Lake surface temperature retrieved from Landsat satellite series (1984 to 2021) for the North Slave Region
Lake surface temperature (LST) is an important attribute that highlights regional weather and climate variability and trends. The spatial resolution and thermal sensors on Landsat platforms provide the capability of monitoring the temporal and spatial distribution of lake surface temperature on smal...

Lake surface temperature (LST) is an important attribute that highlights regional weather and climate variability and trends.
