Abstract

Over the past five years the feasibility of spaceborne differential absorption lidar (DIAL) systems for the purposes of trace gas monitoring in the atmosphere has been studied [1,2,3]. The feasibility of such instruments is supported by the results of studies such as ORACLE (Ozone Research with Advanced Cooperative Lidar Experiment: a joint study of NASA/LaRC and the Canadian Space Agency) and WALES (Water vApor Lidar Experiment in Space: a study by the European Space Agency). One crucial aspect determining spaceborne DIAL performance is the collecting telescope's aperture size. In this respect, the interests of the atmospheric remote sensing and the astronomy communities overlap, in that spaceborne telescope aperture size is a key performance driver for both applications. While the stringent optical performance requirements characteristic of astronomical instruments -and the success seen in reaching some of these goals for the Next Generation Space Telescope (NGST)- are encouraging for the realization of more modest spaceborne lidar telescope optical performance requirements, spaceborne DIAL telescope development nevertheless provides its own challenges.
