Radiosonde

Science / Weather / Radiosonde: An instrument attached to a weather balloon used to measure pressure, temperature, humidity, and winds aloft. Observations are made when the radiosonde is aloft and emits radio signals as it ascends. May be referred to as a RAOB, an acronym for RAdiosonde OBservation.

Sounding

Science / Weather / Sounding: A plot of the atmosphere, using data rom upper air or radiosonde observations. Usually confined to a vertical profile of the temperatures, dew points, and winds above a fixed location. MORE

Dropsonde

Science / Weather / Dropsonde: A radiosonde dropped with a parachute from an aircraft rather than lifted by a balloon to measure the atmosphere below. MORE

Rawinsonde

Science / Weather / Rawinsonde: An upper air observation that evaluates the winds, temperature, relative humidity, and pressure aloft by means of a balloon-attached radiosonde that is tracked by a radar or radio direction-finder. It MORE

Rocketsonde

Science / Weather / Rocketsonde: A type of radiosonde that is shot into the atmosphere by a rocket, allowing it to collect data during its parachute descent from a higher position in the atmosphere than a balloon could reach. MORE
