Bufr Decoding Software For Phones
Good afternoon Steve, typically such functionality is part of the message switching software (e.g. IBL Moving Weather is capable and contains such functionality). I don't know what is the situation in Tanzania and if they do use a message switching software but if so, it may be good to ask the vendor of their message switching system. Or maybe to ask their RTH for assistance?

All, There seems to some confusion between files and bulletins. As you know, it states in the Manual on the GTS that “ 2.3.3.3.1 The text of meteorological bulletins in binary representation shall consist of one single message. But there can be many BUFR messages in a file, as described on page II-15/23 and II-15/24 of the same Manual.
The options available are a) to treat each station’s observation as a subset, and create one BUFR message/bulletin with multiple subsets, or b) to put each station’s observation in its own message/bulletin and then combine the individual messages in one file. Option a) is only possible if the observations use the same encoding sequence (Section 3). In this case, if any delayed replication factors are also the same, the subsets can be compressed.

Dear all, I'd like to add that option b) is much more simple. Provided all BUFR messages have no start-of-message and end-of-message parts (i.e. They start with 'BUFR' and end with '7777') combining (under DOS) might be implemented by something like copy /b StartOfMssg +BUFR1 +BUFR2+.+BUFRn+EndOfMssg=NewBulletin where StartOfMssg should contain appropriate abbreviated heading. Stripping of start-of-message and end-of-message from individual messages is also not very complex. But making multi-subset BUFR from single BUFRs assumes at least their decoding and indeed in general is impossible when individual BUFRs use different encoding sequences.
It requires dedicated MSS.

Marian Majan 07:21. Dear Sasha, I believe such solution is not acceptable and not correct at all. If we are talking about BUFR bulletins, it contains. bulletin heading - TTAAii CCCC DDGGgg BBB. 0 - indicator section ('BUFR'). 1 - identification section. (2 -optional section).
3 - data description section. 4 - data section. 5 - end section ('7777') You can not simply strip heading, section 0 and section 5 and collect the rest (sections 1-4) and add BUFR and 7777 envelope. This can not be consider as a correct BUFR message and it can not be processed by most of softwares (e.g. BUFR ECMWF checker says END OF BUFR MESSAGE NOT FOUND; neither most of the message switching softwares won't be able to process such message as they check length of the message and search for 7777). What Simon refers to in the second option is to collect more messages in one file - so called file assembling.
You take a complete message, with its heading and all sections and put another message after the first one. Each message in the file has its own WMO heading. There are several formats specified for message assembling. But what Steve asked for is the first option (he mentioned BUFR file, but I believe he thought BUFR bulletin, because he wrote 'ie a file with just one set of headers that covers all the stations').
This so called 'message compilation' is done by repeating reports in the data section 4 - there are more data subsets inside and as Simon wrote, all reports has to use the same sequence of descriptors (which is Steve's case).

After reading what Marian answered and comparing it whit I´ve said previously, I guess I used the wrong term 'compilation'.
What I meant to say was the possibility to create a new BUFR bulletion using report from diferent input bulletins. For instance, from the original bulletin ISA01 SBBR and another one like ISAI02 SBBR or any other BUFR bulletin take 3 or more reports and compile a new bulletim with these three or more reports. May be the correct word to use to represent this process is 're-compilation'. Please correct me if I´m wrong. Dear Marian, Sorry for possibly poor explanation but I surely didn't suggest stripping 'BUFR' and '7777'. Enclosed are few examples of what I meant. They are operational BUFR bulletins with AMDAR data I recently dealt with.
They contain after a bulletin header a sequence of BUFR messages each starting with indicator section 'BUFR' and ending with end section '7777': length of message: starting line (?!):SOH, CR, CR, LF, nnn, heading: TTAAii CCCC DDGGgg BBB BUFR message 1: 'BUFR'. '7777' BUFR message 2: 'BUFR'. '7777' end of message. If individual incoming BUFR messages are surrounded by starting line, heading and end of message the latter need to be stripped. I'm not sure does this approach fully complies with GTS Manual (to my understanding it violates it. 2.3.3.3.1 The text of meteorological bulletins in binary representation shall consist of one single message). But it seems to be the easiest way to cope with the problem.
Approach a) assumes decoding of incoming individual messages and may be difficult to implement if not supported by existing MSS.

Simon From: Steve Foreman mailto: Marian Majan 23:20. Dear Sasha, thanks for the explanation, now I understand, by the start and end of the message you meant 'SOH' and 'ETX'. As you wrote, your example does not comply with WMO Manual 386. And it may and will be problematic for many WMO-compliant message switching systems. Message switching system usually contains message database, so it stores each received message separately. Tafseer ibn kaseer urdu pdf. Each message has to have its heading. The problem is not with 'disassembling' messages from your file.
But the second message does not have its heading. So if I take your file and process it with our message switching software, both messages are extracted and stored. The first one has correct heading IUAX01 EDZW 122252. But how should mss determine the heading of the second message? Our message switching system automatically generates heading for the second message and stores the message with this heading into its message database, but as the heading is generated it brakes all other operations with the message - e.g. Possible conversions and routing to other NMCs. I don't say solution as you use it for AMDARs is unusable, if all parties agree to use it in this way, they can.
If they handle it as a file and not as a message they can even route it correctly. But it is not compliant with WMO specifications and it will cause problems while processing by NMCs that do know nothing about it. And I believe we would like and we should avoid such solutions.
