CDO

Hello! I am attempting to regrid a RCM precipitation data set from a rotated pole projection to a regular lat-lon projection using remapcon. However, I am receiving an error I am not sure how to resolve. Any advice/insight into 1) what is causing this issue and 2) how to resolve it would be much appreciated. For reference, I am using cdo version 1.9.4. Thanks!

The error is the following: cdo remapcon (Abort): Unsupported generic coordinates (Variable: block1)!

Command: cdo remapcon,RACMO2_output_grid_description.txt -setgrid,RACMO2_input_grid_description.txt precip.KNMI-2001.DMIS055.ERAIN.DD.nc regrid_precip.nc

The input grid descriptions are as follows:
gridtype = projection
xsize = 486
ysize = 200
xunits = 'degrees'
yunits = 'degrees'
xfirst = -12.25
xinc = 0.05
yfirst = -4.75
yinc = 0.05
grid_mapping_name = rotated_latitude_longitude
grid_north_pole_longitude = 13
grid_north_pole_latitiude = -161

The output grid descriptions are as follows:
gridtype = lonlat
xsize = 86
ysize = 15
xfirst = -29
xinc = 1
yfirst = -77
yinc = 1

ncdump command: "ncdump -h precip.KNMI-2001.DMIS055.ERAIN.DD.nc" yield the following:
