Due to the diversity of products the ECVT collaboration will be organised not only at ‘plenary’ level but also in
subgroups per domain:4

EarthCARE (Validation) in context
This broader context is partially ensured as:•Several EarthCARE PIs have been, are, and will be involved in multiple missions.

Another element could be to collaborate and develop/document common approaches for aerosol profile validation,
cloud-property profile validation, etc.
•Does not limit diversity in intercomparison methods, but supports interpretation of differences in findings•Advances and structures elaborations and interactions (e.g. “possible methods to intercompare
instruments with different vertical sampling and resolution”, or “how to apply the combination of airborne
in-situ with remote sensing (air, ground) for intercomparison with satellite products”, etc.) that would
otherwise take place sometimes as late as the mission operations phase.

•Broadens context, which can be further justification for any funding requests•

If sufficient community momentum is mobilised, then formalisation as CEOS WGCV common practice canbe pursued (see the example of the CEOS biomass validation common practice on the “seed document”
page on the ECVT portal)
