Central data processing, archiving and dissemination node:

‐ 15 specialized data processing systems; ‐ operative and long‐term data archiving; ‐ data distribution system.

Additional Items 1) Risk of allocation of L­Band frequency 1.7 GHz to broadband

mobile communications. Roshydromet objects against the allocation of any part of radiofrequency band 1675 – 1710 MHz to broadband mobile communication. The band is necessary for data transmission from Russian meteorological satellites and will be most used in the nearest future.

2) Interference observed in soil moisture measurements at 1.4 GHz. Roshydromet doesn’t use this band now but intends to use it for MW sounding soil moisture and ocean salinity in future. Russian State Committee on Radio Frequencies permits to use the band 1400­1427 MHz for the following Radio Electronic Aids: ­ Earth exploration satellite service, ­ Radio­astronomy service, ­ Space research service. All these purposes are in need of passive receiving equipment which can’t prevent the soil moisture measurements from space.

3) Structure of Meteor­M basic instrument data transmitted via UHF band (1,7 GHz). English text of this structure is placed on Internet site of SRC “Planeta” at the address http://planet.iitp.ru/english/spacecraft/meteor_m_n1_structure_eng.htm

4) International cooperation. This year Roshydromet is preparing to host the 39 th meeting of CGMS in St. Petersburg.
