The effect of sulfate aerosols on cloud microphysical and optical properties has been studied using field measurements from a rural mountaintop location at the Mt. Mitchell State Park in the southeastern U.S. The sulfate concentrations were greater during 1993-97 than during 1986-89. Cloud albedo...
Models used to estimate direct and indirect effects of aerosols employ a variety of representations of such cloud-borne particles. Here we use a global aerosol model with a relatively complete treatment of cloud-borne particles to estimate the sensitivity of simulated aerosol, cloud and radiation ...
Although many models now include SOA, any overall estimate of the direct and indirect effects of these aerosols is still lacking. This paper makes a first step in that direction. The model is applied to estimate the direct and indirect effects of SOA under simulated year 2000 conditions. The ...
Laura M. Hinkelman, JISAO/Univ. of Washington, Seattle, NY; and S. Kato and M. Ovchinnikov Recorded presentation Estimation of aerosol direct and indirect effects requires accurate knowledge of aerosol properties both away from and in the vicinity of clouds. Currently, aerosol optical depth at ...
Rachel L. Storer, Colorado State University, Fort Collins, CO; and S. C. van den Heever and G. Stephens Recorded presentation Aerosols are known to have both direct and indirect effects on clouds through their role as cloud condensation nuclei. This study examines the effects of differing ...
The main goal of this paper is to evaluate the impact of considering the direct radiative effect of aerosols in ALADIN-HIRLAM short-range weather forecasts over Europe using input from different aerosol datasets. Climatological aerosol data from TEG97 and from the more up-to-date Max-Planck-Insti...
Aerosols can alter atmospheric stability through radiative forcing, thereby changing mean and daily extreme precipitation on regional scales. However, it is unclear how extreme sub-daily precipitation responds to aerosol radiative effects. In this study, we use the regional climate model (RCM) Consortiu...
Radiative effects of natural aerosols: A review In recent years, there has been a substantial increase in interest in the influence of anthropogenic aerosols on climate through both direct and indirect e... S Satheesh,Moorthy, KK - 《Atmospheric Environment》 被引量: 672发表: 2005年 Variability...
It is to be expected that atmospheric aerosols significantly impact upon the climate system by changing the energy balance of solar and thermal radiation (Intergovernmental Panel on Climate Change, 2001). Soil-derived mineral dust contributes significantly to the global aerosol load. Estimates of global...
Climate effects of dust aerosols over East Asian arid and semiarid regions It means that aerosols of East Asian dust can influence the cloud properties not only by acting as cloud condensation nuclei and ice nuclei (via first ... J Huang,T Wang,W Wang,... - 《Journal of Geophysical ...
