Abstract : Coronavirus disease 2019 (COVID-19) has been linked to exposure to air pollutants and climate conditions. The purpose of this study was to examine the correlation between COVID-19 mortality in Jakarta, Indonesia and fine particulate matter (PM2.5), carbon monoxide (CO) exposure, and climate variables (temperature, sunlight hours, humidity, precipitation, and wind speed). Meteorology station measurements of PM 2.5, CO concentrations, and climate conditions from May to August 2021. The second peak of COVID-19 infections happened in Indonesia at that time. Using COVID-19 daily mortality data and meteorology data, the linear regression test was used to evaluate the impact of ambient temperature and PM2.5 on COVID-19 mortality. Temperature and PM2.5 have been linked to COVID-19 mortality. An increase of 1 µg/m3 in PM2.5 concentration will result in an increase of 1.57 deaths. A minimum temperature increases of 1°C reduces 11.8 death cases. These variables may be taken into consideration when creating policy intended to regulate and stop the spread of new coronavirus chains in tropical nations.
