Emission year(s) 2006 (AeroCom-A2.CTRL), 1850 (AeroCom-A2.PRE), no emissions (AeroCom-A2.ZERO). For X = 2006preY all emissions are for year 2006, except for using 1850 emissions for SO2 and SO4 in the Y = SO4 experiment, and similarly (i.e. 1850 emissions) for fossil fuel BC / OC for Y = ffBC / ffOC, and biomass BC and OC for Y = bbBCOC. | |
Emissions: IPCC AR5 for 1850, AeroCom Phase II for 2006, see references in Kirkevåg et al. (2013) | |
