25 October 2006 High-precision CO2 sensor for meteorological balloons
Author Affiliations +
A compact, diode laser-based sensor has been developed for meteorological balloons to measure atmospheric carbon dioxide profiles. The sensor achieves a precision of better than 1 ppmv using a novel pressure/temperature compensating reference cell. This device weighs less than 1 kg and uses less than 4 Watts of battery electrical power. Turnkey operation is achieved by a digital signal processor. A full description of the sensor and a discussion of its performance are provided.
