This data set includes ground surface temperatures and air temperatures measured at ten study plots within the Kuparuk River basin of north-central Alaska. Computed thaw-season 'n-factor' values are also included (the n-factor is defined as the ratio of the sum of thawing degree days at the soil-surface to that in the air). Data were collected in an effort to evaluate differences between air and ground-surface temperatures associated with different natural landcover types, and to assess the utility of the 'n-factor' concept as a tool in geocryological mapping. Detailed descriptions of field procedures and assumptions are provided in Klene (2000) and Klene et al. (2001).
