External parameter	Use	Description
Accessibility - grid	Ecosystem services	Accessibility expressed as travel time.
Agricultural land use suitability - grid	Land-use allocation	Suitability of land in a grid cell for agriculture and forestry, as a function of accessibility, population density, slope and potential crop yields.
Biome and eco-region - grid	Terrestrial biodiversity	Biomes are groups of plants and animals, often referred as ecosystems. Their spatial distribution on Earth is defined by climatic and geographical conditions defined as contiguous areas with similar climatic conditions. Biomes are often referred to by climatic conditions (such as, tropical, temperate, boreal) and physiological characteristic (such as, grassland, deciduous trees, coniferous trees).
CLUmondo specific input - grid		CLUMondo specific input.
Coastal storm surges	Flood risks	Estimates on storm surge/tide water levels for a large number of coast segments.
Conversion assumptions	Energy supply and demand	Conversion assumptions.
Daily climate dataset - grid	Flood risks	Bias corrected daily precipitation, temperature and potential evaporation input. This data set is according to the monthly Precipitation and Temperature.
Digital water network - grid	Aquatic biodiversity, Water	Digital water network DDM30 describing drainage directions of surface water, with each cell only draining into one neighbouring cell, organising cells to river basins.
Distance to water - grid	Ecosystem services	Distance to water.
Ecosystem services effect values	Ecosystem services	Database on relationships between environmental factors and ecosystem services.
Emission factors	Emissions	Exogenous emission factors per sector, activity and gas, mostly based on the EDGAR database.
Empirical MSA effect values	Aquatic biodiversity	Database of empirical relationships between environmental pressures and reduction in mean species abundance for aquatic ecosystems.
Exogenously set market shares	Energy demand	Market shares of traditional biomass and secondary heat, for all demand sectors except the residential sector, exogenous scenario parameter.
FAO deforestation rates	Forest management	Historical deforestation rates according to FAO.
Fish landing - grid	Ecosystem services	Fish landings according to statistics from "Sea around us".
Flood statistics - grid	Flood risks	Annual statistics of water depth and the flooded fraction per grid cell.
GCM pattern (temperature, precipitation) - grid	Atmospheric composition and climate	Climate change patterns of General Circulation models used to downscale changes in global mean temperature to changes in temperature and precipitation at grid level; default pattern from HadCM3 of the Hadley Centre.
GLWD (global lakes and wetlands database) - grid	Aquatic biodiversity	Global map of lakes and wetlands.
High resolution land cover (GLC2000) - grid	Terrestrial biodiversity	The database contains two levels of land cover information—detailed, regionally optimized land cover legends for each continent and a less thematically detailed global legend that harmonizes regional legends into one consistent product. The land cover maps are all based on daily data from the VEGETATION sensor on-board SPOT 4.

Initial technology cost	Energy conversion	The costs of energy conversion technologies at the start of the simulation..
Initial temperature, precipitation - grid		Global high resolution climate data from WorldClim.
Investment and Capital Stock	Climate policy	Database on investment and capital stock on country level. Used to determine initial capital stocks and savings rates.
