GFDL experiment name: CM3Z_D1_1860-2005_Natural_N5 GFDL parent experiment name: CM3Z_Control-1860_D1 CMIP5 experiment ID: historicalNat Initial conditions from this experiment (CMIP5 expt. 7.1-E(b) Tier 2) were taken from 01Jan0201 of the 1860 control model experiment CM3Z_Control-1860_D1. Uses time-varying forcings from 1/1/1860 through 2005, but only includes: 1) stratospheric volcanos 2) solar forcing 3) dynamic vegetation (1860 land use) This model includes direct and indirect aerosol effects.
