Although long considered to be of marginal importance to global climate change, tropospheric aerosol contributes substantially to radiative forcing, and anthropogenic sulfate aerosol in particular has imposed a major perturbation to this forcing. Both the direct scattering of shortwavelength solar radiation and the modification of the shortwave reflective properties of clouds by sulfate aerosol particles increase planetary albedo, thereby exerting a cooling influence on the planet.

Aerosols, Clouds, and Climate Change
Earth's climate is thought to be quite sensitive to changes in radiative fluxes that are quite small in absolute magnitude, a few watts per square meter, and in relation to these fluxes in theExpand
Climate response to radiative forcings by sulfate aerosols and greenhouse gases
The annual, global mean radiative forcing for the troposphere-surface system has been used to rank the global warming influences of atmospheric trace gases. The approach was also used recently toExpand

Aerosol and greenhouse gases forcing: Cloud feedbacks associated to the climate response
If the climate impact of the increased atmospheric concentration in greenhouse gases has received a very large attention, the increased atmospheric loading in anthropogenic aerosols has been ignoredExpand
General circulation model assessment of the sensitivity of direct climate forcing by anthropogenic sulfate aerosols to aerosol size and chemistry
Climate response to atmospheric changes brought about by human activity may depend strongly on the geographical and temporal pattern of radiative forcing [Taylor and Penner, 1994]. In the case ofExpand
Global average climate forcing and temperature response since 1750
Estimates are made for the period since 1750 of the major radiative forcing factors thought to be important in climate change. Analysis of these emphasizes the role of biospheric CO2 release andExpand
Marginal direct climate forcing by atmospheric aerosols
Abstract Previous research on the direct effect of atmospheric aerosols on climate has estimated the average radiative forcing per unit sulfate mass, and has used this average to calculate theExpand
Sensitivity of scattering and absorbing aerosol direct radiative forcing to physical climate factors
[1] The direct radiative forcing of the climate system includes effects due to scattering and absorbing aerosols. This study explores how important physical climate characteristics contribute to theExpand
Chapter 3 Aerosol-Climate Interactions
Publisher Summary This chapter discusses the aerosol–climate interactions and is devoted to the direct radiative effects of aerosols. Aerosol layers are composed of submicrometer-sized particles thatExpand
Atmospheric aerosol research in the U. S.: 1991-1994 (95RG00597)
A common theme underlying many aspects of recent atmospheric aerosol research is the role of particulate matter in climate and climate change. Aerosols influence climate directly, by scattering andExpand


Perturbation of the northern hemisphere radiative balance by backscattering from anthropogenic sulfate aerosols
Anthropogenic sulfate (SO 4 = ) aerosol particles play two potential roles in the radiative climate of the earth. In cloud-free air, SO 4 = particles scatter sunlight, some of which is lost to space,Expand
The Effect of Tropospheric Aerosols on the Earth's Radiation Budget: A Parameterization for Climate Models
Abstract Guided by the results of doubling-adding solutions to the equation of radiative transfer, we develop a simple technique for incorporating in climate models the effect of the backgroundExpand
Toward estimation of climatic effects due to arctic aerosols
Abstract During the last decade, the estimation of the climatic implications of principal anthropogenic aerosols (soot and sulphates) has been investigated by observation and modeling efforts atExpand
Sun and dust versus greenhouse gases: an assessment of their relative roles in global climate change
Many mechanisms, including variations in solar radiation and atmospheric aerosol concentrations, compete with anthropogenic greenhouse gases as causes of global climate change. Comparisons ofExpand
Sensitivity of the Earth's radiation budget to changes in low clouds
VARIOUS mechanisms have been suggested whereby clouds might take part in or initiate climate change, including changes in cloud amounts, liquid-water paths and droplet sizes1–11. Previous studies ofExpand
A global three-dimensional model of the tropospheric sulfur cycle
The tropospheric part of the atmospheric sulfur cycle has been simulated in a global three-dimensional model. The model treats the emission, transport, chemistry, and removal processes for threeExpand
An ice-core record of atmospheric response to anthropogenic sulphate and nitrate
RECORDS of sulphate and nitrate concentrations in ice cores show that these concentrations have increased recently because of the long-range transport of pollution from middle latitudes1–5. But theseExpand

Data obtained from measurements of the stratospheric aerosol at Laramie, Wyoming (41�N), indicate that the background or nonvolcanic stratospheric sulfuric acid aerosol mass at northern mid-latitudesExpand
Aerosols, clouds and radiation
Abstract Most of the so-called ‘CO 2 effect’ is, in fact, an ‘H 2 O effect’ brought into play by the climate modeler's assumption that planetary average temperature dictates water-vapor concentrationExpand
Oceanic phytoplankton, atmospheric sulphur, cloud albedo and climate
The major source of cloud-condensation nuclei (CCN) over the oceans appears to be dimethylsulphide, which is produced by planktonic algae in sea water and oxidizes in the atmosphere to form aExpand
