Abstract. Lidar (light direction and ranging) is a laser remote sensing technique of special importance in atmospheric science, and is the optical equivalent of radar. Lidars can obtain profiles of temperatures, winds, constituents (e.g., ozone, water vapour), and particulate (e.g., cloud, aerosol) optical properties, amongst others, at high spatial and temporal resolutions. Ground-based lidar have been used since the 1960s, and recent years have seen the advent of space-based systems. Canada has played a key role in these developments, and continues to advance new lidar technologies for atmospheric research. This paper provides a brief overview of Canadian accomplishments in the context of the broader field, and describes new avenues of research for the future, on both Earth and Mars.
