Hello,

I can't tell if you're asking:

* How to tell what information is in your netcdf file,

* How to get the data you need out of your netcdf file,

* How to interpret the data you are getting from the netcdf file.

Perhaps you could be a bit clearer?

As a suggestion, try "ncdump -h <filename.nc>" and look to see what
information is in your file. Is it what you expected & need?

Regards,
