Abstract

Diurnal variabilities of aerosol properties are important to quantify its impact on public health and climate at high temporal resolution. In this study, we firstly map the hourly aerosol optical depth (AOD) in East Asia using satellite observations from the Deep Space Climate Observatory (DSCOVR). Secondly, we compare our result with the ground AOD observations from AERONET. Both datasets show increasing trends during a day and a higher increase in eastern China. We also show a good correlation between AOD and bottom-up emissions. Our results shed light on future studies to investigate the diurnal variabilities of aerosol from geostationary pollutant observation satellite.
