The Differential Absorption Lidar (DIAL) - High Spectral Resolution Lidar (HSRL) is an airborne lidar that combines both DIAL and HSRL techniques to measure ozone and aerosols at the same time. DIAL typically operates at wavelengths of 289 nm and 300 nm to profile ozone. The HSRL modification adds a three-wavelength (355 nm, 532 nm, 1064 nm) narrowband laser to the DIAL system, enabling measurements of aerosol backscatter, extinction, depolarization, and other aerosol properties. For ozone measurements, DIAL-HSRL generally has a vertical resolution of 330 m and a temporal resolution of 90 seconds. For aerosol measurements, it features a vertical resolution of 30 m and a temporal resolution of 10 seconds.
