Neighboring Stations

This is a list of stations that are close to this station. You can look at those for comparison purposes. The average difference between your station and each station below is listed as well. This may allow you to detect local stations which are erroneous. You can also use these numbers to adjust your instruments -- especially if a number of ASOS stations have similar differences to your station. Also, try increasing the analysis period to more than the default 28 days. The difference is only given if both stations report reasonably often during each day. Some stations only report every 6 hours, and this makes the average of less interest. In this case, the average is not displayed. The values reported are the differences between this station and the neighboring station. I.e. if the difference is positive, then this station is reading higher than the neighboring station. Since this station has not been reporting continuously during the analysis period (it missed 6 days out of 7), the offsets below may not be accurate.
