[MIS24-P04] Measurement of precipitable water vapor using small and lightweight microwave radiometer
Keywords:microwave radiometer, precipitable water vapor
As the reference data, we use the radiosonde data which launched from Shionomisaki Weather Station, Japan Metrological Agency. The measured data is provided by the Integrated Global Radiosonde Archive. Note that, we also use the radiosonde data launched from Shionomisaki Wind Effect Laboratory. The measurement durations of radiosonde from the laboratory are 11-20th, Oct and 5-15th, Nov, 2018. Additionally, we also use GNSS system (RTNet, Hitachi Zosen, Osaka, Japan) as the reference data. The PWV is estimated by the Zenith Tropospheric Delay, pressure and temperature at measurement location. The PWV estimated using proto-radiometer shows the good agreement with the reference data except for rainfall duration. The results indicate that the small and lightweight proto-radiometer can measure the PWV correctly.
