Sampling and statistical analyses of BTS measurements
Basal temperature of snow (BTS) data show characteristic spatial autocorrelations at distances typically less than 200m, leading to non-independent regression residuals. Systematic temporal variations may also introduce model bias resulting in a shift in the predicted lower limit of permafrost. Both...

Summary: | Basal temperature of snow (BTS) data show characteristic spatial autocorrelations at distances typically less than 200m, leading to non-independent regression residuals. Systematic temporal variations may also introduce model bias resulting in a shift in the predicted lower limit of permafrost. Both phenomena are analysed. The selection of an appropriate sampling design for a BTS measure-ment program appears critical in order to minimize problems typical of observational data in complex |
