Round Table: Scientific and Operational Roadmap for Satellite Altimetry Cal/Val

  • Critically review the current methodology applied at the Permanent Facilities for satellite altimetry calibration and validation using ground-based measurements;
  • Define requirements, establish standards and provide recommendations and best practices for altimerty calibration such that all measurements and results made for monitoring the Earth, the environment, the sea level, etc., are well-characterized and linked to other areas of science and technology through a world’s measurement system established and maintained under the International System of Units and Metrology Standards;
  • Document procedures for Fiducial Reference Measurements in satellite altimetry so that results are traceable to SI-units, reliable in the long term, comparable worldwide, to support an objective and unquestionable monitoring of the Sea Level and Climate Change;
  • Establish procedures and protocols for characterizing the uncertainty budget of all FRM instruments and derived results over the entire end-to-end duration of a satellite mission;
  • Define and document procedures, protocols and best practices to evaluate differences in instrument performances under a range of conditions to maintain satellite altimetry observations, to support the Earth Observation for the future;
  • Summarize all scientific achievements for satellite altimetry Cal/Val and its applications in the context of Fiducial Reference Measurements.

SeRAC: Sentinel-3 Radar Altimeter Calibration Site in Crete

Serac crete eu

 

FRM4ALT is continued in the Sentinel-3 Radar Altimeter Calibration in Crete (SeRAC) activity with Operational Support, now in place. The objective of this SeRAC project is to ensure the routine operations and maintenance of the CDN1 transponder Cal/Val site for Sentinel-3A but also for Sentinel-3B Commissioning and Routine Operational Phase. The transponder Cal/Val operations shall be further supported by the sea-surface Cal/val sites established at the Permanent Facility for Altimetry Calibration in west Crete, Greece.
