Spatial distribution of PM10 derived from Landsat 8 imagery in Bandung, Indonesia

Abstract

Air pollutant of PM10 concentration over Bandung City was estimated based on satellite imagery. The imagery was acquired by Landsat -8 on 22nd May 2019. The methodology implementation were started with pre-processing includes geometric correction, radiometric calibration to converted of digital number into surface reflectance values to estimated PM10 concentration. For calculated the algorithm of PM10 need the coeficient aerosol optical depth (AOD) was using from AERONET. The results showed that the estimation of PM10 distribution through satellite imagery in Bandung in the year of 2019 in average 36.18 μg/m3. According to Air Pollution Standard Index from that average Bandung city is still in healthy category of PM10 concentration. The calculated data on PM10 were also compared with ground measurements of PM10 data estimated from different locations of Bandung for validation and a linear relationship was established between them having a moderate positive relationship with the correlation coefficient value of 0.6187.
