Cumulative precipitation and snow depth accumulation during the SnowEx Alaska March 2023 Intensive Observing Period (IOP) and historical averages at the UKT study area. Cumulative daily precipitation in 2022–2023 (blue solid line) is plotted alongside average cumulative daily precipitation from 1991–2020 (green dashed line, Imnaviat [sic] SNOTEL). The March 2023 IOP magnaprobe snow depths collected at the UKT study area are plotted as a box and whisker plot to highlight the large range of snow depth variability (0–190 cm). The boxplot also shows that most of the snow depth falls within the 34–54 cm range (2nd and 3rd quartiles) with 45 cm of median snow depth. Seasonal snow depths recorded by two automated weather stations (US-ICs and US-Ich fall within the 2nd and 3rd quartile, while snow depth at automated weather station UKmet represents snow drift) (dashed orange, purple, and black lines).
