  1. Add the newly added WMO definition to paramId 47 (Direct solar radiation)?

  2. The WMO calls 0,4,13 "Direct short wave radiation flux"

  3. We could probably use the already defined parameter called "Total sky direct solar radiation at surface" (228021). In that case the WMO GRIB2 definition (at surface) would have to be added.
