| Summary: | Abstract Exploring various properties of aerosols can help to better understand global climate changes, emissions, and environment. In this study, a synergy observation experiment from sun photometer and Lidar was carried out to reveal aerosol optical properties and direct radiative effect (DARE) in Central China from the novel perspective of aerosol components. Our results showed that the annual mass concentration of black carbon (BC) was low (2.49 mg/m2), but having large heating effect with the DARE of 9.27 W/m2 at the top of atmosphere. The brown carbon was found highest in summer (0.52 mg/m2) and its annual DARE was 0.10 W/m2, close to the average of China. Additionally, retrieved columnar concentration of BC had the same magnitude with the MEERA‐2 product, and showed better results at the surface (R = 0.56) because the considering of aerosol vertical profiles. This study showed the significance of exploring expanded aerosol information from observations. |
