Research Abstract

We have developed a chilled mirror hygrometer for the climate monitoring, which accurately measures atmospheric water vapor from the surface to the lower stratosphere. Additionally, we re-evaluated the relative humidity measurement uncertainty of the RS-06G operational radiosonde, and developed a cloud particle sensor for balloon sounding. These measurement systems can make more reliable and stable water vapor measurements.
