Seasonal Variations Of Nitrogen Dioxide And ITS Comparison With Emission Inventories

Abstract

The objective of this study was to analyze seasonal variation of tropospheric NO2 in Indonesia compared to NOx emission and precipitation. Using satellite data, it was found that western of Indonesia had more NO2 than eastern. We then classified three regions based on high NO2 concentration values. The result was at dry season (less precipitation), NO2 reached maximum and vice versa while in wet season (more precipitation), NO2 peaked minimumHal.21-2
