The Scientific Expertise Centre (SEC) “Surface Temperature and Emissivity” brings together teams from Onera, Icube, LSCE, Cesbio and INRA who are all working on improving surface temperature and emissivity estimation and mapping. Users are scientists and institutions.

The updating frequency of the products from the Surface temperature and emissivity SEC will be defined with future users. With a resolution of 50 to 90 m, those products are intended to provide local, regional and national coverage.

The data used come from high-resolution optical imagery such as Sentinel-3, Landsat-5/8, Aster, Spot-6/7, Modis.


  • 2019: Evaluation of the performance of different methods for surface temperature estimation, taking into account the impact of 3D geometry
  • 2020: Coupling of Split-Window/Temperature Emissivity Separation methods
  • 2021: Temperature un-mixing and multi-scale data fusion
