In November 2018, an error was reported affecting the following data in the climate data store (CDS):
CDS Dataset | ERA5 hourly data on pressure levels from 2000 to present |
---|---|
Parameters affected | U-component of wind, V-component of wind |
Level | All pressure levels |
Time periods affected | 01 Jan. 2000 - 31 Dec. 2008 01 Jun. 2018 - present |
This problem was caused by the computation of U/V from Vorticity (Vo) and Divergence (D) already interpolated on a regular grid in CDS. U/V should be have been computed from Vo and D in spherical harmonics representation (the native gridmodel representation) and then computed U and V can be interpolated on interpolated to a regular grid for storage in before saving to the Climate Data Store.

can I do if I downloaded the wrong data?
Because this error has not yet been fixed, this means that any data corresponding to the description above is wrong, and will continue to be wrong until a fix is in place. You should not use this data and wait until the problem is fixed.
