Data accompanying the research on Relation between Signal of Microwave Link and Water vapor

Three horizontal polarization MLs at 15, 18 and 23 GHz are applied for studying the potential of sensing the water vapor in Jiangyin, China from March 26 to April 20, 2019. The attenuation signal can be measured by the ML with the measurement resolution of 0.1dB and the sample time of 1 minute. Meanwhile, three hydrological gauges are installed near the MLs, which can measure the water vapor density (resolution: 1 g/m3) and the rainfall depth (resolution: 0.5 mm) with 5-minute sample time.
