Support Necessary for AMY-2008 in Bangladesh
Several Components such as
Magnetron are necessary for Continuous Radar Operation
RS Balloons for Intensive observation, if necessary
Access of Real-Time Satellite/TRMM data
Target:
Preparation of composite map for rainfall using rain-gauge, radar and satellite data, which will be utilized for the real-time flood monitoring and as the input of water modeling for flood forecasting.
