Air Pollution Monitoring and Forecasting System (PM2.5) for Vietnam

• Technology

The PM2.5 dust pollution monitoring and forecasting system uses artificial intelligence models built on multi-source data, including meteorological data, land use data, satellite data, and multi-year station data.

• System Functions:

  • Monitoring PM2.5 dust concentration (daily average) in near real-time.
  • Forecasting PM2.5 dust concentration (daily average) for the next 1-3 days.
  • Spatial resolution detailed down to each 1 km² area, allowing for monitoring and forecasting information at the district and province/city levels.
  • Supporting tools for display, detailed information viewing, analysis, statistics, and sharing of monitoring and forecasting data.
