What's wrong?
An error has been detected In November 2018, an error was reported affecting the following data in the climate data store (CDS):
| CDS Dataset |
|---|
...
...
| 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 grid-point Vo/D, but it should be done from Vo/Vorticity (Vo) and Divergence (D) already interpolated on a regular grid in CDS. U/V should be computed from Vo and D in spherical harmonics representation (native grid) and then computed U and V can be interpolated on a regular grid for storage in the Climate Data Store.
What do I do if I downloaded the wrong data?
Because this error has not yet been fixed yet, this means that any data corresponding to the description above which have been retrieved so far 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.
When will the issue be fixed?
It is estimated the problem will be fixed before the end of November. Exact details of when the problem is fixed will be provided in the on this page.
