The CBS Advisory Working Group recommended that a special table should be added to the monthly letter to report changes of the present status of implementation of observing programmes of SYNOP, TEMP and PILOT reporting stations. You will note, therefore, that a new item, number 7, "Feed-back from Members to the Secretariat on any changes in the observing network" has been added to Annex 1 - Global Observing System.
Your co-operation in ensuring that the above information reaches the appropriate operational units of your service is greatly appreciated. If you wish to receive additional copies of the monthly circular letter, please inform the Secretariat accordingly.
Yours faithfully,

Notification from Botswana
That the new station 68040 LETLHAKANE will for the time being operate daily from 0300 to 1800 UTC due to staffing constraints. It is however intended to bring it to a 24-hour watch system as soon as possible.
This station has been included in the Botswana meteorological bulletin as from 1 September 1992.
Notification from Australia
1 naes i li h v' 'm 'n li
That Tasmania will introduce one hour daylight saving (summer time) from 1600 UTC 3 October 1992 until 1500 UTC 27 March 1993 and Victoria, New South Wales, Australian Capital Territory and Southern Australia from 1600 UTC 24 October 1992 until 1500 UTC 6 March 1993.
Western Australia, Queensland and Northern Territory will not be implementing summer time.
Surface observations at stations in those states implementing summer time will be made one hour earlier.
Surface observations at stations in Western Australia, Queensland and Northern Territory will continue on the present schedule.
Upper-air stations in Tasmania will make ascents one hour earlier at 161 5, 221 5, 041 5 and 101 5 UTC commencing on 3 October 1992 and ceasing on 27 March 1993.
All other upper-air stations in Australia will make ascents one hour earlier at 1615, 2215, 041 5 an 101 5 UTC commencing on 24 October 1992 and ceasing on 6 March 1993.
Upper-air stations in Western Australia currently perform a routine ascent a t 1615 UTC throughout the year. No change will therefore be made to the release time of this ascent due to daylight saving.
Other stations under Australian control will adopt the following schedules:
~~~~~~ ~
94299 Willis Island .......................... will follow Queensland practice
94995 Lord Howe Island ................ ) 94996 Norfolk Island ............... .......) 94998 Macquarie Island ................. entire observation programme one hour earlier
96996
will follow New South Wales practice
Cocos Island ................ : ........ will follow Western Australian practice
Surface and upper-air programmes of Antarctic stations operated by Australia remain unchanged.

Data from moored and drifting buoys are collected via geostationary and polar orbiting satellites respectively. Meteorological reports from moored buoys using FM 13-IX SHIP code are distributed on the GTS from the Direct Readout Station located in Vancouver, B.C. Reports from drifting buoys are received at the ARGOS Local User Terminals in Edmonton and Toronto and distributed on the GTS using the FM 18-IX DRIFTER code.

u a e s F - k f r M n n in the obse wing nehnrork In view of the difficulties experienced a t present in identifying non-implemented observing stations or implemented stations which are closed or suspended for a certain period, or stations making observations but not reaching their NMCs, the ninth session of the CBS Advisory Working Group recommended that a special table be added to the WWW monthly operational letter to serve as feed-back from Members to the Secretariat on any changes of the present state of implementation of observing programmes of SYNOP, TEMP and PILOT reporting stations.
The special table, accompanied by explanatory notes (see Appendix, pages 1 and 2) is attached as an appendix to this annex. Members are urged to fill in this appendix, as and when appropriate, and to return it to the Secretariat before the 1st of each month to enable changes to be included in the next monthly letter.

1. Separate tables should be prepared for global exchange and regional exchange respectively. These tables should contain information concerning any changes of the present state of implementation of observing programmes of SYNOP, TEMP and PILOT reporting stations given in Attachment 1-4 of the Manual on the GTS, Volume I for global exchange and, as applicable, Attachments AF-I, Al-1, SA-1 , NA-1 , PS-1 and EU-1 of the Manual on the GTS, Volume I1 for regional exchange.
2. For entries in these tables, the following should be taken into account:
(a) In the column "Station index number", the index number (Iliii) of each station should be entered in case of any changes in the observing programmes of the stations;
(b) In the column "Bulletin identification", the TTAAii CCCC of the abbreviated heading of the meteorological bulletins which contains reports from the station should be inserted;
(c) In the column "Implementation of observing programme", "X" for implementation and 'I-" for non- implementation should be inserted as appropriate. In order to easily identify changes in the programme, this should be marked in red;
(d) In the column "Alternate observing station", the index number (Ilii) of an alternate observing station should be inserted in case another station is available with a view to filling gaps which are caused by suspension of observing programmes of the original station;
(e) The required information concerning the observing programme of the alternate station should be inserted in the next horizontal line of the original station;
(4 In the column "Remarks", reasons of temporary suspension of observing programmes and an expected date of resumption of the programmes should be given as far as possible. Non-standard collection and/or distribution times should also be included.
3. These tables should be sent to the Secretariat before the 1st of the month for inclusion of the changes in the monthly operational letter, as appropriate.

6.4 GMDSS broadcasts
The Global Maritime Distress and Safety System (GMDSS) of IMO entered into force on 1 February 1992. The new WMO high seas marine broadcast system for the GMDSS that operates through the International SafetyNET Service of INMARSAT, was also implemented from this date. This new system will operate in parallel with the existing broadcast system (through coastal radio stations) until 1 February 1999. The transmission schedule for the full GMDSS service broadcasts of routine weather bulletins (including warnings) for the high seas is given in Table 1 for the different ocean areas. The INMARSAT Coast Earth Station (CES), as well as the actual satellite through which these bulletins are transmitted are also indicated (e.9.. AOR(E) = Atlantic Ocean Region Satellite (East), etc.).
For some ocean areas, the full GMDSS service is not yet implemented because of technical reasons related to access to the appropriate CES. For these areas, an interim urgent meteorological warning information service has been put in place. The transmission schedule for this service is given in Table 2.
