Initial Request
----------------------------------------------------------------
Hi,
I am trying to use the "regrid_data_plane" function to regrid a data
file, but I got the error message:
my command: ./bin/regrid_data_plane ./out/RAW_NEX_GRID20110520_12.cdf
G213 ./out/regrid.nc -field 'name="Hourly_Rain_Grid"; level="(*,*)";
file_type=NETCDF_NCCF;'
ERROR : NcCfFile::read_netcdf_grid() -> Couldn't figure out
projection from information in netCDF file.
But it's on regular lat/lon grids, so there's no projection needed. Do
you know why?
Thanks,
Jia

Hi, Minna,
Thanks for your response.
I have a general question, are there any templates to demonstrate how
to evaluate the WRF precipitation forecasts, either use traditional
scores or object-based scores?
If there're no such templates available, I recommend the MET team
considering this possibility, because I think including some general
templates could much improve the understanding of MET functionalities.
Thanks,
Jia

Hello Jia. I apologize for next writing you much sooner. In fact I
did
write the following response back on August 22, but unfortunately, I
sent
it the wrong place! It didn't make it into our RT ticketing system.
Here's that email...
Thanks,
John
Hello Jia. You make a very good point about templates for recommended
configurations of the MET tools. In fact, that is what motivated the
development of METplus in the first place! If you're not aware of
this
(and you may not because we don't have good info posted to the DTC
website
yet), METplus is a set of python wrappers used to automate calls to
the MET
tools. One main goal is providing many use cases with examples
showing how
the MET tools are called to perform various task, such as QPF
verification.
For now, I see that you have a NetCDF file that MET doesn't know how
to
read. Can you please post it to our anonymous FTP site? I'll grab it
and
go take a look.
Please take a look at the "How to send us data" section of this page:
https://dtcenter.org/community-code/model-evaluation-tools-met/met-
help-desk
Thanks,
John
