• 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 SOFIARTH SOFIA NIMH, Bulgaria
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 .

About connection to the GTS About connection to the GTS
√ There is a NMC not connected to GTS yet: NMC DamascusNMC 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.
ProposalProposal::Based on the recommendation of RAVI WG PIW, fifth sessionrecommendation of RAVI WG PIW, fifth session
а VCP Project :
VPN/IPSec over Internet connection between RTH Sofia and NMC Damascus VPN/IPSec over Internet connection between RTH Sofia and NMC Damascus

√ 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 connectionThe attempt of RTH Sofia could be apply in NMC Larnaca for the VPN/IPSec over Internet connection

TRAININGTRAINING
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.
OTHERSOTHERS
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.
