hydrometeorological agencies: national (51%), regional or subnational (1%), both national and regional (42%), and neither national or regional (6%).
Also, about 40% reported the need for strengthening or modernization of hydrometeorological observing networks in general or specifically for flood forecast- ing purposes (although the review noted that improvement programmes were already underway in a significant number of countries).
� Ground-based observations from several thousand raingauges transmitted via Data Collection Platforms to the GOES East and GOES West geostationary satellites for initial processing by the Hydrometeorological Automated Data System HADS (http://www.weather.gov/oh/hads/WhatIsHADS.html)
Table 3.2 summarises the main options which are available for the telemetry of hydrometeorological data.
