Initial Request
----------------------------------------------------------------
Good afternoon met_help,
I am trying to use MET to verify WRF runs against a locally generated NEXRAD precipitation estimate. I use matlab so the local precipitation data is not in GRIB. I did however figure out how to create a netcdf from the data that matched the output from pcp_combine. The problem is that my data is lat/lon based so I set up the netcdf with the appropriate lat/lon attributes to match my data. When I ran grid_stat and mode on the data I got this error: read_netcdf_grid_v3() -> Projection type Lat/Lon not currently supported.
I used lat/lon because the tutorial and handbook say that lat/lon is supported.
Should I try to reference my data to another projection? Is there a better way to get my data formatted as an input for grid_stat and mode?
I can provide files etc. if your require them.
Thank you for your time,
John D McMillen

John,
I see that you're having trouble getting gridded data formatted in a
way for the MET tools to read them.
Yes, the lat/lon projection is supported. I suspect there's a minor
formatting issue causing the problem. Please check the NetCDF file
you created to see if the "Projection" attribute is set exactly
to "LatLon". If, for example, it was set to "lat/lon", you'd get the
error you're seeing.
If that fixes the problem, great. If not, please send me a sample
NetCDF file and let me know what version of MET you're running. You
can post data to our anonymous ftp site following these
instructions:

Hope that helps.
Thanks,
John

Wow,
Great response time!
You are correct, I added a slash and that caused the error.
Thanks,
John

Great, glad that did the trick. Thanks for letting me know.
Just let us know if any more issues or questions come up in your use
of MET.
Thanks,
John
