[develop] Add verification of snowfall accumulation (#853)
This PR adds relevant METplus configuration files and modifies various scripts to allow for verification via the NOHRSC gridded accumulated snowfall product. The forecast variable created by post is 'TSNOWP' for 6-and 24-hour snowfall accumulation with a fixed density, which will be verified on a 6- and 12-hour cadence, respectively. When the GSL variable-density snowfall product is included in post in the future, the variable in the METplus configuration files may be changed to 'ASNOW'. Currently this addition does not turn on accumulated snowfall verification by default. This is because NOHRSC observations were not located on NOAA HPSS previous to March 2020, as well as the idea that many non-winter cases likely will not desire to run the additional verification tasks. This PR achieves removal of snowfall verification tasks by omitting it by default from the VX_FIELDS variable. Therefore, to turn on snowfall verification, users may simply include VX_FIELDS in their configuration with "ASNOW" added. This PR also turns off all “ncpairs” file creation in METplus configuration files. These files represent the majority of the filespace footprint for METplus outputs, and are not necessary to produce verification statistical output.
