The International Land Surface Temperature and Emissivity Working Group is associated with projects carried out all around the world. These projects are briefly presented below.

DUE GlobTemperature

The aim of ESA’s GlobTemperature project is to overcome the barriers preventing wider uptake of global-scale satellite LST by the broad research and operational user communities.

The GlobTemperature project has:

  • Developed a merged LST data set from thermal infrared (geostationary & polar orbiter) and passive microwave satellite data to provide best possible coverage, including information on the diurnal cycle and clear-sky bias
  • Developed a prototype LST climate data record from (A)ATSR
  • Performed an open intercomparison of methods to confront the user demand for better cloud clearing over land
  • Demonstrated the benefits of satellite LST through user case studies
  • Provided 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
  • Engaged with the user community, respond to feedback, and bring the user and developer communities together
  • Challenged the next generation of satellite LST products to better meet the requirements of the users.
