Analysis of AMIP-20thCv2

A set of integrations of the 2008 experimental version of  the NCEP Global Forecast System spectral model was made using as boundary forcing observed sea surface temperatures and sea ice concentration (HadISST interpolated to our T62, approximately 2x2 degree, grid). Observed time-varying CO2, volcanic aerosols, and solar radiative forcing were also prescribed. The integrations used 28 hybrid sigma-pressure levels. 56 ensemble members were integrated in this "AMIP" style.
