data types - satellite, aircraft, land obs, computation, climate

[gap736uk]

I've done a pass through MOLES obs records to try and do some route classification in terms of the types of data we have.. This is predicated mainly on the process type... logic as follows:

for obs records in preview, published or citable state...

if nonGeographicFlag -> lab data else -if acquisition - check for platform types and list else - if composite process look for acquistion and check for platform types else - mark as computaiton

this gives us:

computation
lab
land_station
mooring
moving_platform
None
satellite
ship
stationary_platform
station_group
UNDEFINED```

Out of 7052  returns 545 had 'None' defined... the list of paths shows there is some tidy-up work needed in parts of the archive.

Main question is how to split the 'computation' group as NWP, climate modelling etc groups are important...

and whether platform types for obs data should be mapped to smaller groupings... e.g remote sensing, surface obs etc.

Regarding the Computation one draw on computation classifcation work that Harriet undertook for CEDA over the summer.

Question - how to get these top level tags into stac to provide the top level search? @rsmith013

something like: facet name: 'data from' list: controlled vocab to be determined... something like:

• laboratories
• land surface stations
• remote sensing instruments
• sea surface stations
• satellites
• ships
• aircraft
• NWP models
• Climate models
• Reanalysis model runs
• Other computation types
• UNDEFINED

from GPs initial sweep from MOLES need to figure out if we can map: stationary platform moving platform

@rsmith013 - I can divide things up like this based on MOLES info... and relate that to a path in the archive... (and there are other tags that we could use too such as the GEMET Theme, INSPIRE topic category) ..but how would these be used.

Feedback from Wendy:

mobile instruments (other than on aircraft/ship) - land surface stations doesnt quite cut it - how about surface measurements instead of stations
