NetCDF as input

Post by skew_t_pie » Mon May 18, 2020 8:38 pm

I am reading data through MATLAB which is unpacked using their NC-Toolbox. As I understand it, the WPS takes GRIB data, re-purposes it to an intermediate format, then to NetCDF? If this is the case, can I by-pass the "ungrib.exe" process if the input data is already in NetCDF? It doesn't matter if the data I'm reading through MATLAB is GRIB or NetCDF; the toolbox can unpack either. However, I do not know of any software in MATLAB that writes to GRIB but writing data to NetCDF is pretty straightforward.

If the data is in netCDF format, you definitely can skip running ungrib. Instead, you can read the netCDF data directly, write it to intermediate files, and then run metered.exe.

The format of intermediate file can be found in https://www2.mmm.ucar.edu/wrf/users/doc ... gical_Data

OK, thank you very much
