Christian, The WMO synoptic code uses different tables for manned and unmanned reports (automated 4680 and manned 4677). The WWMO GEMPAK parameter is the manned table 4677 value (or equivalent converted from the 4680 value). The decoder converts the automated weather code to the manned weather code in $GEMPAK/source/gemlib/pr/prwmao.f. In that routine, you willfind that "43" from table 4680 is converted to the equivalent "63" value for table 4677 for storage in the GEMPAK WWMO parameter.

Hi everyone,
I noticed maybe a problem in dclsfc. I am using GEMPAK .
By example, the following synop message:
71725 17964 00504 10096 20039 39871 40289 53008 60001 743// 333^M^M
10157 20034 70005=^M^M
is decoded to:

WWMO is thus 63, but it should be 43!! 743// in the synop code. There
was indeed no rain (wmo code 63), but only fog (wmo code 43). Is there
a problem?
