National Research Council of Thailand (NRCT) has been funded and support to establish the network of PM2.5 low cost sensors for Thailand by consolidating real-time data from each installation site in which could be shown in terms of hourly average (ug/m3), daily average (ug/m3) and also Air Quality Index that calculate by PM2.5 (PM.5 Th-AQI) Moreover, we applied WRF-Chem to forecast PM2.5 and PM2.5 Th-AQI for three days. In addition, we tracked the NASA earth observing information of active fire-hotspot both in MODIS and VIIRS that could identify GPS location and land-use data. Hence, this informative data could be used for rapidly, accuracy and effectively monitoring and warning during the air pollution impact crisis in Thailand.
