Anthropogenic aerosol radiative forcing in Asia derived from regional models with atmospheric and aerosol data assimilation
Anthropogenic aerosol radiative Asia regional models atmospheric aerosol data assimilation
2010/8/16
An estimate of monthly 3-D aerosol solar heating rates and surface solar fluxes in Asia from 2001 to 2004 is described here. This product stems from an Asian aerosol assimilation project, in which a) ...
Sulfur cycle and sulfate radiative forcing simulated from a coupled global climate-chemistry model
Sulfur cycle sulfate radiative a coupled global climate-chemistry model
2010/8/12
The sulfur cycle and radiative effects of sulfate aerosol on climate are studied with a Global tropospheric Climate-Chemistry Model in which chemistry, radiation and dynamics are fully coupled. Produc...
Total aerosol effect: radiative forcing or radiative flux perturbation?
radiative forcing radiative flux perturbation
2010/8/12
Uncertainties in aerosol radiative forcings, especially those associated with clouds, contribute to a large extent to uncertainties in the total anthropogenic forcing. The interaction of aerosols with...
A simulation of the global distribution and radiative forcing of soil dust aerosols at the Last Glacial Maximum
global distribution radiative forcing soil dust aerosols Last Glacial Maximum
2009/5/15
In this study an integrated simulation of the global distribution and the radiative forcing of soil dust aerosols at the Last Glacial Maximum (LGM) is performed with an aerosol climate model, SPRINTAR...
Modelled radiative forcing of the direct aerosol effect with multi-observation evaluation
Modelled radiative forcing direct aerosol effect multi-observation evaluation
2009/3/13
A high-resolution global aerosol model (Oslo CTM2) driven by meteorological data and allowing a comparison with a variety of aerosol observations is used to simulate radiative forcing (RF) of the dire...
An exploration of ozone changes and their radiative forcing prior to the chlorofluorocarbon era
ozone changes radiative forcing chlorofluorocarbon era
2009/3/12
Using historical observations and model simulations, we investigate ozone trends prior to the mid-1970s onset of halogen-induced ozone depletion. Though measurements are quite limited, an analysis bas...
DMS atmospheric concentrations and sulphate aerosol indirect radiative forcing: a sensitivity study to the DMS source representation and oxidation
DMS atmospheric concentrations sulphate aerosol radiative forcing
2009/3/10
The global sulphur cycle has been simulated using a general circulation model with a focus on the source and oxidation of atmospheric dimethylsulphide (DMS). The sensitivity of atmospheric DMS to the ...
Radiative forcing since preindustrial times due to ozone change in the troposphere and the lower stratosphere
Radiative forcing preindustrial times ozone change troposphere lower stratosphere
2009/1/4
Changes in atmospheric ozone have occurred since the preindustrial era as a result of increasing anthropogenic emissions. Within ACCENT, a European Network of Excellence, ozone changes between 1850 a...
