Quality Spread Distribution Page

This page shows the overall state of the stations that have signed up for weather quality emails. It shows the mean error and the standard deviation for their readings. The worst 5% of stations are not plotted (otherwise the outliers mess up the autoscaling). The period of the analysis is the last 14 days.

Note that the error is "analysis - observed". I.e. if the error is positive, then this means that the reading was less than the expected value.
