Comparison of the IWV from MOSAiC radiosondes (see text for details) with retrieved IWV from HATPRO (a) and MiRAC-P (b). The MWR data has been averaged over 15 minutes starting from each radiosonde launch time. The error bars denote the standard deviations of the 15-minute periods. A linear fit has been determined for both radiometers (coloured solid line) and a perfect fit is provided for orientation. Additionally, the number of samples (N), mean, bias, root mean squared error (RMSE), standard deviation (std.), and Pearson correlation coefficient (R) are given.
