Record number: 3, Textual support number: 1 CONT
The tetroon is a tetrahedral balloon used for horizontal sounding. It was developed to withstand the extremely low pressures of high-altitude flight; the straight seals joining its four triangular faces are stronger than the curved seals of the more traditionally shaped balloons. Tetroons have been used extensively in tracing low-level atmospheric currents by following their movement with radar; they have thus increased the meteorologist's understanding of atmospheric turbulence, low-level vertical motions, and air pollution dispersion. 3, record 3, English, - tetroon

L'Aéroclipper est un nouvel instrument de mesure conçu pour faire des mesures quasi-lagrangiennes des paramètres de l'interface océan-atmosphère. Un Aéroclipper est constitué d'un ballon tétraédrique fermé de 6 à 7 mètres d'arête, gonflé à l'hélium et stabilisé verticalement à une hauteur de 60 m par un «guiderope». La forme tétraédrique du ballon permet d'avoir un plus fort coefficient de traînée (meilleure prise au vent et donc trajectoire plus «lagrangienne») comparé à un ballon sphérique d'égal volume. De plus, ces ballons sont beaucoup plus faciles et peu coûteux à réaliser avec un matériaux permettant de minimiser les fuites d'hélium. 3, record 3, French, - ballon%20t%C3%A9tra%C3%A9drique
