Two Distromet Joss Waldvogel Impact Disdrometer RD-69 are installed at Chilbolton and Sparsholt and work by converting the vertical momentum of a falling drop into signals whose amplitude depends on the diameter of the impacting drop. A conical styrofoam body is used to transmit the mechanical impulse of an impacting drop to a set of two moving coil systems in magnetic fields.","keywords":"sonic anemometer","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/2391/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/2392/?format=json"],"instrumentType":"instrument","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/15001/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/15000/?format=json"]}
