12 scenarios of monthly potential groundwater recharge in southern Quebec Database – 1951-2100 period
- Description:
- This database contains 12 scenarios of potential groundwater recharge (GWR) with a 500 m x 500 m resolution and a monthly time step over southern Quebec for the 1951-2100 period. These data were simulated using the HydroBudget model (Dubois et al., 2021a, b, c) and are presented in Dubois et al. (2022). A selection of 12 climate scenarios from the Coupled Model Intercomparison Project— Phase 5 (CMIP5) ensemble (RCP4.5 and RCP8.5, various global climate models), provided by Ouranos, were used as input. The simulations were performed at UQAM by the team of Pr Marie Larocque’s research Chair on Water and land conservation (Chaire Eau et conservation du territoire), as part of a project funded by the Quebec Ministry of Environment and Climate Change (Ministère de l’Environnement et de la Lutte contre les changements climatiques - MELCC). The study area is located in the Province of Quebec (humid and cold climate; Canada), between the St. Lawrence River and the Canada–USA border and between the Quebec–Ontario border and Quebec City (35 800 km2). The study area is divided into 140 656 cells of 500 m x 500 m. The simulation results are sorted in netCDF files by climate change scenario that contain 1) the 30-year average monthly values and 2) the monthly values for the 1951-2100 period of simulated vertical inflow (VI; sum of observed rainfall and simulated snowmelt – mm/month), average temperature (°C), simulated runoff (runoff + excess runoff – mm/month), simulated actual evapotranspiration (mm/month), and simulated potential GWR (mm/month) for each grid cell. Monthly averages are computed for the periods of 1951-1980, 1981-2010, 2011-2040, 2041-2070, and 2071-2100.
