Associate Research Professor Alexandra (Sasha) Tyukavina, Associate Professor Sergii Skakun and Emeritus Research Professor & Adjunct Professor Eric Vermote (NASA) participated in the European Space Agency (ESA) Workshop On Land Product Validation and Evolution (LPVE23) on June 12 to14 in Frascati, Italy.

The LPVE23 Workshop was organized by ESA in collaboration with the Land Product Validation subgroup (LPV) of the Committee on Earth Observation Satellites (CEOS) Working Group on Calibration Validation (WGCV).

The objectives of the program were to:

  • review the status and evolution of retrieval methods and Cal/Val approaches for satellite-derived terrestrial essential climate variables (ECVs);
  • revisit existing Cal/Val infrastructure and protocols and their readiness in the light of future satellite land missions;
  • promote synergies and foster cooperation across existing Cal/Val Networks;
  • report on recent field campaigns and promote adoption of metrological practices in Cal/Val, following the principles of Fiducial Reference Measurements (FRM); 
  • report on latest progress on radiative transfer models and products inter-comparison exercises and discuss data harmonization across sensors;
  • formulate recommendations for future land products and gather Cal/Val needs in terms of ground-based infrastructure and data availability, accessibility, timeliness. 

GEOG researchers contributed to the following presentations and posters:

  • “Approaches to global sampling for land cover map validation” (A. Tyukavina)
  • “Ground based Validation over land of the passive optical remote sensing data” (E. Vermote)
  • “CMIX-II: Second edition of the Cloud Mask Inter-comparison eXercise” (S. Skakun)
  • “The impact of mapping accuracy on crop area estimation: the case of winter wheat in Ukraine” (S. Skakun)
  • “Artillery crater mapping in VHR satellite imagery: methodology and validation aspects” (S. Skakun)
