Abstract
Indonesia suffers from high annual vehicle ownership growth, resulting in worsening urban air quality. Nitrogen dioxide (NO2) is one of the combustion products of vehicles which needs to be monitored. Unfortunately, few cities have air quality monitoring stations, thus there is an immediate need to tackle this issue. One way to do so is by utilizing remote sensing via satellite. In this study, we utilized a satellite OMI (Ozone Monitoring Instrument) to read patterns in gaseous NO2 concentrations. This work was assisted by a Geographical Information System (GIS) program, which used the results from the satellite to create images. Data validation was conducted by comparing the results from the satellite images in the form of color pixels with the results obtained from monitoring stations in Jakarta and Surabaya via linear regression. The results showed a weak correlation. Further research should introduce additional variables to improve accuracy.
