Abstract Aerosols have significant impacts on the climate changes by modifying the atmospheric radiative balance. It is essential to observe the spatial and temporal variations of the aerosol composition and optical properties. In this paper, we firstly show the global 3-D distribution of the aerosol composition and optical properties estimated from the space-borne lidar and imager. Furthermore, the shortwave direct radiative forcing of aerosols for the downward radiative flux density at the top of the atmosphere, and the aerosol impacts on the shortwave heating rate are investigated. In the last, the future satellite missions regarding to the lidar are introduced. |
