GLOBTEMPERATURE

an ESA DUE initiative

 

International LST and Emissivity Group

The International Land Surface Temperature and Emissivity Working Group (ILSTE-WG) aims to provide advice and recommendations to the wider scientific and user communities on the best practices for retrieval, validation and exploitation of Land Surface Temperature (LST), Ice Surface Temperature (IST), Lake Surface Water Temperature (LSWT), and Land Surface Emissivity (LSE).

Period of report: November 2016

The main activities in this reporting period can be summarised as follows:

  • White Paper on Satellite LST (DEL-28) being finalised
  • Intercomparison V2.2 progress:
    • Analysis and interpretation of the new matched satellite - satellite GT data files (GTATS, MOD11, MYD11, MOGSV and MYGSV vs SEVIRI, GOES) over different regions (West Africa, Southern Great Plains, Iberian Peninsula, Namibia) underpinned by high-quality in situ observations.
    • Analysis and interpretation of the satellite vs. satellites matchups over 3-years at continental / regional scales including polar matchups between LEOs
    • Generation and analysis of IR vs. MW matchups over Africa and Australia
  • Infrastructure being developed to process SLSTR L1 data on S3MPC CTCP into GlobTemperature products (L2P and L3U)
