The CAM4 radiative feedback Green's function

• Description 

The Green’s function represents the sensitivity of a global averaged response (top-of-atmosphere radiation, surface air temperature, etc) to changes in the sea surface temperature (SST) of individual geographic locations, which consists of both local and nonlocal effects of SST changes. The full sensitivity matrices are constructed from a series of prescribed-SST simulations with the Community Atmosphere Model version 4 (CAM4) , each with a single patch of SST warm anomalies on the top of climatological SSTs. Convolving the Green's functions with a given global SST anomaly pattern predicts the global response to that particular warming pattern.
