MARLi
Multi-function Airborne Raman Lidar

The Multi-function Airborne Raman Lidar (MARLi) is an airborne lidar that collects profiler measurements within the planetary boundary layer (PBL). It operates at 355 nm and/or 266 nm to detect Raman lidar signals and measure profiles of temperature, water vapor mixing ratio, aerosols, and clouds. It has a horizontal resolution ranging from approximately 100 m to 1 km and a vertical resolution of 60 cm. MARLi has a measurement sampling rate of 10 Hz.
