Hydrologic outputs from the 2023 calibrated version of GEM-Hydro over the Great-Lakes and Ottawa River region
| Description: | This dataset contains outputs from a calibrated version of the GEM-Hydro hydrologic model developed at Environment and Climate Change Canada (ECCC), over the Great Lakes and Ottawa river basins, and for the period 2001-2018 included. The outputs consist of all variables (hourly fluxes and state variables) related to the land-surface tile water balance of the surface component of GEM-Hydro, as well as mean daily streamflow time-series (observed and simulated with the routing component of GEM-Hydro), at gauge locations of the region of interest. To produce these outputs, a calibrated version of the GEM-Hydro model was run in open-loop mode (no land-surface or streamflow assimilation performed), but driven with atmospheric forcings coming from ECCC’s version 2.1 of the Canadian Surface Reanalysis (CaSR). More information can be found in the Readme file. The hydrologic variables of this dataset include precipitation, surface runoff, sub-surface runoff (soil lateral flow), soil base drainage, evapo-transpiration, snow water equivalent, soil moisture content for 6 soil layers down to 2m, water stored in the vegetation canopy, and streamflow. These variables can be used for example to run and calibrate any routing model, compute climatologies, various statistics, or trends for different hydrologic variables over the region of interest, assess the variability of these variables as a function of the local geo-morphology, etc. |
