Hi Steve, Hi everyone,I made many modifications in GEMPAK, I don't know if a few could be interesting to include in the next official version (it would also save me some work each time GEMPAK is updated ;-) ). I will only list the modified files for now and send you the ones you think could be included.
1) SFUK packing table (European lightning data : sferics) gempak/tables/pack/sfuk.pack 2) SFUK decoder (European lightning data : sferics)I built the decoder from scratch, so the source code may not comply to GEMPAK standards.
3) Tenth precision in precip amounts for dclsfc gempak/tables/pack/sfsyn.pack gempak/tables/pack/lsfc.pack 4) 30 min bins for dcmetr gempak/source/bridge/dc/dcgtim.f gempak/source/bridge/mt/mtdcod.f5) 30 min bins and also SPECI included in decoded data in a separate instance of dcmetr called dcmetr_speci
gempak/source/bridge/dc/dcgtim.f gempak/source/bridge/mt/mtdcod.f 6) 1h bins SYNOP data in a separate instance of dclsfc called dclsfc_1h gempak/source/bridge/ls/lsgemp.f7) GEMCLRBAR environment variable added to control the display of the colorbar
gempak/source/gemlib/im/imdrop.f8) More complete list of european/canadian stations, as well as ordering changes
gempak/tables/stns/sfmetar_sa.tbl gempak/tables/stns/lsfstns.tbl 9) More complete upper-air soundings stations list cat snstns.tbl snstns_land.tbl snstns_ship.tbl > snall.tbl 10) Europe-decoded MAX/MIN temperatures gempak/source/bridge/ls/lstemp.f gempak/source/bridge/ls/lswgem.fAlso, any hope to see values like 10.2 displayed by sfmap or related programs?
