For the period 1850 to 2000, it is created from linear time interpolation of the decadal monthly mean historical ACCMIP (Atmospheric Chemistry and Climate Model Intercomparison Project) emissions. The historical ACCMIP dataset described in Lamarque et al. (2010) provides 0.5 degree horizontally gridded decadal monthly mean emissions for the years 1850 to 2000 as a best guess historical emission estimate constructed from a harmonised combination of existing regional and global inventories. For the period 2000 to 2100, this dataset is created from linear time interpolation of the future emission projections related to four different Representative Concentrations Pathways (RCPs), RCP2.6, RCP4.5 RCP6 and RCP8.5, described in the overview paper of van Vuuren et al. (2011). The numbers denote the radiative forcing target levels for the year 2100 of 2.6, 4.5, 6 and 8.5 W/m2, respectively, based on the forcing of greenhouse gases and other forcing agents. For more details, please also refer to RCP database at http://www.iiasa.ac.at/web-apps/tnt/RcpDb. The year 2000 historic ACCMIP emissions acted as a starting point (handshake year) for the development of these RCP emission scenarios. The RCP emission files are given for each decade until 2100, starting in the year 2000, with extra files for the year 2005. The decadal ACCMIP and RCP files are accessible from RCP database (Version 2.0) at http://www.iiasa.ac.at/web-apps/tnt/RcpDb. The database contains an identical copy of the latest version of the decadal files stored at ftp://ftp-ipcc.fz-juelich.de/pub/emissions/gridded_netcdf/decadal, see also ftp://ftp-ipcc.fz-juelich.de/pub/emissions/gridded_netcdf/release_history_gridded_netcdf.txt. In the historical decadal ACCMIP emission files, the anthropogenic and aircraft emissions represent the first year of the decade, while ship emissions represent the 5th year of the decade. The biomass burning emissions represent average conditions of the respective decade (e.g. 1980-1989 mean values are contained in the year 1980 file) except for the 2000 estimate which is calculated from the 1997-2006 average. The RCP scenario emissions are representative for the first year of the decade, except for the year 2005 RCP emissions (which are representative for the year 2005). The historic ACCMIP emissions and the RCP projections provide a seasonality only for the biomass burning emissions. In order to create monthly files for each year, linear time interpolation between the decades was performed for each sector taking into account the respective timestamp of the decadal ACCMIP and RCP emissions. In more detail, the decadal historic anthropogenic emissions and all RCP emissions were assigned to the first year of each decade while historic ship and biomass burning emissions were assigned to the 5th year of each decade. Emissions of the year 2000 are an exact copy of the year 2000 emissions contained in the historic decadal ACCMIP emissions dataset. The emissions of the year 2001, for example, were calculated from linear time interpolation between the decadal year 2000 ACCMIP emissions and the year 2005 RCP emissions. On a yearly global average, the interpolated anthropogenic ACCMIP and RCP8.5 emissions of the years 1980 to 2010 contained in this database are practically identical with the ACCMIP MACCity anthropogenic emissions described in Granier et al. (2011) (available at ECCAD GEIA database (http://eccad.sedoo.fr), see also http://accent.aero.jussieu.fr/MACC_metadata.php), which used a similar linear interpolation procedure. In contrast to this dataset, which has no seasonality for the anthropogenic emissions, the source-specific seasonality developed for the RETRO project (http://retro.enes.org/) was applied to each sector in the ACCMIP MACCity anthropogenic emissions. Both dataset differ by less than 0.1% in respect to their yearly global anthropogenic totals. The sector-wise relative difference in the yearly global totals is less than 0.3% except for ship emissions. Due to a different timestamp assigned to the historic ship emissions during the interpolation procedure, the relative difference reaches 20% in some years. Summary statistics of annual global total emissions per sector are available at ftp://ftp-ipcc.fz-juelich.de/pub/emissions/summary_statistics/. The interpolated anthropogenic ACCMIP and RCP8.5 emissions for the years 1850 and 1960 to 2010 contained in this database are identical with the AEROCOM-II ACCMIP hindcast emission source files available at http://aerocom.met.no/download/emissions/AEROCOM-II-ACCMIP/ (see also Diehl et al. (2012)). The AEROCOM-II ACCMIP source files comprise emissions for the species CO, CH4, NH3, SO2, BC, OC and NOx. AEROCOM-II ACCMIP hindcast emission source files for biomass burning emissions consist of ACCMIP MACCity biomass burning emission data for the period 1960 to 2008 (see below) and interpolated RCP8.5 biomass burning emissions from this dataset for the years 2009 and 2010. One key characteristic of biomass burning emissions is their strong interannual variability, which is not captured in this interpolated biomass burning emission dataset. If an explicit interannual variability of biomass burning emissions is of interest for a study, we recommend using the ACCMIP MACCity biomass burning emission data, available at ftp://ftp-ipcc.fz-juelich.de/pub/emissions/gridded_netcdf/ACCMIP_MACCity. The ACCMIP MACCity biomass burning emission data, which are available for the period 1960 to 2008, are the original data used to construct the decadal monthly mean ACCMIP biomass burning emissions, see also ftp://ftp-ipcc.fz-juelich.de/pub/emissions/gridded_netcdf/ACCMIP_MACCity/README.ACCMIP_MACCity.txt. All anthropogenic sectors are stored in the anthropogenic file, except for ship and aircraft emissions, which are kept in individual files. The two biomass burning sectors are kept in a separate biomass burning file. Please note that the number of sector variables contained in the anthropogenic files depends on the species.
