RAMI workshop on Radiative Transfer Modelling support to EO metrology and Cal/Val activities

The JRC launched the RAdiation transfer Model Intercomparison (RAMI) initiative more than 20 years ago.
RAMI offers a long-term framework to benchmark models designed to simulate radiative transfer at or near the Earth's terrestrial surface as well as at the top-of-atmosphere. This initiative has been instrumental in supporting rigorous radiative transfer model (RTM) evaluation to support Earth Observation Cal/Val activities. With new-generation radiometers on board the Sentinel platforms delivering data with unprecedented radiometric accuracy (often close to 2%), current retrieval methods and validation protocols should be carefully reviewed in order to make sure that they fully benefit from this improved accuracy of the delivered L1b or L1c data.

The primary purpose of this workshop is to discuss how RAMI can support Copernicus Cal/Val activities related to radiative transfer modelling in the context of applying rigorous metrology concepts to validation activities. The following topics will be addressed and discussed during the workshop:

  • RAMI: lessons learned from the JRC and participants;
  • Priorities and goals for new RAMI phases;
  • Links with other EO Cal/Val activities relying on radiative transfer modelling;
  • Impact of SI-traceable satellites on radiative transfer modelling;
  • Toward a RAMI certification for radiative transfer models?
  • Future of RTM developments and applications.

The workshop is intended to the following communities:

  • Radiative Transfer Model developers and users;
  • Scientists involved in EO Cal/Val activities with a focus on Copernicus;
  • Participants to international Cal/Val activities (ACIX, FRM4);
  • Space agencies.

The workshop will be organised around oral presentations selected by the scientific committee.
The event is planned to facilitate the interchange of ideas between (physically present) participants.
