Reconstructed North American Snow Extent, 1900-1993  View Catalog Page Entry ID
G02130
Summary
This data set contains reconstructed monthly North American snow extent values for November through March, 1900-1993. Investigators used a combination of satellite and station observations and based the reconstruction on linear regressions between the two types of observations. The data also includes standard errors of estimates as well as the observed values upon which the regressions were based.
Station-based snow observations are available for dates since the early twentieth century but lack comprehensive spatial coverage. A remotely sensed product based on visible-band imagery provides more complete spatial coverage but has only been available since the early 1970s. Since the reconstructed values are based on regression, variability is underestimated and therefore the magnitude of some extreme values is underestimated.
Data are available via FTP.

Quality
Since the method is based on regression, variability is underestimated and therefore the magnitude of some extreme values is underestimated. However, in no case during the satellite era, when data collected both by satellite and at stations were available, was the sign of the reconstructed deviation from the mean different than observed.
