Error using remapbil: Unsupported generic coordinates (Variable: E)!

Added by Diego Araujo over 1 year ago

Hello!

I need some help. :)

I have a file with global evaporation data from GLEAM, with daily data. I need to clip this global file to an area of interest (northern part of Morocco). I created a .nc file in QGIS using the original GLEAM file, but clipping it just to the area of interest. Now, I need to clip the original file (since the clipped file in QGIS doesn't have all the daily data layers, i.e., 365 days of data).

I was trying to follow this procedure to match the projections and then clip:

  1. regrid
    cdo remapbil,e_gleam_2017.nc mask_morocco.nc remap_mask_morocco.nc
  1. mask
    cdo ifthen remap_mask_morocco.nc e_gleam_2017.nc masked_e_gleam_2017.nc

The error is: Unsupported generic coordinates (Variable: E)!

Does anyone know how I can resolve? Or is this the wrong way to clip?

Attached you can find the reference file (mask_morocco.nc) and the file to be cut (in the attachment is the annual total, as files with daily data exceed the maximum size, but the structure is the same)

Download all files
masked_morocco.nc (10.2 KB) masked_morocco.nc
e_gleam_2017.nc (4 MB) e_gleam_2017.nc

Hi Diego,

the file dimensions lon and lat do not have a units attribute. You can add it with NCO's ncatted before you do the remapping and masking.

ncatted -O -a units,lon,c,c,"degrees_east" -a units,lat,c,c,"degrees_north" e_gleam_2017.nc

cdo -remapbil,e_gleam_2017.nc masked_morocco.nc remap_mask_morocco.nc
cdo -ifthen remap_mask_morocco.nc e_gleam_2017.nc masked_e_gleam_2017.nc
