KMA (rksl)

Wind components fields on pressure levels  (might impact ANY KMA outputs).
Info

1. Brief  description:

The data values for U component parameter on the pressure levels are often clearly wrong (e.g. the maximum (global) value is in one case -14.4178 m/s  which is not in the allowed interval [1,250] verified by the ECMWF's checking tool). That error was acknowledged by KMA and it was tried to fix it in some forecast outputs.

2. Recommendation:

Users should consider it when using KMA wind component fields on the pressure levels.
