First 2 Leading Patterns of Global SST Variabilty with Observed Radiative Forcing
Description: Observed radiative forcing and ozone with sea surface temperature set to the combined first 2 leading patterns (EOF1+EOF1) of SST variability. Experiment ID: eof1+eof2_sst Years: 1979-2012

ECHAM5 uses a built-in, time independent aerosol model which is based on atmosphere layers, and land and water surface types, described here:

CAM4 uses time-varying aerosol content, and volcano aerosols from 1979-2005. After 2005, RCP6 aerosols (with no volcanoes) are used.
