Vietnam applies satellite data to monitoring air quality
Hanoi (VNA) – A workshop on the application of satellite
data in monitoring pollution and research was held in Hanoi on December 1 as
part of the projects "Join hands for clean air” and “Improving
air pollution monitoring and management of Vietnam with satellite
PM2.5 observation”.
The event was jointly organised by the Vietnam Live and Learn Centre for
Environment and Community, the University of
Engineering and Technology under the Vietnam National University – Hanoi (VNU-UET), the Vietnam Clean Air
Partnership (VCAP) and
the “Tia Sang” magazine of the Ministry of Science and Technology.
In recent years, the situation of PM2.5 fine dust in Vietnam
has been studied and published in reports and scientific journals by State
management agencies, universities, institutes and scientists as well as a number
of social organisations.
However, reports and studies remain limited in terms of data
sources due to the lack of monitoring data and exploitation of open data
sources from satellites or sensor stations.
In
this context, a report on PM2.5 fine dust matter
in Vietnam in the 2019 -2020 period using multi-source data was
published, giving a more complete picture of air pollution in both space and
time. This was the first report that provides information on the situation of PM2.5
fine dust in all localities nationwide with data collected and analysed by standard
monitoring stations, sensors, and satellites.
Based on the report’s findings and referring to international experience, experts
discussed and proposed specific recommendations such as the application of multi-source
approach and computational model data from satellite images to monitor air quality, and development of detailed distribution maps
of PM2.5 fine dust in districts and townshíp in provinces and cities affected by PM2.5
fine dust pollution,
They
also underlined the need to strengthen air quality monitoring stations meeting the
State’s standards in localities across the country./.
