Abstract:

Six papers have been published in the literature during the past two years, related to the development and performance of the Doppler Lidar Detector System, and its associated wavelength meters. The instrumentation and all of the necessary software is now available at University College London. Three complete Doppler DetectorWavelength meter units have been fabricated. One of these has been delivered to AFGL, awaiting the completion of the Laser system. Another one of these combined units was integrated temporarily with the complete Lidar system of the Bonn University group at Andoya in August 1987, for proof of concept, and to demonstrate that all of the optical and electronic interfaces and software functioned correctly. Due to limited time in the field, and very poor weather, it was not possible to obtain direct data on the lower thermosphere, but the tests did prove that the entire system functioned as designed. Further tests with Bonn University are planned in 1988.
