HSRL-2
High Spectral Resolution Lidar 2

The Second Generation High Spectral Resolution Lidar (HSRL-2) is an airborne lidar developed by the NASA Langley Research Center. HSRL-2 measures aerosol backscatter at the 355, 532, and 1064 nm wavelengths and aerosol extinction at the 355 and 532 nm wavelengths. It has a horizontal resolution of 1-2 km and a vertical resolution of 15 m, and it takes measurements roughly every 0.5 seconds. It replaced the High Spectral Resolution Lidar (HSRL).
