[IDV #RZP-160177]: unable to read netcdf file.
- Subject: [IDV #RZP-160177]: unable to read netcdf file.
- Date: Wed, 16 Dec 2015 08:51:29 -0700
Mark,
The only problem with test5.nc is the "days since Jan 1" is not a CF compliant
time unit.
Try something like "days since 2015-1-1 00:00:00 UTC".
When I try that change, your file can be read by the IDV.
Best,
Unidata IDV Support
