Snow cover and snowmelt of an extensive High Arctic wetland: spatial and temporal seasonal patterns

摘要: Abstract This study examined the end-of-winter snow storage, its distribution and spatial temporal melt patterns of a large, low gradient wetland at Polar Bear Pass, Bathurst Island, Nunavut, Canada. The project utilized combination field observations physically-based snowmelt model. Topography wind were major controls on in region, was routinely scoured from hilltop regions deposited into hillslopes valleys. Timing duration Pass similar 2008 2009. initiated by an increase air temperature net radiation receipt. Inter-annual variability evident attributed to non-uniform cover local microclimate conditions. In situ studies modelling remain important High Arctic for assessing water budgets runoff, addition model parameterization validation satelli...
