| Abstract | In dry season, forest fire is significant source of pollution in the northern part of Thailand affects air quality in the area. This study applied satellite data that monitoring of CO and fire hotspots in conjunction with ground monitoring data collected from 9 stations during forest fire episodes. Data from satellite remote sensors, MOPITT total column, MODIS AOT and MODIS hotspot, were compared with ground-based measurements to examine the impact of forest fire on air quality and the capacity of satellite-based measurement for period of February-April, 2008 -2010. The correlation coefficients verified that CO and PM10 were dependent on the forest fire hotspot especially in the rural areas with R = 0.59 for CO and R = 0.65 for PM10. The correlation between ground-based measurement and satellite-based monitoring were high during forest fire episodes with R = 0.59. Multivariate analysis tool of principal component analysis was implemented and reveal that PM10 and CO were highly associated with the number of forest fire spot while wind speed, temperature, relative humidity, pressure, cloudiness, and mixing height had influence on the concentration of air pollutant in the study area. Two forest fire episodes were selected based on ground PM10 and CO concentration. The spatial distribution of MOPITT CO total column and MODIS AOT were analyzed. The first episode, CO and AOT plume transported from southwest to northeast part of the study area. The second episode the plumes dispersed from west to east of the area. Satellite products provide helpful insights into air pollution monitoring. To improve the comparative data between ground and satellite, CO vertical profile should be conducted at some ground-based stations. Further in-deep analysis of the relationship between MOPITT CO, MODIS AOT and hotspots should be conducted for a long period and over different areas in SEA to examine the capacity of satellite-based data in monitoring long range transport phenomenon in the region and beyond. |
