<Summary>These Level-3 data provides measurements from the dropsonde launches made by HALO and Polar-5 aircraft during the HALO-(AC)³ field campaign in March-April, 2022 over the Norwegian and Greenland Seas, the Fram Strait, and the central Arctic Ocean. The file contains merged data of soundings from both aircraft and is generated from the Level-2 data (doi:10.1594/PANGAEA.968896) as described in Ehrlich et al (in prep). ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.968900"!</Summary>
