Dataset

  • generally: data from one provider, one (satellite) instrument or one model.
  • Need to further clarify granularity for model data. For example: "MACC" or "MACC forecast" and "MACC reanalysis"

Parameter

  • relatively clear (= "variable name", "field name" or "layer name")
  • issue: same parameter can come in different units (e.g. surface ozone in ug/m3 or ppb) - "units" is a separate facet, so it is possible to make selection if two variants of the same data are on offer
  • rerlation to CF standard_name: parameter name should be extract from standard_name describing the physical quantitiy without its representation

Platform

  • predefined values: satellite, surface observation, vertical profile, model, emission (/!\ CHANGED) -- check common data model; climate community

Instrument

  • new tag for method should be added
  • instrument tag may not be available in some services and will get lost in aggregation
  • present agreement on "coarse resolution catalogue" would not allow mapping of intrument and method as it will not go down to the level of individual stations
