The actinic flux is measured between 280 - 650 nm (<1 nm resolution) using a spectral radiometer (Ocean Optics QE5000) attached to a quartz receiver optic (Metcon). Photolysis rates are derived from the product of absorption cross-section of the precursor molecule, the quantum yield of the photo-product and the actinic flux density (cm-2s-1nm-1).","keywords":"Spectral Radiometer","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/10808/?format=json"],"instrumentType":"other_instrument_type","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/143125/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143123/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143124/?format=json"]}
