The microwave radiometers HATPRO (Humidity and Temperature Profiler) and MiRAC-P (Microwave Radiometer for Arctic Clouds - Passive) continuously measured radiation emitted from the atmosphere throughout the Multidisciplinary drifting Observatory for the Study of the Arctic Climate (MOSAiC) expedition on board the research vessel Polarstern. From the measured brightness temperatures, we have retrieved atmospheric variables using statistical methods in a temporal resolution of 1 s covering October 2019 to October 2020. The integrated water vapour (IWV) is derived individually from both radiometers. In addition, we present the liquid water path (LWP), temperature and absolute humidity profiles from HATPRO. To prove the quality and to estimate uncertainty, the data sets are compared to radiosonde measurements from Polarstern. The comparison shows an extremely good agreement for IWV, with standard deviations of 0.08-0.19 kg m (0.39-1.47 kg m) in dry (moist) situations. The derived profiles of temperature and humidity denote uncertainties of 0.7-1.8 K and 0.6-0.45 gm in 0-2 km altitude.
微波辐射计 HATPRO（湿度和温度廓线仪）和 MiRAC-P（北极云微波辐射计-被动）在极地星号研究船上的北极气候多学科漂移观测站（MOSAiC）考察期间，持续测量了大气发射的辐射。从测量的亮温中，我们使用统计方法以 1 秒的时间分辨率检索了大气变量，时间范围涵盖 2019 年 10 月至 2020 年 10 月。这两个辐射计各自独立地得出大气水汽总量（IWV）。此外，我们还展示了 HATPRO 的液态水路径（LWP）、温度和绝对湿度廓线。为了证明质量并估计不确定性，将数据集与极地星号上的无线电探空仪测量值进行了比较。比较结果表明，IWV 具有极好的一致性，在干燥（潮湿）条件下的标准偏差为 0.08-0.19kgm（0.39-1.47kgm）。0-2km 高度范围内温度和湿度廓线的不确定性分别为 0.7-1.8K 和 0.6-0.45gm。
