Abstract

To evaluate spatial representativeness of historical air-temperature records, a modified geostatistical procedure was developed. The procedure measures the spatial representativeness of a station based on variogram parameter estimates, in this case the nugget. This application is novel for 2 reasons : variogram models are fit to station specific or point centered semivariance, and variogram models are fit to semivariance computed at intervals in a time series. Examples from the central-U.S. subset of the Daily Historical Climatology Network illustrate how anomalous nuggets or step changes in nuggets can be identified relative to station changes
