Hi John, Tell me about the complexity of BUFR... The last two files were meteorological SYNOP files coded according to the WMO standard tables for FM94 BUFR Edition 4: http://www.wmo.int/pages/prog/www/WMOCodes/TDCFtables.html It uses the common sequence 3-07-080 (= Sequence for representation of synoptic reports from a fixed land station suitable for SYNOP data) from table D.
ill have a look at that when i can
I also use a ECMWF bufr decoder package (http://www.ecmwf.int/products/data/software/bufr.html). Attached is 'decode_bufr.txt' which is a dump of test1.bufr using the decode_bufr program in this package. The output compares well with what I see in toolsUI 4.2.
seems ok, ive appended our numeric dump of the same message However I now discovered when I press the 'Detail Info'
button in toolsUI, I get a similar conversion error as reported for IDV (see attached).
thanks, it was a minor bug i have fixed now
The reason why I am interested in this data is that the WMO GTS system (for SYNOP, TEMP, SHIP, BUOY, etc) is migrating from the alphanumeric code formats to the binary formats (http://www.wmo.int/pages/prog/www/WMOCodes.html). The deadline was due this month but I believe it has been postponed a while. Regards, Reinoud
