Abstract: An air/sea temperature probe is disclosed which can be deployed from a moving ship to detect the temperature profile of the atmosphere and ocean beyond the thermal influence of a ship. The probe includes a temperature transducer which utilizes a bifilar wire that provides a very quick air temperature time constant. The transducer is mounted within a radiation shield having low thermal conductance to minimize thermal and solar radiation contamination and is coupled to a signal processing network. In operation, the probe is deployed from a ship and provides temperature telemetry via an electrical data link coupled between the signal processing network and a receiving transducer located onboard the ship.
