Quality controlled observations of hourly incoming shortwave radiation data at the surface for solar resource mapping in Norway (2016-2020).

Observed hourly incoming shortwave radiation data at the surface of Norway for the years 2016-2020 along with quality control flags, visualization plots and a descriptive report. The data has been collected, visually inspected and quality controlled within the SunPoint project (SUn in Norway - POtential and INTegration of the solar energy resource, Norwegian Research Council project 320750). The main data source is frost.met.no but some gaps were filled with data directly obtained by the station holders.

There are three NetDCF files for 47 stations selected after quality control:

rsds_1hr_selection_v5_2016-2020.nc: Raw data

rsds_flagged_1hr_selection_v5_2016-2020.nc: Raw data with flags

rsds_cleaned_1hr_selection_v5_2016-2020.nc: Filtered data (i.e. all flagged data has been removed)

and one NetCDF file for all available stations (106 stations)

rsds_1hr_frost_and_more_2016-2020.nc

Version 3.5 of the McClear clear-sky model is used for flagging which reduces the bias to ground measurements compared to earlier versions. 

The visualization and automated quality control routines are available in the Scripts.zip file (python).
