It is mounted on a Kipp & Zonen Solys 2 solar tracker to ensure constant pointing in the direction of the sun. It operates in conjunction with pyranometers measuring the total and diffuse solar radiation incident upon a horizontal surface. It is mounted approximately 8 m above ground on the roof of a cabin at the Chilbolton Observatory site.","keywords":"radiometer, direct, visible, irradiance","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/7369/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/7370/?format=json"],"instrumentType":"radiometer","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/50806/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/39792/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/39791/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/140985/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/51038/?format=json"]}
