A comprehensive scientific evaluation of the model quality is currently ongoing and will be made available in the coming months.

This page will be continuously updated as issues get resolved.

An issue was found with the snow layer of the surface model which led to the erroneous removal of the snow layer. In snow-covered areas , this led to significantly different albedo and consequently a lot of unexpected warming.

Therefore, this data was deleted and was replaced over the course of September 2025.

It should be noted that low latitudes and a large proportion of the European region is not significantly affected, and therefore for many users the new simulation will not have a significant impact.

  • Geopotential on pressure levels ( 129 ( Geopotential [m2 s-2] on levtype pl) shows non-realistic values over orography
  • Parameter 168 (2 metre dewpoint temperature [K] on levtype sfc) has zero values for the entire simulation.
