1. Discussion on intermediate data storage for inter-calibration activities
Prepared by S. Wagner

2. Inter-calibration and use of common references
Context :
Inter-calibration and use of common references across the various GPRCs + partners
Real or virtual generation of intermediate dataset in the processing chains before deriving the final GSICS products
Questions:
Need for sharing information on the intermediate steps / dataset?
Usefulness for reprocessing activities?
Common database/storage for data reference instruments?

3. Why is there a need?
Need for sharing information on the intermediate steps / dataset?
Possibility to check / validate the implementation of a common ATBD across the various GPRCs
Possibility to run common cases to secure the validation of a product
Possibility to trace back differences in products (in particular if more GPRCs generate a same product, but not only…)
Increase interactions between GSICS R&D WG members and partners

4. Why is there a need? Usefulness for reprocessing activities?
To speed-up reprocessing:
No need for uploading archived full images from various instruments
Pre-processing done (SNOs, DCCs extraction, etc.)
To allow stand-alone analysis (away from ground-segments and reprocessing chains)
Increase interactions between GSICS R&D WG members and partners

5. Why is there a need?
Common database/storage for data reference instruments?
Same reference dataset(s) across the various GPRCs (e.g. DCCs where statistical approach over large amount of data is performed)
Speed-up the processing as preprocessing is already done (in particular for MODIS)
Increase interactions between GSICS R&D WG members and partners

6. Why is there a need?
What else do we want / need ?
