[Go-essp-tech] User Response: CMIP5 archive Question/Problem [ESG-PCMDI] hfds for CNRM-CM5 & NorESM1-M ISSUE=701 PROJ=17

Wed Feb 8 13:40:43 MST 2012

Hello,

we had similar issues (dimensions mixing).

Upgrading to ferretv6.722 solved the issue. I can't remember the ferret 
version number fixing that.

regards.

If ferret is not finding this then it looks like a problem with ferret or your configuration of ferret -- if it is a software issue you are more likely to get support on the go-essp-tech list (which I've copied this to) or from the FERRET support team,
