The regional radiative forcing of three dimensional aerosol distribution characterized by CALIPSO

The shortwave radiative forcing affected by the aerosol vertical distribution over northeast Asia is investigated using the rapid radiative transfer model shortwave code with aerosol observation data from the Cloud-Aerosol LIDAR with Orthogonal Polarization (CALIOP), carried on the Cloud-Aerosol LIDAR and Infrared Pathfinder Satellite Observation (CALIPSO) satellite. The optical properties of atmospheric aerosols with spatial, temporal, vertical, and spectral resolutions are characterized by CALIOP space-born LIDAR observation, which can help to demonstrate radiative transfer process at each altitude. The results indicate vertical distributions observed by CALIOP are seen to vary with season because of dust or smoke at layered structures. The vertical distributions of those aerosol profiles dramatically influence the shortwave flux and radiative forcing profiles. This study also suggests that CALIOP measurement-based heating rate profiles provide useful data for indirect estimates of aerosol-climate interaction studies.
