The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations Night Validation Flights (CALIPSO-NVF) was a NASA campaign that focused on the validation and calibration of CALIPSO’s nighttime aerosol retrievals. CALIPSO-NVF had one deployment that consisted of five nighttime flights across Bermuda during August 2022. NASA Langley’s B-200 aircraft was equipped with the High Spectral Resolution Lidar 2 (HSRL-2) to collect measurements of aerosol optical properties for satellite validation purposes.
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).
