Environment wind from ERA-5 #120

Open gab1092 opened 2 years ago

gab1092 commented 2 years ago

Hello! I'm testing some configurations with different data sources, I was able to load data for the environment wind object from GFS, but I'm not able to load the data from ERA-5. The error message is ValueError: No compatible variable names found! But when I used the same data for the wind movers, I could load the data without problem; any idea for loading the data as an environment variable? Here is the code which I used.

wind_obj = GridWind.from_netCDF('/home/GNOME/ERA5/2015_2016.nc') ValueError: No compatible variable names found!

for the movers, I could run without problems

file_wind='/home/GNOME/ERA5/2015_2016.nc' w_mover=GridWindMover(file_wind) model.movers += w_mover

Thank you!

The compatible variable names error happens when an environment object can not find compatible variables to use. That is to say, it simply could not find them. Passing a varnames = ['u_name', 'v_name'] kwarg would be enough for it to work.

What are your imports? I'm guessing you are using the legacy GridWindMover object (a self-contained mover), when only the new PyWindMover would use the GridWind environment object. If the GridWindMover could do the job though, that's good enough I suppose.

Thank you! With your suggestion I could import the wind as environment object! However I need import as wind movers with GridWindMover because I can't use the wind_obj as a grid mover, but It's working.
