Describe the Enhancement

Note that this work was performed using the GRIB2 table input from:

• wgrib2 version 3.1.4 gribtables (a separate development branch prior to the transition to GitHub) from:
  hera:/home/Wesley.Ebisuzaki/grib2/wgrib2/gribtables
• wgrib2 version 3.4.0 gribtables
  • See Fix suspicious GRIB2 table entries NOAA-EMC/wgrib2#285 for some of the issues/discrepancies I found.

This issue was discussed during the METplus NOAA User Telecon on Jan 8, 2024 (see meeting notes - limited access). Gwen indicated that wgrib2 version 3.1.4 is under development and will include updates to some of the GRIB2 tables. Note that wgrib2 has migrated to GitHub at NOAA-EMC/wgrib2.

NCEP GRIB2 tables have been updated with new WMO-approved variables (27 freezing/melting potential, 28 melt onset date, and 29 freeze onset date in Table 4.2-10-2 and Level 172 in Table 4.5).

A new release v3.1.4 will be installed on Acorn soon for testing. If successful, it will be delivered to WCOSS2.
Use the v3.4.0 release from 8/15/24 instead.

This issue is to:

• Download the v3.1.4 release when it becomes available.
• Update the contents of the GRIB2 table files in data/table_files/grib2_*.txt as needed.

Recommend requesting that Gwen (Li-Chuan Chen) serve as the tester for these table updates.
