Climate scenarios RCP 1981-2100 – mGROWA – annual – after 30-year periods – groundwater supply, total outflow, direct outflow, actual evapotranspiration and number of days with snow cover

The collection contains the results of the mGROWA water balance model on groundwater supply (Qrn), total effluent (Qn), direct effluent (Qd), actual evapotranspiration (Eta) in mm and the number of days with snow cover (Ndsp) for the period 1981-2100 for greenhouse gas emission scenarios RCP2.6, RCP4.5 and RCP8.5. The data shall contain 30-year averages (1982-2010, 2011-2040, 2041-2070, 2071-2100) of minimum and maximum values and median values of six (two) models for scenarios RCP4.5 and RCP8.5 (RCP2.6) at a spatial resolution of 100 m x 100 m. The basis shall be the hydrological year. The data are the result of the mGROWA water balance model. Information on the mGROWA model methodology and results is provided in the literature cited below. ARSO assumes no liability for damages arising from the use of data. Files in names contain: - selected climate scenario: RCP2.6, RCP4.5, RCP8.5; - variable name: • Qrn: Groundwater supply • Qn: Total outflow • Qd: Direct outflow • Eta: Actual evapotranspiration • Ndsp: number of days with snow cover; - information on the period; - y symbolizes data on an annual basis (year); min, max and honey mean the minimum, maximum values and median of six models for scenarios RCP4.5 and RCP8.5 and two models for scenario RCP2.6. The data is recorded in ASCII raster format and the coordinate system D48 Slovenija (ESPG 3912) is used. If data is used, the Data Administrator (ARSO) must be informed and the literature listed below must be quoted accordingly.
