It provides a voltage output signal that is proportional to either the incoming sky, or surface emitted IR, depending on instrument mode of operation. The CG4 features a specially designed ellipse shaped solar blind silicon dome, that offers a full 180o field of view, and with good cosine response.","keywords":"","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/2364/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/2365/?format=json"],"instrumentType":"instrument","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/14901/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/14900/?format=json"]}
