probelm when transfering wind vector from rotated grid to geographical coordinate system using rotuvb
Added by Delei Li over 10 years ago
Dear all,
I got a modeled (CCLM model) wind vector data with rotated grid. and used rotuvb command to transfer to geographical coordinate system as:
cdo rotuvb,U_10M,V_10M UV_ts.nc UV_geo.nc
but error is: cdo rotuvb (Abort): Only rotated lon/lat grids supported. I am confused because I have ever used this command to the same file before and it worked well. Why it did not work this time?
Thanks very much in advance for any information.
Best regards,
Delei

This file contains data on an rotated lon/lat grid and the corresponding geographical coordinates on a curvilinear grid. CDO can handle only one coordinate system for a variable. Because of the coordinates attribute the curvilinear grid is used. You can set the environment variable IGNORE_ATT_COORDINATES=1 to ignore the coordinates attribute. In this case the coordinates of the rotated grid is used.
