Lake Snow depth observations derived from Ground Penetrating Radar for four lakes near Yellowknife, Northwest Territories
Borealis
Pouw, Alicia F.; Kheyrollah Pour, Homa — 2023-06-15 This dataset contains snow depth data for Finger Lake, Long Lake, Vee Lake and Landing Lake, just north of Yellowknife, NT. Data includes derived snow depths from Ground-Penetrating Radar Two-Way Travel Times collected using a 1000 MHz sensor paired with the IceMap GPR system from sensors & software. Data was collected in December, 2021, and March, 2022, with data collected twice on one lake. The data is in .CSV file format for each lake. Snow depths derived using Kovacs et al. (1995) method. Interpolated snow depth maps in GeoTIFF format are also included for each lake. These were created using inverse distance weighting of the GPR-derived snow depths.

Great Bear Lake and Great Slave Lake Surface Temperature Retrieved from MODIS Aqua Data
Borealis
Kheyrollah Pour, Homa; Attiah, Gifty — 2024-08-06 The Great Bear Lake and Great Slave Lake Surface Temperature (GBL_GSL_LST) dataset highlights the spatial distribution of lake surface temperature retrieved from MODIS Aqua Data from 2003 to 2023 for the Great Bear and Great Slave Lake in the Northwest Territories, Canada. The data consists of daily individual tiff files for both lakes. The dataset provides insights into the spatial and temporal changing trends of temperature on large Northern lakes.

North Slave Lake Surface Temperature (LST) retrieved from Landsat archives, 1984 to 2021
Borealis
Attiah, Gifty; Kheyrollah Pour, Homa; Scott, K. Andrea — 2023-02-21 The North Slave Lake surface temperature (LST) dataset provides lake surface temperature data for 535 lakes across the North Slave region, Northwest Territories, Canada. An algorithm is applied to the thermal bands of Landsat to retrieve LST from 1984 to 2021. The data consist of individual NetCDF files for observed days for each lake. The North Slave LST dataset provides communities, scientists, and stakeholders with spatial and temporal changing trends of temperature on lakes.

Great Bear Lake and Great Slave Lake Ice Thickness from CLIMoGrid Model
Federated Research Data Repository / dépôt fédéré de données de recherche
Kheyrollah Pour, Homa; Attiah, Gifty — 2024-10-01 The Great Bear Lake and Great Slave Lake Ice Thickness (GBL_GSL_LIT) dataset highlights the spatial distribution of lake ice thickness simulated using the CLIMoGrid Model from 2003 to 2022 for the Great Bear and Great Slave Lake in the Northwest Territories, Canada. The data consists of monthly individual NetCDF files containing daily ice thickness for both lakes. The dataset provides insights into the spatial and temporal changing trends of ice thickness on large Northern lakes. https://creativecommons.org/licenses/by/4.0/
