Abstract

High quality monitoring of particulate matter 2.5 (PM2.5) data observations that covers entire Indonesia are crucial for air pollution management. Aside from its negative effects on health, its relationship with climate change also needs to be concerned. PM2.5 data from Copernicus Atmosphere Monitoring Service (CAMS) has been broadly used to complement the ground-based observation of PM2.5. This study aims to assess the validation of the CAMS based on the available ground-based measurement of the air quality indicator, PM2.5, over the Indonesia region. The validation includes 27 ground-based measurements of PM2.5 over Indonesia during the very recent years, 2021 - 2022. This study pursued the validation of the PM2.5 of CAMS products using the model statistical performance, including Mean fractional bias (MFB) and mean fractional error (MFE). The results of the temporal pattern of the PM2.5 of ground-based measurement and CAMS have varied variations. However, the results show that 89% from all the study locations have met the model performance goal. Additionally, all the study locations also have met the model performance criteria. Finally, this study proved a good performance of PM2.5 of CAMS products over Indonesia region.
