9.00-9.10 Session introduction (O. Andersen)
In Situ Cal/Val process/tools.
9.10-9:25 M. Roca, M. Fornari, A. Garcia, M. Reche, P. N. García, and R. Cullen, (isardSAT, ESA, Pildo Labs) CRYOSAT-2 calibration of data, range and interferometric phase, using an ESA transponder 9.25-9:40 S. Mertikas: Crete transponder permanent calibration site at the crossover point of S3A/S3B and Jason (and Jason-CS)
Discussion: In situ Cal/Val process/tools: - Identify (new) in situ sources/validation methods and how to exploit them
- What do/should we need?
- What about sea-ice regions?
- Establish a potential infrastructure deployment during the post launch phase
Building the error budget table
10.20-10:35 C. Martin-Puig, C. Ray (Starlab): SAR altimetry Ocean Validation
Discussion: Error budget table for LRM and SAR: - How do we quantify errors and uncertainties in the various modes
- How to build it?
- Offset LRM/SAR data. How to identify and model
- Retracking improvement of LRM and SAR.
Data calibration (and quality of corrections)
11.10-11:25 S. Labroue, A. Ollivier, P. Féménias, N. Picot, Y. Faugère, M. Ablain: Quality assessment metrics for Sentinel-3 topography mission over ocean: examples from different altimetric systems
11.25-11:40 R. Scharroo, M. Naeije, E. Schrama, O. Andersen, J. Lillibridge, W. Smith, E. Leuliette, Experiences with the use of RADS for Cal/Val and data distribution.
Discussion: Data calibration (ensuring quality of corrections) - What's available (e.g. CCI round-robin tool)?
- How do we ensure quality of corrections to be applied.
Other points of discussion. - Priority of target surfaces:
- Ocean, Sea Ice, Coastal, Hydrology
- Additional effort needed to ensure this (retracking etc?)
- How to ensure long term stability?
- Any other missing elements.

| 09:00 | Breakout 2: Optical Mission: (OLCI) (Output: 2-4 pages report)
09:00 Introduction to the session and general cal/val requirements for ocean colour; information on the INSITU-OCR initiative from the CEOS ocean colour virtual constellation (D. Antoine)
Onboard calibration. This part is in principle valid for both the O (Ocean) and L (Land) of OLCI.
09:30-09:45 Presentation by Delwart / Bourg (15 min): onboard devices, techniques, requirements… 09:45-10:00 Presentation by P. Henry (15 min): vicarious radiometric calibration (Rayleigh, glint, deserts etc…)
Discussion points - dark currents, gains, spectral model, time degradation model, straylight, smile, camera interfaces, etc…
‘System vicarious calibration’ for ocean colour applications
10:30-10:40 Presentation by Vicarious calibration of MERIS ocean colour radiometry, C. Mazeran, C. Lerebourg (ACRI-ST), J-P. Huot (ESA), D. Antoine (LOV) (10 min)
Discussion points - What have been done for MERIS and other OC sensors that is transferable to OLCI?
- What do we need for vicarious calibration of OLCI? (spectral range 400-865 nm):
- Field sites, requirements in terms of spectral range, accuracy/uncertainty, aerosol measurements etc…)
Validation activities
11:30 – 11:45 Presentation by G. Tilstone including AMT and other activities (15 min)
Discussion points: - Protocols for field measurements and data processing, etc.
- Who will fund fieldwork related to validation activities?
- Role of EEA?
Other topics (data bases, tools, reprocessing etc…)
12:30-12:45 Presentation by O. Hembise (TBC) “Existing tools developed in the MERIS era, to be reused for OLCI/S3”
Discussion points - are these tools appropriate for OLCI?
- do we need other tools?
- what are the reprocessing requirements?
- quality control of inputs to data bases, etc.?

| 09:00 | Breakout 3: Optical Mission: (SLSTR) (Output: 2-4 pages report)
09:00 -09:20 Overview of session (G. Corlett)
Issues for Discussion - What are the priorities for SLSTR Cal/Val?
- What infrastructure is available for Cal/Val?
- What activities are planned for Cal/Val?
- Cal/Val community tools for SLSTR
- What are the missing elements?
- Identify issues that need more validation effort, and how to tackle these.
- Identify new in situ sources/validation methods and how to fully exploit them.
- What can be done for synergy with OLCI
- Land/Ice validation?
- Atmosphere/synergy
- Identify a schedule for potential infrastructure deployment during the post launch phase. Ships and cruises in particular are often decided a long time ahead and ground/marine infrastructure takes time to develop. Having a "strawman" plan of these developments by the end of the workshop would be highly useful.
