Abstract

Over the past 40 years, dew point measurement techniques have changed. From human measurements to automated instruments, and the implementation of uniform ASOS stations, the way dew points have been measured has changed immensely. These changes in types of measurements have an unknown effect on the dew point record. It is possible that these changes could skew the dew point trend over long periods of time. These changes are especially important when assessing climate changes. If differences exist, a reliable method of assessing the differences could be developed. This study assesses the differences in dew point measurement techniques and their effect on the resulting measurements.
