Dropsonde measurements from HALO and POLAR 5 during HALO-(AC)³ in 2022 (Level-1)

These Level-1 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. Each file contains data from a single sounding. The file is generated by processing the raw data (Level-0) with state-of-the-art ASPEN software (Atmospheric Sounding Processing ENvironment, v4.0.0) which runs basic quality control and removes erroneous soundings and/or measurements therein.
