2. PRINCIPLES FOR THE ESTABLISHMENT OF THE EXCHANGE PROGRAMME FOR
OBSERVATIONAL DATA ON THE MAIN TELECOMMUNICATION NETWORK
The types of meteorological messages containing observational data to be exchanged on the
Main elecommunication Network are given below.
2.1 Type of information
(a) |
Surface observations on land and sea, including data from ships and buoys; |
(b) |
Upper-air observations including data from aircraft; |
(c) |
Climatological data; |
(d) |
Selected satellite data; |
(e) |
Seismic data (level 1), tsunami and other types of data as agreed. |
| |
|
| |
Note: Items (a) to (e) do not indicate priorities. |
2.2 Stations/areas from which reports should be included in the bulletins that are to be
exchanged
The list of stations from which reports should be included in the bulletins that are to be
exchanged are established as follows:
(a) |
All surface stations. The SYNOP reports from land stations exchanged on the MTN shall include at least
Sections 0 and 1 of the SYNOP code form. As an interim measure, Section 3 of the SYNOP code form
shall also be included in the global exchange on the MTN; |
(b) |
All stations (on land or at sea) making radiosonde/radiowind observations; |
(c) |
All aircraft; |
(d) |
All climatological stations; |
(e) |
All oceanographical stations. |
3. RESPONSIBILITIES OF CENTRES LOCATED ON THE MAIN TELECOMMUNICATION
NETWORK FOR THE EXCHANGE AND DISTRIBUTION OF PROCESSED INFORMATION AND
SATELLITE DATA
The exchange of processed information and satellite data on the MTN should be arranged
between the MTN centres to meet the requirements of the WWW centres.
Figure 1 — Plan for routeing observational data on the Main Telecommunication Network
Note: The responsibilities of centers and routeing arrangements for the exchange of processed information on the MTN are the same as for observational data. |
