| Outline of Final Research Achievements |
For early prediction of localized heavy rainfall that can cause extensive damages, we have developed a compact lidar that continuously measures the vertical distribution of water vapor density in the lower troposphere. The lidar is compact and light weight by employing a laser diode and amplifier for the transmitter. The result of test measurements in the summer of 2016 in Tokyo showed that it can measure the vertical distribution of water vapor between 0.6 and 3 km in night and 0.6 and 1.3 km in day with temporal resolution of 10 minutes and vertical resolution of 150 m. The lidar is shown capable of continuous operation over a month.
