The Andes Lidar Observatory is a National Science Foundation Upper Atmosphere Facility located on Cerro Pachón in Chile. Its main mission is to make detailed measurements of the upper atmosphere (80 to 110 km) above the Andes, with a suite of ground-based remote sensing instruments. 

This observatory houses several passive optical instruments, including a Mesosphere Temperature Mapper, an Infrared Imager, a near-infrared All Sky Imager, and a meteor radar.
