Nitrogen dioxide (NO 2 ) is one important species in the tropospheric layer that has a contribution towards air quality. In urban areas in Indonesia, urbanization and growing industrial activities have increased rapidly, which may have affected tropospheric NO 2 . This study investigates the effect of green spaces and other environmental variables (e.g., temperature, city, distance from the equator) had on tropospheric NO 2 in over thirty (30) urban areas in Indonesia between 2007 to 2016. Data on land cover were obtained from Google Earth’s satellite imagery data, tropospheric NO 2 readings came from Metop-A, and information on temperature was obtained from the Terra MODIS satellite. Our results show an annual decrease in green space over 10 years in all urban areas except Surabaya. Multiple linear regression analysis also reveals that a decline in vegetation decreases tropospheric NO 2 significantly. Other influential environmental factors are surface temperature and distance to the equator. Despite a promising model being obtained from this study, adding variables is important to improve the forecasting.
