At the same time, the atmosphere beyond the dust layer is warmed because of absorbing the LW radiation emitted by dust …
Webon cloud radiative forcing using a radiative transfer model along with satellite data analysis. By examining the influ-ence of Asian dust aerosols on the radiative forcing both at the TOA and the surface, this study should lead to a better un-derstanding of the interactions among dust aerosols, clouds and radiation. 2 Data and methodology WebThe aerosol radiative forcing at the bottom and the top of the atmosphere over China were obtained based on the long-term observations within SONET . It is determined that the aerosol radiative forcing at the top of the atmosphere and the surface both doubled during an aerosol event with a peak AOD of 0.6 in Central Europe .
Websimulations of dust LW forcing remain a challenging task because of the high spatio-temporal variation of dust properties [Myhre et al., 20031. Using satellite observations, several studies have attempted to estimate the LW radiative forcing of dust aerosols. For example, using broadband measurements from the Earth Radiation Budget
