Land Surface Temperature
Overview
This layer shows land surface temperature (LST) for each pixel from the Landsat surface temperature band as retrieved from Google Earth Engine. The layer reports the 95th percentile LST value calculated from a mosaic of cloud masked Landsat images from years 2023-2025 selected from the 90-day window centred on the median hottest date as determined from ERA5 DAILY.
Function
To identify potential areas of high heat risk.

Cautions
Land surface temperature, while widely available, is a poor proxy for the heat hazard experienced by people. If available for the full area of interest at sufficient resolution, consider using a heat hazard metric more directly correlated with human health, such as air temperature or universal thermal climate index. Note also that we display extreme values: the highest (95th percentile) values taken from each location's hottest season.
