CARD4L Achievements and Outlook Strong and increasing acceptance of the Concept Data providers are moving toward production of ARD Future Data Architectures have indicated that ARD is a key ingredient Interoperability studies point to the need for ARD as a start point for scientific interoperability Worldcover (March 2017, Frascati) presented several methods to produce analysis ready radar and surface reflectance data Catapult (UK) have independently initiated a series of workshops on Analysis – Ready Sentinel 2 Some appetite to extend the work to include Ocean and Atmosphere ARD (CARD4O; CARD4A)

CARD4L Achievements and Outlook Achievements and next steps: ✔✔ Framework developed

CARD4L Assessment Framework Background The CARD4L Framework

CARD4L Achievements and Outlook Achievements and next steps: ✔✔ Framework developed Product Family Specifications (PFS) – working Drafts of: Surface Reflectance Radar Backscatter Land Surface Temperature / Surface Brightness Temperature Next steps: Use selected datasets to implement the ‘alignment assessment’ components and road-test the PFSs: ALOS PALSAR global mosaics Landsat Collection-2 Sentinel-2 surface reflectance test datasets Two new members to LSI-VC – Daniel Wicks (UKSA), and Andreia Siqueira (GA) This work is moving too fast for some, too slowly for others – so probably about right – but it will accellerate.

Broader CEOS ARD Strategy To be worked during LSI-VC Several questions to consider: Why? What is the problem to be addressed or the benefit to CEOS of a broader ARD strategy? The main arguments seem to be that Future Data Architectures need interoperable ARD. It would also grow the community. How? Would it be done? The core ideas don’t change. The high level definition can be generalised, and we would need to have CARD4O and CARD4A New Product Family Specifications would be needed Who? What are the roles? Who within CEOS would do ‘it’. Some parts of a general scheme (e.g., the definition, the overall framework) should be centrally managed, other parts (Product Family Specifications) progressed within the domains SIT would need to play an oversight role; A new sub-team of FDA would need to be formed to maintain the framework; The VC’s and WG’s would take ownership of Product Family Specifications, Alignment Assessments etc.

How can the LSI-VC and thematic activities work together encourage data providers..? Motivations: Data Providers may need to be: Convinced of the value / benefit of providing CARD4L Supported to move to the CARD4L framework Recognized / Acknowledged for their achievements LSI-VC / CEOS role What can, and should, LSI-VC and the thematic activities do?
