Issues with data

Please be aware that the issues with data on this page are rather the more recent ones. Because of the length of TIGGE project (since 2006) and its only research status (not production) we are aware of other old issues in the past which have not always be properly reported and thus captured. Please let us know in case you encounter any data issue in TIGGE dataset.

1. Brief  description:

The values of Skin temperature parameter contains unrealistic values over ocean.  The values are correct over land, but not over the ocean because a surface scheme variable is wrongly used there.  This configuration was setup at the beginning of TIGGE (2006), when the Canadian ensemble system was not coupled with ocean. Now that Canadian ensemble system is coupled, thus an update is needed to be able to use an aggregated skin temperature valid over land and ocean.

2. Recommendation:

Users should be aware of that issue which has been fixed since 12Z, 25-05-2021

1. Brief  description:

The values of the encoded ensemble size (GRIB2 key numberOfForecastsInEnsemble) were wrong.

2. Recommendation:

Users should be aware of this purely technical issue.

1. Brief  description:

After the KMA model update on 1.8.2022 the values of  Surface net solar radiation were wrong . Also there were some occasional unwanted zero values for some other parameters (like 2t, 2d, tcc, 10m u/v etc).

2. Recommendation:

Users should re-download the fixed KMA data from the described period if they got them during the period 1.10.2022-20.1.2023 in the past.
