GFDL-CM4 SfcWind height Issues #2384

Closed Karen-A-Garcia closed 4 months ago

Karen-A-Garcia commented 5 months ago

Describe the dataset issue I've recently found an issue in the GFDL-CM4 surface wind (sfcwind) height coordinate. When I was preprocessing the data for analysis, I found that I kept getting an error saying:

ValueError: Can not concatenate cubes: failed to concatenate into a single cube.
  Scalar coordinates values or metadata differ: height != height

I was checking the cmor fixes in the ESMValCore directories and it seems there was a height fix where 2m of height was added. From my understanding sfcWind uses 10m height which could maybe causing this issue?

The full issue is a little hard to read because I was using dask but this is the last call that I can see before the big error message at the bottom of main_log_debug.txt
