1. Brief description: The data fields of geopotential on pressure levels 500 hPa and higher are wrong as per attached examples since the 29 March, 2017. 2. Recommendation: Wait for fix in both real-time and reforecast outputs. |
Soil initial data issue affecting mainly surface fields in the real-time forecasts (9-17.6.2019). Fixed by the 25th of June 2019 by re-archiving.

1. Brief description: Wrong soil initial data has been used in the real-time forecasts. Please refer to the below graphs and maps illustrating the issue (see soil initial fields and comparison of forecast anomalies).
2. Recommendation: If KMA real-time data from the given runs was downloaded in the period 9-25.6.2019, it should be deleted and the correct version of the data downloaded again. |
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).

1. Brief description: All S2S parameters were affected in that period. The corrected data was re-archived on June 17 2016. The problem on the provider's side was caused by a bug in the last versions of EMOS and MARS (issued in March) that was avoided by using the previous version of MARS. 2. Recommendation: If lfpw M-F data from the given period was downloaded in the period 19.5.2016-17.6.2016. it should be deleted and the correct version of the data downloaded again. |

1. Brief description: Four hindcast runs on 13., 17., 20. and 24.6. 2019 had to be re-computed and re-archived after ECMWF model upgrade to the new cycle 46r1 on June 11 to have both types of forecasts for S2S archive, real-time and hindcast, produced by the new model version. This problem could happen because the hindcasts are computed well in advance before the actual real-time date. 2. Recommendation: If you downloaded the affected ECMWF hindcast data from the given runs was downloaded in the period 30.5.-25.6. download it once more to have consistent hindcast data produced by the same model version as the real-time forecasts from IFS model2019, it should be deleted and the correct version of the data downloaded again. |
