Air Temperature and Thaw Depth, North Slope, Alaska: Field Measurements (1995-97) and Computed Values  View Catalog Page Entry ID
ARCSS040
Summary
This data product contains field data measurements of air temperatures and thaw depth (active-layer thickness) measured at locations in north-central Alaska, and modelled values of air temperatures and thaw depth extrapolated to an area encompassing the Kuparuk River basin of north-central Alaska. Air temperature and thaw depth were measured in the years 1995, 1996, and 1997; air temperature was measured at 10 core Flux Study plots and additional sites, and thaw depth was measured within each of seven ARCSS 1 km x 1 km grids. The data were collected to provide a basis for extrapolating thawing degree-days and thaw depth to the landscape scale (the Kuparuk River basin).
Modelled air temperatures derived from the 1995 air temperature measurements are represented in 787 x 371 element matrices of thawing degree-day sums at weekly intervals for part of summer 1995. Thaw depth matrices were modelled using the interpolated thawing degree-day data, a vegetation map of the Kuparuk River basin, and a digital elevation model (DEM) of the same area. Modelled thaw depth is represented in 178 x 369 element matrices of active-layer thickness at weekly intervals for part of summer 1995, one time period in 1996, and 'end-of-season' (August 6) 1997.
