Hi Upendra,
My plane was delayed ...
Please, find attached the draft CF-netCDF data model specification that
Ben and I are developing for the OGC.
In this version of the specification, the CF conventions are still
version 1.1. However, I have been working to update them to 1.5 --as was
decided at the last OGC netCDF SWG meeting in Bonn.
I hope that helps.
