Quantitative Precipitation Estimation of Extremes in CONUS With Radar Data

Constructing an accurate, continental, in-situ-based, kilometer-scale, long-term record of the precipitation field and its spatiotemporal changes remains a significant challenge. Here, we determine extreme-value behavior NEXRAD Stage IV radar-based quantitative estimate. We find that climatology 5-year daily return values in contiguous United States East Rocky Mountains shows only slight variability on spatial scales smaller than 100 km. In light this finding, test whether rain-gauge-only data sets can produce accurate at finer spacing between gauges. are locations far from rain gauges if interpolation is carried out appropriately for extremes. Precipitation statistics derived in-situ gauge therefore sufficient resolution to faithfully capture extremes over much eastern States.
