Abstract
We have developed a state-of-the-art microwave radiometer named KUMODeS (KEK Universal Moisture and Oxygen Detection System) using millimeter-wave spectroscopy in order to monitor water vapor behavior. We have carried out comparative measurements of precipitable water vapor (PWV) in order to investigate the potential of KUMODeS/PWV measurements. Although further investigation is required to evaluate the performance of KUMODeS quantitatively, the preliminary results of PWV comparisons imply that the KUMODeS technology will be useful for retrieving the accurate behavior of water vapor with high temporal resolution.
