Spatial scales of climate response to inhomogeneous radiative forcing

Radiative forcing and climate response

We examine the sensitivity of a climate model to a wide range of radiative forcings, including changes ofsolar irradiance, atmospheric CO2, 03, CFCs, clouds, aerosols, urface •bedo, and a "ghost" forcing introduced at arbitrary heights, latitudes, longitudes, easons, and times of day. We show that, in general, the climate response, specifically the global mean temperature change, issensitive to...

2 Radiative Forcing of Climate

Climate response of direct radiative forcing of anthropogenic black carbon

[1] The equilibrium climate effect of direct radiative forcing of anthropogenic black carbon (BC) is examined by 100-year simulations in the Goddard Institute for Space Studies General Circulation Model II-prime coupled to a mixed-layer ocean model. Anthropogenic BC is predicted to raise globally and annually averaged equilibrium surface air temperature by 0.20 K if BC is assumed to be external...
