The Chronometric Tethersonde, Description and Operation

Abstract

An instrument for the detailed study of temperature-height profiles within the lower 500 m of the atmosphere is described. The instrument is carried aloft by tethered balloon and, unlike most other tethered sounding instruments, transmits a continual sequence of measurements regardless of ascent rate. Chronometric principles are employed for data telemetry, permitting the use of simple and economical ground receiving equipment. The sonde has been used quite successfully during the past few years for land and ship-based soundings at various micrometeorological field research sites in Canada.
