Abstract [1] The terrestrial Arctic water cycle is strongly influenced by the presence of
permafrost, which is at present degrading as a result of warming. In this study, we describe
improvements to the representation of processes in the pan-Arctic Water Balance Model
(PWBM) and evaluate simulated soil temperature at four sites in Alaska and active-layer
thickness (ALT) across the pan-Arctic drainage basin. Model improvements include new
parameterizations for thermal and hydraulic properties of organic soils; an updated snow ...
