Triple Collocation Analysis of GNSS, MWR, and Radiosonde Water Vapor Retrievals Across Dry and Wet Seasons: A 2025–26 Analysis at Nicosia, Cyprus
Integrated Water Vapor (IWV) is a key indicator of atmospheric moisture, and its accurate quantification requires precise characterization of the errors inherent to each observing system, a task complicated by the absence of a true, error-free atmospheric reference. This study characterizes the absolute error structure...
