We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

NightBLUE
Nighttime Bermuda Lidar Underflights of EarthCARE
In September 2025, the Nighttime Bermuda Lidar Underflights of EarthCARE (NightBLUE) field campaign completed 16 underflights to support validation of data from the Earth Cloud, Aerosol and Radiation Explorer (EarthCARE) satellite, particularly the (ATLID) atmospheric lidar.
To support the NightBLUE campaign, researchers flew the NASA High Spectral Resolution Lidar-2 (HSRL-2) onboard the NASA G-III aircraft. Eleven underflights were completed at night and 5 were completed during daytime. The 100th underflight of EarthCARE was completed during NightBLUE.
EarthCARE is a satellite mission implemented by the European Space Agency (ESA), in cooperation with the Japan Aerospace Exploration Agency (JAXA), to measure global profiles of aerosols, clouds, and precipitation properties together with radiative fluxes and derived heating rates.
