使用激光雷达技术的卫星遥感为全球大气物种（如二氧化碳、臭氧、云、气溶胶）、大气物理属性（如温度、风速）和地球特征光谱指标（如植被、水）的三维绘图提供了一个强有力的工具。这些信息为天气预报、了解气候变化、大气科学和地球生态系统的健康提供了宝贵的来源。同样，激光测高可提供高精度的地面地形测绘和更复杂的三维测绘（如冠层高度剖面）。激光雷达技术需要使用尖端激光技术和工程设计，这些技术和设计必须能够在使命寿命期内经受住空间环境的考验。激光器必须以适当的高电光效率运行，并采用风险降低策略以减轻激光器故障或激光器性能的过度运行降级。
Satellite-based remote sensing using laser-based lidar techniques provides a powerful tool for global 3-D mapping of atmospheric species (e.g. CO2, ozone, clouds, aerosols), physical attributes of the atmosphere (e.g. temperature, wind speed), and spectral indicators of Earth features (e.g. vegetation, water). Such information provides a valuable source for weather prediction, understanding of climate change, atmospheric science and health of the Earth eco-system. Similarly, laser-based altimetry can provide high precision ground topography mapping and more complex 3-D mapping (e.g. canopy height profiling). The lidar technique requires use of cutting-edge laser technologies and engineered designs that are capable of enduring the space environment over the mission lifetime. The laser must operate with suitably high electrical-to-optical efficiency and risk reduction strategy adopted to mitigate against laser failure or excessive operational degradation of laser performance.
