The Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) is a two-wavelength lidar that provides high-resolution vertical profiles of aerosols and clouds. CALIOP is one of three instruments aboard the joint NASA/French Space Agency Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite, which launched in 2006. CALIPSO provides insight into the role that clouds and atmospheric aerosols play in regulating Earth's weather, climate, and air quality.
