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: 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
  • Computation of the kernel model coefficients of the angular correction for the entire SEVIRI disk for 2011

Period of report: March 2015

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

  • Internal Progress Meeting #3 on 6 March 2015
  • ILSTE-WG Steering Committee telecon held on 12th March
  • LST presented at the GCOS TOPC meeting on 17th March to promote the case of LST as an ECV, which was well received by the panel
  • GlobTemperature ATSR-2 L3 datafiles have finished processing and have been uploaded to the internal FTP server ready for transfer to the Data Portal
  • Produced first matchup data files for the comparison of satellite-retrieved SEVIRI LST with KIT station LST in the harmonised GlobTemperature format
  • Evaluation of the bias correction of MODIS relative to SEVIRI for the Merged Product
  • Preparation of the manually masked images for the CCRR using our cloud clearing tool

Period of report: February 015

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

  • GlobTemperature AATSR L3 datafiles have now been uploaded to the Data Portal
  • GlobTemperature ATSR-2 L2 datafiles have finished processing and are being uploaded to the internal FTP server ready for transfer to the Data Portal
  • Produced first in-situ LST data files for KIT's Kalahari stations in the harmonised GlobTemperature format.
  • Data provision from GlobTemperature is now in line with the UCS requirements.
  • Remaining deliverables due during phase 1 submitted to ESA
    • All approved deliverables now published on the website
  • Date of PM3 set as the 21st of May – the meeting will be hosted by ESTELLUS in Paris

Period of report: January 2015

  • Opening of registration for UCM#3 and first announcement made
    • Set-up of a dedicated website at: http://ucm3.globtemperature.info to collect registration and abstracts
  • AATSR Level-3 data has been uploaded to the FTP server and is in the process of being added to the Data Portal
  • The L4 LST global Merged GEO Product Prototype at UTC times for period 2011 has been uploaded to the GlobTemperature ftp server
  • The L4 LST global Merged LEO Product Prototype at 4 local times daily for the period 2011 has been uploaded to the GlobTemperature ftp server
  • A L4 LST global Merged GEO+LEO Product Prototype for period 2011 has been produced from the Merged GEO + an “internal” Merged LEO at UTC times has been uploaded to the GlobTemperature ftp server

Period of Report: December 2014

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

  • The data portal is now open and functional – announcement to the users’ community was made on the 12th of December. The first three datasets are now available: AATSR, SEVIRI and SSM/I
  • The Product User Guide (PUG) is now published on the website and available from the data portal as well
  • UCM#3 will be held at University of Reading from 11th June (full day) to 12th June (half day). This will be preceded by both the 4th EarthTemp Network Meeting and the 6th LSA SAF Workshop, and
    followed by the 3rd General Meeting of the ILSTE-WG
  • Joint NASA MEaSUREs – ILSTE-WG 2nd General Meeting was held on Wednesday 17th December between 18:00 and 20:00 in San Francisco in conjunction with AGU 2014
  • Invited presentation of GlobTemperature progress in EarthTemp Session given by D. Ghent at AGU 2014
  • Final developments for both the Prototype Merged LST Product and the Prototype Climate Data Record being made ready for delivery to the Data Portal in January
