Meteorological Data Communication System
.. Surface and upper air data for forecasting is exchanged under GTS fRTHNDlhiIdifrom RTH New Delhi, India.
Data Receiving from RTH New Delhi .. Real time data from 15 syypypnoptic station through ( HFSSB) radio or Code Division Multiple Access (CDMA) wireless modem used for weather forecast & internal Exchange.Exchange.
Real time data receiving from Synoptic Station .. Since 19981998,, MFD receive various meteorological information through SADIS byyy World Area Forecast Centre (WAFS) located Barcknail, LondonLondon
Met .Information though SADIS Meteorological Data Communication System
TCP/IP Communication Future Plan
.. Installation of AWS in all synoptic stations during this year 2010 under SAARC_STORM project. .. One Doppler Weather Radar probably next year .. Two GPS Sonde Stations .. 16 telemetry rainfall stations will be installed in model basin. .. 5 telemetry water level stations will also be installed in the same model basin. .. WRF model are to be run this year for improve weather forecast as well as flood forecast Thank Y ou All f or Ki nd Att enti on
