Hello, i try to convert wind file ( u, v) to divergence and verocity file with cdo uv2dv data.nc data_out.nc. It appears this message " cdo uv2dv (Abort): U-wind is not on Gaussian grid! "

Hi Francis,

can you upload the data file? It is not possible to help without more information about the data file.

Hi Karin, you are right.
finaly i succeed to convert to gaussian grid an calculate the velocity potential ( infile : velocity_pot.nc) after that when i try to open in GrADS, here is the message provided :
sdfopen velocity_pot.nc
Scanning self-describing file: velocity_pot.nc
Error: nc_open failed to open file velocity_pot.nc
No such file or directory
gadsdf: Couldn't ingest SDF metadata.

This is my wew chanllenge
thanks

velocity_pot (3.66 KB) velocity_pot velocity potential file

And again, without any data file it is not possible to help ;) Can you upload the velocity_pot.nc file?

Btw, it is better to use the copy operator to convert to F64 instead of mergetime (without the -O option it merges with potential existing file and may cause other problems).
