Abstract Calibration of satellite observations is crucial for ensuring the quality retrieved products essential meteorological and climate applications. obtained monitored through a cascade stages, including postlaunch vicarious calibration/validation activities comparison with independent reference measurements. Here, calibration method using radiative transfer simulations based on radiosondes considered in framework Microwave Imager (MWI) Ice Cloud (ICI) to be launched Second Generation EUMETSAT Polar System. This paper presents an overview uncertainty characterizing MWI ICI as performed within EUMETSAT-funded VICIRS study. The characterization pursued following metrological approach, providing preliminary estimation all identified sources. same approach used develop rigorous estimating number pairs (i.e., vs. simulations) needed reach certain level accuracy bias determination.
