WMO Heading and Super Heading Reference

World Meteorological Organization (WMO) Headings have the format of T1T2A1A2ii CCCC.

WMO super headings are used to aggregate products for the
same parameter (NDGD element) and sector.  These aggregate
products contain individual products for all forecast periods.
For these aggregate products the WMO Super Headings are
consistent with those for individual NDGD products except in
the super headings, the  A2 is always Z.

The CCCC for all EKDMOS product WMO headings is KMDL (indicating
they are produced by MDL)

The T1 = H, L, M, V, Y and Z for all GRIB2 WMO Headings.

H = UNASSIGNED
L = Conus
M = Alaska
V = UNASSIGNED
Y = Puerto Rico
Z = Hawaii
