I downloaded CERRA grib data of 173 Go. Here is the informations of the grib2 file :
By this code i try to get ws variables for all timestamp in particular lat,lon:
lat = 47
lon = 4.9
abslat = np.abs(ds.latitude-lat)
abslon = np.abs(ds.longitude-lon)
c = np.maximum(abslon, abslat)
([xloc], [yloc]) = np.where(c == np.min(c))
dfb = ds.sel(x=yloc, y=xloc,heightAboveGround=100)
The informations of the new xarray.Dataset is :
Finally, i want to get all values of variable ws :
dfb.to_dataframe()
It should return a dataframe of 18984 value for each time. Unfornately, I have this error :
For me, it's not the expected shape of the dataframe. I tried to limit the number of ws value by :
dfb.ws[:100].to_dataframe()
And it returns as expected :
