On May 17 in Ha Noi, the Ministry of Natural Resources and Environment held a conference to unveil the National Hydrometeorological Monitoring Station Network Plan for 2021-2030, with a vision toward 2050.
The plan builds upon the National Natural Resources and Environmental Observation Network Plan results for 2016-2025, with a vision to 2030. The plan aligns with practical needs to maximize achieved successes and address shortcomings in the existing hydrometeorological (hydrometer) station network.
According to Mr. La Duc Dung, Deputy Director General of the Viet Nam Meteorological and Hydrological Administration, the new plan introduces breakthrough elements compared to the previous period. These enhancements aim to reflect current realities and meet assigned objectives.
Notably, the network planning is now based on observation elements rather than station classifications, as previously done. This approach ensures a balanced density of observation stations—neither excessive nor insufficient—guided by advanced, automated observation technologies modeled after those in developed countries. The goal is to meet increasing demands for hydromet data to support forecasting, early warnings, and socio-economic development across various stages.
The plan incorporates findings from published research, recommendations from the World Meteorological Organization (WMO) on station density, and studies of advanced global station network models. Practical conditions have been factored in to determine scientifically sound, cost-effective station density and placement.
Under the new classification system, stations are categorized into two types: Basic stations – equipped to observe all elements, staffed with operators; and Standard stations – designed for observing selected elements, fully automated, with no operators. This reclassification lays the foundation for advancing automation, targeting 100% automation of standard stations. As a result, observation capabilities will be enhanced, operational costs will be reduced, and human resources and land use will be optimized.
Additionally, the plan prioritizes addressing data gaps and focusing on areas frequently impacted by natural disasters and climate change risks.
