explanations

For an explanation of the common elements in most records, see ( add link to page containing Eizi's snippet on key fields, which will hopefully also include an explanation of a) citedResponsibleParty / CI_ResponsibleParty;
and possibly also (if group agrees)
b) an explanation of a rolling time-range (eg 1 month backwards, relative to now), by using
temporalElement / EX_TemporalExtent:
extent / TimePeriod :

If the above 2 aren't explained in a separate webpage, then add an explanation here.

The key differences, in the record below, compared with the other example records for WMO SYNOPTIC MDG_Synoptic and AVIATION MDG_Aviation Bulletins, is mostly just the field content which is specific to the CLIMAT product. That is: the abstract, the keywords, and the extent.

examples

Please note: the example "CLIMAT" record below is given for example purposes, and may not be the same as operational records.

  abstract: ---- A CLIMAT bulletin is for the latest month only, and began being provided in 2005.
CLIMAT bulletins are delivered to the GTS between the 5th and 8th day of the following month.
CLIMAT bulletins include CLIMAT reports for about 10 stations, and provide averaged monthly values (of daily averages of raw data) for each station, for the preceding month.

This CLIMAT bulletin is encoded as TAC (Text-encoded), and follows the FM 71 encoding specification (FM 71 is for CLIMAT -a report of monthly values from a land station).
(Refer to WMO No.306 - Manual on Codes for the definition of WMO international codes)

The CSAU01 TTAAii Data Designators decode as:
T1 (C): Climatic data.
T2 (S): Monthly means (surface).
A1A2 (AU): Australia.
(2: Refer to WMO No.386 - Manual on the GTS - Attachment II.5)

A brief cribsheet of data parameters, data format and code decryption is under "Supplementary Info".
Data Parameters are also summarised under "Keywords".

This bulletin (covering the month previous to the bulletin's release) collates reports from 11 stations:

Darwin airport (WMO Station#: 94120; BOM stationID 014015), Tindal RAAF (WMO Station#: 94131; BOM stationID 014932), Gove airport (WMO Station#: 94150; BOM stationID: 014508), Weipa aero (WMO Station#: 94170; BOM stationID: 027045), Broome airport(WMO Station#: 94203; BOM stationID: 003003), Halls creek airport (WMO Station#: 94212; BOM stationID: 002012), Tennant creek airport (WMO Station#: 94238; BOM stationID: 015135), Burketown airport (WMO Station#: 94260; BOM stationID: 029077), Cairns aero (WMO Station#: 94287; BOM stationID: 031011), Townsville aero (WMO Station#: 94294; BOM stationID: 032040), and Willis island (WMO Station#: 94299; BOM stationID: 200283).

  supplementalInformation: Data parameters and format decoding is explained in "Practical Help for Compiling CLIMAT Reports (2009), from http://www.wmo.int/pages/prog/gcos/Publications/GCOS-127_EN.pdf
The ISCK01 bulletin is collection of CLIMAT reports containing the same content as CSAU01 (though with additional data), but is in BUFR format. It is also available from AMMC.
