From these measurements the integrated water vapour and total liquid water at zenith are derived, together with the vertical profile of water vapour density.","keywords":"","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/2395/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/2396/?format=json"],"instrumentType":"asoz","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/15019/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/15018/?format=json"]}
