The Sea-Ice Thematic Data Products (TDP) are taking into account the improvements made in the frame of the REAPER project and the ENVISAT reprocessing 3.0. The Sea-Ice will propose products containing sea-ice freeboard and sea-ice thickness with a common product definition. An uncertainty value will be computed for each measurement.

 

Data Access

Will be available at the end of the project (end of 2022)

Processing & Algorithms

  • Deblurring algorithm on ERS echoes : Theoretical approach based on the methodology detailed in [Peacock,2004]
  • ENVISAT freeboard calibration using a novel neural-network approach
  • ERS freeboard calibration

Improvements compared to existing products

Preliminary results on the ENVISAT freeboard correction already show good performances on a testing period (March 2012) :
