Long Term Snow Data Comparison - Systematic Bias

Long Term Snow Data Comparison - Systematic Bias

There is both systematic and random bias inherent in snow data. These biases may have a significant impact on the comparisons of current data versus other time periods. Failure to quantify and adjust for this bias may yield incorrect or biased conclusions regarding trends in snow data. The files here illustrate SOME of these biases. Those using these data should contact Snow Survey Personnel for a more complete discussion of individual stations.
