This dataset contains new detailed surface water maps of Canada showing where and how often surface water has occurred at each location across Canada, and how it has changed from 1984-2023. Freely-available archived imagery from the Landsat series of satellites was used to map water at bi-weekly and annual time periods, and these time-series were used to create dynamic surface water maps at 30m spatial resolution across Canada. **This third party metadata element follows the Spatio Temporal Asset Catalog (STAC) specification.**

The datasets contain land surface evapotranspiration (ET, in mm of H2O) for Canada's landmass at a spatial resolution of 5-km and temporal intervals of a month over a 24-year period of 2000-2023. The ET was produced by the Land Surface Model EALCO (Ecological Assimilation of Land and Climate Observations) developed at Natural Resources Canada. The EALCO model was run at a 30-minute time step. The monthly ET in the datasets is the sum of the 30-minute ET values in a month. Dew and frost formations simulated by EALCO are included in the ET as negative values, so the ET represents the net water flux between land surface and the atmosphere. Details of the datasets and the EALCO ET modelling algorithms can be found in Wang (2007, Simulation of Evapotranspiration and Its Response to Plant Water and CO2 Transfer Dynamics. J. Hydrometeorology, 9, 426-443, doi: 10.1175 **This third party metadata element follows the Spatio Temporal Asset Catalog (STAC) specification.**
