When combined with basic optical spectrometers such as prisms or diffraction gratings and automated, ground-based observation platforms, what we have is a cheap and powerful means for the measurement of such trace gas species as ozone and nitrogen dioxide.\r\n\r\nThis instrument is owned and operated by the University of East Anglia","keywords":"doas, uea, ozone, no2","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/3324/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/3325/?format=json"],"instrumentType":"spectrometer","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/56177/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/22526/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/22527/?format=json"]}
