The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations Night Validation Flights (CALIPSO-NVF) was a NASA campaign focused on validating and calibrating CALIPSO’s nighttime aerosol retrievals. CALIPSO-NVF had one deployment, consisting of five nighttime flights over Bermuda in August 2022. NASA Langley’s B-200 aircraft was equipped with the High Spectral Resolution Lidar 2 (HSRL-2) to gather measurements of aerosol optical properties for satellite validation.
The High Spectral Resolution Lidar 2 (HSRL-2) is an airborne lidar developed by NASA's Langley Research Center. HSRL-2 measures aerosol backscatter at 355, 532, and 1064 nm wavelengths and aerosol extinction at 355 and 532 nm wavelengths. It has a horizontal resolution of 1-2 km and a vertical resolution of 15 m, with measurements taken approximately every 0.5 seconds. It replaced the original High Spectral Resolution Lidar (HSRL).
