Lat orientation differ
Added by Josh Butterworth over 6 years ago
So I'm brand new to using UNIX/CDOs and I'm currently trying to generate some statistics for a dataset that I've been given as I complete a workshop tutorial. When I try and calculate a correlation coefficient between a model and observations I'm receiving the following message:
"cdo timcor (Warning): Latitude orientation differ! First grid: N->S; second grid: S->N cdo timcor: Processed 546624 values from 2 variables over 52 timesteps [0.03s 13MB]"
All it seems that I need to do is change the latitude orientations, which is probably quite simple? However I really am completely new to this and I've no idea how to do this, any suggestions?
Thanks in advance,
J

Hi Josh,
have a look at the CDO FAQ page:

The invertlat operator does what you want.
