Correlation between Ground-based Particulate Matter Concentration and Aerosol Optical Depth during Forest Fires in Palangkaraya City
Keywords:Aerosol Optical Depth, Forest Fire, Palangkaraya City, Particulate Matter
Forest fire is a natural disasters that can be caused by both nature and humans. Forest fires can cause a decrease in air quality caused by particulate matter from combustion. Daily particulate concentrations are monitored from meteorological stations in Palangkaraya City. This study aims to see the correlation between ground data and AOD data. The relationship between particulate concentrations in surface data monitored at the Tjilik Riwut meteorological station, Palangkaraya City, and Aerosol Optical Depth (AOD) data obtained using the Google Earth Engine (GEE) can be seen from the correlation coefficient and determination coefficient during the rainy season, dry season, and during the rainy season. forest fires from 2018 to 2019 in Palangkaraya City show a low relationship indicated by the correlation coefficient interval of 0.40. During the period of forest fires the highest correlation coefficient of AOD and particulates (PM2,5 and PM10) showed a low correlation with a maximum value of 0.25 in 2018 while, during the period of no forest fires the maximum correlation coefficient value was 0.40 in 2018 period. This shows that the correlation between AOD and particulate matter (PM2,5 and PM10) is better in periods non forest fires. Factors that can interfere with the AOD value are cloud cover and other meteorological factors such as humidity, solar radiation, and others.
