[Met_help] [rt.rap.ucar.edu #91422] History for Example/help using a timestring for netcdf files

[Julie Prestopnik via RT]

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

Hi

I would like to use the new feature discussed in the release of MET 8.0:
"Enhanced the NetCDF library to request data using a timestring instead of requiring an explicit index for the time dimension."

I assume this can be used for "field" entries. However, I did not see any examples of this in the turorial. This new approach would be much better than finding the correct time index and using the syntax:
level = "(0,5,*,*)";

Can you please give me an example of how to do this?

Thanks,
Scott

Hi Scott.  It looks like the file was too large to send in my response
below. I'm not sure if my email went through either, but you can see
it
below.  My apologies.

I'm attempting to attach it as a Google Drive link below.  I hope this
will
work.

I could also put it on our ftp server if this does not work.
