The automated station constantly updates data on wind speeds and directions, rainfall, dust, ozone and air quality. Its equipment is connected to the city’s monitoring system, and all indices are publicised on the municipal People’s Committee’s portal.
At the same time, the station allows detailed study on pollution and sources of pollution.
Earlier, the French-based ENVEA, a renowned manufacturer in the field of environmental instrumentation, installed ten air quality monitoring stations in the city under the AFD/Airparif technical support project.
The air quality monitoring solution installed in Hanoi has been completely provided by ENVEA and includes 2 reference pollution monitoring stations measuring gases Ozone (O3), Carbon Monoxide (CO), Sulfur Dioxide (SO2), Nitrogen Oxides (NO, NO2, NOx), Particulate Matter (PM 2.5 and PM 10), as well as 8 Cairpol sensor-based microstations to measure NO2, CO and particulates. All 10 stations being equipped with data acquisition & handling systems, the measured parameters are automatically transmitted to the central server, where the XR® software ensures the supervision and data management. The XR calculates (data scaling, correction, linearization, normalization) and aggregates the resulting data over different time periods. It also follows-up and controls all measuring devices (analyzers, data acquisition systems, meteorological sensors, calibrators, communication systems…) with multi-window representation for data display (raw, means, trends, graphs…), real-time graphic followups, interactive set-up, calibration & automatic results monitoring, remote testing of interfaces, etc…
Major event for the city, the Network’s inauguration has been widely covered by the local and international media, as well as on the National television VTV :
The city’s pollution monitoring network with data generated by the 10 AQMS stations installed, being centralized and published online on the Government’s website http://moitruongthudo.vn/ The page provides AQI (Air Quality Index) over the last 24 hour period as well as pollutant concentration for each station.
At the inauguration ceremony, French Ambassador to Vietnam Bertrand Lortholary said Vietnam and France see environment as prioritised cooperation. Activities carried out by Hanoi and Ile-de-France have contributed to this strategic target.
The air monitoring station at the French Embassy is a vivid illustration for the bilateral environmental collaboration, he said, adding it is also a highlight in the Hanoi – Ile-de-France partnership, especially on the occasion of the 30th anniversary of cooperation between the two localities.
At the event, the French Embassy displayed the “HoanKiemAir” 3D model, illustrating the relations between traffic and pollutant emissions in Hanoi.
The capital city now has 16 environmental monitoring stations, including 11 automated air quality monitoring stations, and five water monitoring stations. It targets 95 air quality monitoring stations by 2020 to have comprehensive evaluation system so that solutions will be mapped out to reduce pollution.
