Abstract

Summary form only given. Monitoring the greenhouse effect pointed out from the enviromentology, requires the continuous measurement of atmospheric temperature. However, it is difficult to-measure averaged, not be local, temperature over a large area, since this required the installation of several sensors in each part of the observation area. This paper describes a method-for measuring the average atmospheric temperature between two points by precisely measuring optical path length difference.
