The Weatherlink samples the temperature reading from the station a number of times during the interval and then averages all those readings to arrive at the average temperature for the interval. The number of times the Weatherlink samples the temperature depends on the archive interval.
Archive Interval Sample Rate
The first time the Weatherlink samples the outside temperature during the interval it writes that value into both a high and low register in memory. Every subsequent time the Weatherlink samples the temperature, it compares the current value to the value in the registers and if the current value is higher or lower, replaces the old value with the current value.

These descriptions were taken from the "ReadMe" file included with the Davis Instruments, Weather Link software package. The descriptions have been modified to suit the specifics of our implementation.
When error correction is selected the search is against data that was checked with a moving average of 24 entries with any data greater than 6 standard deviations from the moving average removed. This error correction was done to try and remove any instrumental anomalies from the data. Our error correction is automated and it should not be assumed that any data that was thrown out has been checked by human eyes. If you want the raw information returned from your search, turn off the error correction in the search options.
