RTH SOFIA
• RTH - Sofia’s zone of responsibility as appointed to the regional
meteorological telecommunication plan are:
Albania, Bulgaria, Cyprus, The Former Yugoslav Republic of Macedonia,
Romania, Serbia and Syrian Arab Republic.
• RTH - Sofia successfully migrated to the RMDCN IP/VPN MPLS (OBS)
on 18.06.2007
• RTH – Sofia use TCP/IP as the data transport protocol, with FTP, to all
connections.

RTH SOFIA
In the latter years RTH Sofia work successfully on the connection of the
NMCs of its zone of responsibility and some NMCs of Balkan states into
the GTS through RTH Sofia.
NMCs in Tirana (Albania), Podgorica (Montenegro) and Sarajevo (Bosnia
and Herzegovina) were connected into the GTS. The connections were
accomplished by WMO VCP Coordinated Projects implemented in the
relevant country to solve the significant problems of some NMCs to fulfill
their requirements for international exchange of data and products
keeping balance of costs, availability and functionality.
The connections provide exchange of data/products on the GTS through
RTH Sofia based on public Internet and VPN IPSec technology. However
the realized Projects provide an effectiveness exchange on the GTS .

Problems
About connection to the GTS
√ There is a NMC not connected to GTS yet:
NMC Damascus
NMC Damascus has a problem in receiving data through AFTN. Due to high cost of the GTS
connection’s offering they have not plan about.
Proposal:
Based on the
recommendation of RAVI WG PIW, fifth session
а VCP Project :
VPN/IPSec over Internet connection between RTH Sofia and NMC Damascus
to be announced.
√ NMC Larnaca uses low speed connection to GTS via NMC Athens
The attempt of RTH Sofia could be apply in NMC Larnaca for the VPN/IPSec over Internet connection
between RTH Sofia and NMC Larnaca by the implementation of a relevant project;

TRAINING
During the Project implementations all NMCs expressed request for an additional training
about the new installed systems and technologies, the current GTS and it in the near, data
formats and so on. Their requests are reflected in the relevant final reports sent to WMO.
In regard to this I suggest a workshop to be carried out in Sofia under assistance of WMO
where the experts from RTH Sofia to lead the training course (in practice as well) by
programme confirmed to WMO.
OTHERS
The relevant Vol. C1 are not updated for some countries of the RTH Sofia’s zone of
responsibility. In result
the list of stations for monitoring is not correct and the results
from the monitoring, too.
