Notes:

* Parameter deprecated - See Regulation 92.6.2 and use another parameter instead.
** Total precipitation/snowfall rate stands for the sum of convective and large-scale precipitation/snowfall rate.
*** Statistical process 1 (Accumulation) does not change units. It is recommended to use another parameter with "rate" in its name and accumulation in PDT.

(1) The numeric value is a reference to a weather string and key table stored in the Local Use Section (Section 2) of the same GRIB2 message. See MDL Template 2.1 page and this page for more details.
