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: April 2015

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

  • ILSTE-WG to lead a draft note to the GCOS TOPC detailing the definitions of LST, LSE and cross-cutting benefits to other ECVs for potential recommendation by TOPC of reclassification of LST to an ECV
  • UCM#3 preparations ongoing:
    • Registrations currently number 65
    • UCM#3 abstracts reviewed and acceptance confirmations sent out for oral and poster presentations
    • First draft programme produced
  • Internal tests carried out on new functionalities for the Data Portal:
    • Selection and extraction of data according to geographical criteria
    • Possibility to record areas of interest and to label them for later use
    • Repository to allow users to share their tools
  • Full Terra and Aqua MODIS Level-2 from start of missions to end-2014 have now been reprocessed into GlobTemperature harmonised format
  • Started development and production of match-up files in harmonised GlobTemperature format for satellite-retrieved MODIS LST and SURFRAD station LST
