FRM4SOC workshop

5 – 7 December 2022
EUMETSAT, Darmstadt, Germany

Fiducial Reference Measurements (FRM) are a suite of independent, fully characterised, and metrologically traceable ground measurements that follow the guidelines outlined by the Quality Assurance Framework for Earth Observation (QA4EO) of the Committee on Earth Observation Satellites (CEOS). These FRM provide the maximum return on investment for Copernicus satellite missions by delivering, to users, the required confidence in data products as independent validation results and associated uncertainties on both ground-based and satellite measurements over the entire duration of a mission. In 2016 – 2019, European Space Agency funded the first phase of the FRM4SOC (Fiducial Reference Measurements for Satellite Ocean Colour) project to improve ocean colour validation through a series of proof-of-concept tasks. The FRM4SOC Phase 2 - funded by the European Commission - was launched by EUMETSAT in April 2021 to consolidate what was achieved during phase-1 and provide clear guidelines and tools for the ocean colour community to ensure the FRM quality of measurement results.

At this workshop, we present the most important outcomes from the FRM4SOC phase project and seek for agreement in the community through discussions.

City of Darmstadt

Darmstadt is located just 30 km south of Frankfurt am Main in Hesse. The city enjoys a reputation as a ‘City of Science’ thanks to the many public and private scientific research establishments located there, not to mention the Headquarters of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and the European Space Operations Centre (ESA/ESOC).

However, Darmstadt is not only a “city of science”, but also a city of art and culture. It combines research, science, economy, culture, and quality of life in a special way. Home to top researchers, musicians, engineers and artists for centuries, today’s Darmstadt is the product of a unique fusion between artistic traditions and technological advancement.


General overview

The aim of this workshop is to present the project outcomes in a dialog form. The deliverables presented will be updated after the workshop according to the feedback received from the community. Therefore input from all the participants is extremely welcome!
