KMA (rksl)

Wind components fields on pressure levels  (might impact ANY KMA outputs). Fixed by the 10th of October 2017 in all KMA data (real-time and reforecast) by re-archiving.
Info

1. Brief  description:

The data values for U/V component parameters on the pressure levels are often clearly wrong (e.g. the maximum (global) value of U component 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 in both real-time and reforecast outputs.

500hPa geopotential height issue (since 29 Mar 2017) Fixed by the 10th of October 2017 in all KMA data (real-time and reforecast) by re-archiving.

1. Brief  description:

The data fields of geopotential on pressure levels 500 hPa geopotential and higher are wrong as per attached examples since the 29 March, 2017 are wrong as per attached examples.

2. Recommendation:

Wait for fix in both real-time and reforecast outputs.

JMA (rjtd)

The valid times of the maximum/minimum temperature are wrong  in the re-forecast data (impacts ALL hindcast data for the model version: 2014-03-04).
