a relative uncertainties in gridded (boxplots) and basin-wide (solid red line) estimations of the long-term mean (top panel) and the trend (bottom panel) of SWA across 25 drainage regions in Canada and Alaska; spatial structure of relative uncertainties in estimations of the gridded b long-term mean and c trend of SWA, quantified through dependencies with longitude, latitude and elevation. Drainage regions, where significant dependencies exist between SWA estimates and spatial elements (p-value ≤ 0.05), are colored in both panels. Color saturations correspond with the absolute value of Kendall’s tau. Drainage regions with negative dependencies between relative uncertainty and spatial elements are marked with asterisks (*). Drainage regions where dependencies are not significant are sliced out and remained uncolored.
