Fig. 6From: Comparison of shipborne GNSS-derived precipitable water vapor with radiosonde in the western North Pacific and in the seas adjacent to Japan a Time sequence of PWV for the entire observation period (green line: retrieved from the MAST measurements, led line: same with green line but rejected through the quality control procedure, black circles: radiosonde). Thick gray line represents latitude of the vessel. b Anomaly plots of GNSS PWV from the MAST measurements against radiosonde observations. Two red circles are rejected through the quality controlBack to article page
