The dataset contains daily nc-files of the Cloudnet target classification during Polarstern cruise PS106 based on:- 35.5 GHz Cloud radar MIRA,- PollyXT,- https://www.ready.noaa.gov/gdas1.php using output produced by the profile binary in the HYSPLIT offline package,- OceanRAIN optical disdrometer ODM470,- Microwave radiometers.The data is retrieved using the instrument synergystic approach Cloudnet (Illingworth, 2007, doi:10.1175/BAMS-88-6-883).This variable is a simplification of the bitfield \"category_bits\" in the target categorization and data quality dataset.It provides the 9 main atmospheric target classifications that can be distinguished by radar and lidar.Target_classification:definition = 0: Clear sky, 1: Cloud droplets only, 2: Drizzle or rain, 3: Drizzle/rain & cloud droplets, 4: Ice, 5: Ice & supercooled droplets, 6: Melting ice, 7: Melting ice & cloud droplets, 8: Aeroso, 9: Insects.
