Center for hydro - meteorological & Environmental station network
(the Hymenet)
And
hydrological, meteorological & Environmental station network
The HYMENET
• Position: The HYMENET is a functional body under National Hydro-Meteorological Service of Vietnam, Ministry of Natural Resources and Environment • Function: Technical supervision & management the hydro-meteorological & environmental (water & air) stations network and all the observation activities in order to provide sufficient & adequate data for hydro-meteorological forecasting, water- utilization, disaster mitigation, socio-economic development of the country.
The Network
Meteorological stations network • Total 176 stations, divided into 3 classes
Class 1: Weather watch: 24/24 hrs Observation of: Wind (direction & speed), Rain
fall, Air pressure, Air Temperature, Humidity, Sunshine, Evaporations, Land Temperature (ground and deep layers); Cloud, Visibility, Ground conditions, Radiation (at some stations).
Data collection & transmission: 8 times/day Class 2: Same as class 1, but not doing the
observation of radiation, air pressure (at some stations).
Data collection & transmission: 4 times/day Class 3: Same as class 2, but not doing the
observation of air pressure. Data transmission
Total: 176 stations
• Class 1: 58 • Class 2: 70 • Class 3: 48 • Synoptic : 131 • Climatic : 43 • Radiation : 13 • Agro. met. : 27 • Belong to Global
Observing System: 25
