval with time label at end of bin. The instrument response integrates over the whole upward-looking hemisphere and the wavelength range from 305 to 1200 nm. This timeseries is a continuation of measurements taken at the former town station since 2010. The town station was converted into a GEM climate station in 2016.

quality
Variable description
Flag assigned during quality control. The flag value 'unknown' is equivalent to the flag 'good' or 'fair' and is due to a change in procedures. Work is underway to update these flags.
