The CMIP5 data includes: 1) historical atmospheric concentrations as well as concentrations for the RCPs (2005-2100) and their extension to 2300 (ECPs). In total, atmospheric concentration of the following gases are provided: CO2, CH4, N2O, all flourinated gases controlled under the Kyoto Protocol (HFCs, PFCs, and SF6), and ozone depleting substances controlled under the Montreal Protocol ( CFCs, HCFCs, Halons, CCl4, CH3Br, CH3Cl). 2) historical emissions data (1850 - 2000) as well as emissions for the RCPs (2000-2100). In total emissions of the following gases are provided: CH4, SO2, NOx, CO, NH3, as well as of BC, OC and VOC. Other additional species such as C2H4O (acetaldehyde), C2H5OH (ethanol), C2H6S (dimethyl sulphide), C3H6O (acetone), etc. are available only for historical biomass burning emissions (see below). 3) historical aerosols data (1850 - 2000) on the following species: sulfate (SO4), ammonium nitrate (NH4NO3), hydrophobic black carbon (CB1), hydrophilic black carbon (CB2), hydrophobic organic carbon (CB1), hydrophilic organic carbon (CB2), secondary organic aerosols (SOA), dust (DST01-04, small to large sizes)) and sea-salt SSLT01-04). In addition, temperature (T) and surface pressure (PS) is provided to enable unit conversion (all aerosol are in kg/kg, dry mass). 4) historical and RCP land-cover projections. == We’ve downloaded a number of binaries from == http://www.pik-potsdam.de/~mmalte/rcps/index.htm#Download RCP45SCP45TO3PD_MIDYEAR_CONCENTRATIONS.DAT RCP_CONTROLRUN_CONCENTRATIONS.DAT RCP45SCP45TO3PD_EMISSIONS.DAT RCP3PD_MIDYEAR_RADFORCING.DAT RCP85_MIDYEAR_RADFORCING.DAT RCP6_MIDYEAR_RADFORCING.DAT RCP6SCP6TO45_MIDYEAR_RADFORCING.DAT RCP45SCP45TO3PD_MIDYEAR_RADFORCING.DAT RCP45_MIDYEAR_CONCENTRATIONS.DAT RCP6_MIDYEAR_CONCENTRATIONS.DAT RCP6_EMISSIONS.DAT RCP6SCP6TO45_MIDYEAR_CONCENTRATIONS.DAT RCP6SCP6TO45_EMISSIONS.DAT RCP85_EMISSIONS.DAT RCP85_MIDYEAR_CONCENTRATIONS.DAT RCP45_EMISSIONS.DAT RCP3PD_MIDYEAR_CONCENTRATIONS.DAT RCP3PD_EMISSIONS.DAT 20THCENTURY_MIDYEAR_RADFORCING.DAT 20THCENTURY_MIDYEAR_CONCENTRATIONS.DAT 20THCENTURY_EMISSIONS.DAT RCP45_MIDYEAR_RADFORCING.DAT == Availability at IPSL == RCPs are available and stored on the common account IGCM/STORAGE/BC/ATM/IPCC_AR5/RCPs/ == Quick links == http://www.pik-potsdam.de/~mmalte/rcps/20c3m.htm http://www.iiasa.ac.at/web-apps/tnt/RcpDb/dsd?Action=htmlpage&page=download ftp://ftp-ipcc.fz-juelich.de/pub/emissions/gridded_netcdf/tarfiles/
