Specific humidity profiles derived from the combination of low- and high-frequency microwave radiometer measurements on Polarstern cruise PS144

This data set contains daily files of specific humidity profiles derived from combined measurements of the low- and high-frequency microwave radiometers HATPRO (Humidity And Temperature PROfiler, Rose et al., 2005) and MiRAC-P (Microwave Radar/Radiometer for Arctic Clouds - Passive, Mech et al., 2019) on Polarstern cruise PS144 (Rabe & Geibert, 2025). The data set covers the date range from 12 August to 7 October 2024 and is limited to 0-10000 m height above the instrument. The specific humidity profile retrieval is based on a Neural Network whose configuration and training is described in Walbröl et al. (2024). The effective vertical resolution of the specific humidity profile is 600 m at the surface and increases to 7500 m at 10000 m height (Walbröl et al., 2024).
