mHM_UFZ gridded simulations for the Great Lakes Runoff Inter-comparison Project for Lake Erie

This dataset provides gridded model simulations in netcdf format over the Lake Erie using the mHM model (Samaniego, et al., 2010, Kumar et al, 2013), done within the Great Lakes Runoff Inter-comparison Project for Lake Erie (GRIP-E).

Model code is available under: https://git.ufz.de/mhm/mhm, revision number: 8271b54

Domain boundaries (WGS84 system): lon_min = -86.0, lon_max = -78.0, lat_min = 40.0, lat_max = 45.0

Model variables are simulated at spatial grid of 0.125deg x 0.125deg, daily time step. 

Simulation period: 01 Jan 2011 - 31 Dec 2014 (with 1year -2010- warm-up)

Meteorological input data, see Mai et al. 2020 (in prep)

Following model variables are provided for two mHM_parameter.nml realizations (*obj1 and *obj2, as defined in Mai et al. 2020 in prep).

===============================================================

These data and model runs have been performed under the Great Lakes Runoff Intercomparison Project for Lake Erie (GRIP-E)  led by Juliane Mai and Bryan Tolson (both University of Waterloo) and funded under the Integrated Modelling Program for Canada (IMPC) within the Global Water Futures program. This work has received funding from the Initiative and Networking Fund of the Helmholtz Association through the project Advanced Earth System Modelling Capacity (ESM) (www.esm-project.net).
