CWOP Miscalibration Report

This is the list of sites whose Barometric Pressure readings (over the last 28 days) have a large mean error, but a small standard deviation. This indicates a probable calibration error, which could, presumably, be fixed.

In some many cases it appears that the alitutude adjustment has not been made. If the adjustment is made, then the error becomes the value in the 'Alt Adj Error' column. This shows a dramatic improvement for many sites.

The 'best fit slope' column is indicative of a problem if the value is not close to 1.000. This is the calculated best fit multiplier to get from reading to analysis value.

The CWOP Information page contains a great deal of useful information about setting up your weather station.
