The aim of the ESA GlobTemperature project is to overcome the barriers preventing wider uptake of global-scale satellite Land Surface Temperatures (LST) by the broad research and operational user communities. The project provides users with a single point of access to multi-mission satellite land, lake and ice surface temperature data sets in a harmonised format, including consistently generated uncertainty budgets, documentation, and quality information obtained through intensive intercomparison and validation. By merging LST data from thermal infrared (geostationary & polar orbiter) and passive microwave satellites, GlobTemperature provides the best possible coverage, including information on the diurnal cycle and clear-sky bias.
