Arctic EASE-Grid Freeze and Thaw Depths, 1901 - 2002

Entry ID: ggd651

[ Update this Record ]

Summary

Abstract: This data set contains mean, median, minimum and maximum freeze and thaw depths for each year from 1901 to 2002 on the 25 km resolution Equal-Area Scalable Earth Grid (EASE-Grid) for areas north of 50 deg. Freeze and thaw depths are estimated using a variant of the Stefan solution using an edaphic factor and freezing or thawing indices as inputs. The edaphic factor is estimated based on ...

GEOSCIENTIFIC INFORMATION

Quality The relationship between freeze/thaw depth and freezing and thawing indices has been demonstrated in several places. For example, Brown et al. (2000) review the relationship between thaw depth and the annual thawing index. Romanovsky and Osterkamp (1995), Zhang et al. (1997), Nelson et al. (1998), Klene et al. (2001), and Hinkel and Nelson (2003) all demonstrate the general validity of the ...
