Abstract

Abstract:

We performed a comprehensive experiment in Beijing-Tianjin-Tangshan region during March 2012. The aerosol direct radiative forcing was explored using the radiative transfer model SBDART based on ground-based and satellite remote sensing data. The measured aerosol optical parameters indicated that there were a large number of fine particles in the atmosphere; aerosol's effect of extinction in solar radiation was evident; aerosol scattering was large; and the forward scattering was strong. The average aerosol direct radiative forcing values were (-6.58±5.06),(-13.65±11.51),and (-11.68±7.72)W/m² on the top of atmosphere,(-30.14±13.21), (-39.11±20.5),and (-28.06±13.34)W/m² at the surface,and (23.56±9.50),(25.46±12.93),and (16.38±8.23)W/m² in the atmosphere at Beijing, Tanggu, and Tangshan,respectively. Aerosol cooling effect to the surface and top of atmosphere and aerosol heating effect to the atmosphere were strong, which could cause atmospheric temperature inversion and then suppress the pollutant dispersion. At Beijing site, aerosol radiative forcing was relatively small, but aerosol radiative forcing efficiency was the largest among the three sites, which was mainly because the single-scattering albedo of aerosols was the smallest at Beijing site.

Key words: aerosol direct radiative forcing, aerosol optical properties, Beijing-Tianjin-Tangshan region, SBDART
