Abstract: A new cryogenic hygrometer designed for airborne research has been developed. It is based on the well-known chilled-mirror technique, but instead of the usual Peltier elements, liquid nitrogen is used for mirror cooling. ...

Abstract: A new aircraft device for measuring temperature in clouds is described. Its sensor is a resistance thermometer made of platinum-coated tungsten wire 5 mm long and 2.5 ?m in diameter. The sensor is located on a rotatable ...

Abstract: A new version of an ultrafast aircraft resistance thermometer (UFT-F) with a time constant of the order 10?4 s,for use in both cloudy and cloudless air, is described. It evolved from an earlier version (UFT-S). Its sensing ...
