The Differential Absorption Lidar (DIAL) - High Spectral Resolution Lidar (HSRL) is an airborne lidar that implements both the DIAL and HSRL lidar techniques to measure ozone and aerosols simultaneously. DIAL operates typically at the 289 nm and 300 nm wavelengths to measure ozone profiles. The HSRL modification adds a 3-wavelength (355 nm, 532 nm, 1064 nm) narrowband laser to the DIAL system allowing for the measurements of aerosol backscatter, aerosol extinction, depolarization, and other aerosol properties. For ozone measurements, DIAL-HSRL has a typical vertical resolution of 330 m with a temporal resolution of 90 seconds. For aerosol measurements, it has a typical vertical resolution of 30 m with a temporal resolution of 10 seconds.
