The metar.pack file in 5.6 uses TMPC & DWPC. So, the decoder couldn't find a matching parameter to write TMPC out to. PMSL was fouund, so you saw those values. In 5.6, a surface file can contain 29,000 different unique station IDs (the sfmetar_sa.tbl file only contains ~4000 stations), so number of stations is not a problem. Steve Chiswell
