This archive contains the KK09 scenario of Anthropogenic Land Cover Change (ALCC) covering Europe and neighboring countries and the period 1000 BC to AD 1850. The data and underlying methodology are described in Kaplan et al. (Quaternary Science Reviews, 2009).The data are stored in a NetCDF (version 4) file and have the following attributes:- Spatial extent: 25°W-88°E, 14°N-77°N- Spatial reference system (SRS): Unprojected (geographic, WGS84)- Spatial resolution: 5 arc-minutes (1356 rows by 756 columns)- Temporal extent: 2950 BP (calendar years before AD 1950, approximately 1000 BC) to AD 1850- Temporal resolution: Ten years (decadal resolution; 286 time steps)- Variables: land_use: Total fraction of each 5' grid cell under any land useThree scenarios are presented as in Kaplan et al. (2009): the "low" and "high" scenarios capture a range of uncertainty in past population size and use the standard methodology for translating population into land use, and the "technology" scenario, where the population-land use relationship changes with time.
