CDO

Hi,
I want to regrid CERRA data to rotated latlon so that it is compatible with JRodos software and so that the grid is coarser.

My questions:

1. Do u,v vectors need any special treatment like rotating from grid-relative form to another or is "cdo -f grb2 remapbil,mylcc_regrid14rgll.txt uv_lambert.grib2 uv_latlon.grib2" command enough to interpolate the vectors correctly?

2. When interpolating to another hybrid model level structure, does cdo automatically detect that it is dealing with velocities or do u,v need to have specific variable names or parameter ids?

The content of mylcc_regrid14rgll.txt:
gridtype = projection
gridsize = 31073
xsize = 193
ysize = 161
xname = rlon
xlongname = "longitude in rotated pole grid"
xunits = "degrees"
yname = rlat
ylongname = "latitude in rotated pole grid"
yunits = "degrees"
xfirst = -10.000
xinc = 0.125
yfirst = -16.500
yinc = 0.125
scanningMode = 64
grid_mapping = rotated_pole
grid_mapping_name = rotated_latitude_longitude
grid_north_pole_latitude = 32.5
grid_north_pole_longitude = -170.0
north_pole_grid_longitude = 0.0

Thank you,
Michał
