CDO

Hi,

I am recently handling the ocean variable produced by the IPSL model (submitted to the CMIP5). I found it is not the irregular output.

How to convert it to the regular one? I have a try to use the operator: cdo remapbil,r360x180 -selname,thetao in.nc .out.nc

as a relsult, It does not work. the error information is :

cdo remapbil: Started child process "selname,thetao thetao_Omon_IPSL-CM5A-LR_rcp45_r1i1p1_200601-205512.nc (pipe1.1)".
Warning (scanVarAttributes) : NetCDF: Variable not found - areacello
Warning (define_all_grids) : Unsupported array structure, skipped variable thetao!

cdo(2) selname: Open failed on >thetao_Omon_IPSL-CM5A-LR_rcp45_r1i1p1_200601-205512.nc<
Unsupported file structure

To my surprise, my friends employ the same method and same input file succeed.

My CDO version is 1.5.3, Would you please give me some suggestion to solve this problem ?

Thanks in advance.

Have a nice day
