The University of Western Ontario's Purple Crow Lidar (PCL) measures temperature and composition of Earth's atmosphere from the surface to 110 km altitude. The PCL is able to make these measurements at unprecedented accuracy by using a 2.65 m diameter liquid mirror telescope. The liquid mirror is a Canadian technology which allows large mirrors to be built at a fraction of the cost of traditional glass mirrors. The long-term objectives of this research program are to search for atmospheric change and to help improve weather forecasting.

西安大略大学的紫鸦激光雷达（PCL）测量从地表到海拔110公里的地球大气的温度和成分。PCL能够使用直径2.65米的液体反射镜望远镜以前所未有的精度进行这些测量。这种液体镜子是加拿大的一项技术，它可以以传统玻璃镜子的一小部分成本建造大型镜子。这项研究计划的长期目标是寻找大气变化并帮助改进天气预报。
