Abstract
This water vapor observation device comprises an antenna, an RF amplifier, and processing circuitry. The antenna receives radio waves radiated from an atmosphere including water vapor. The RF amplifier amplifies the received radio waves and generates an observation signal. The processing circuitry is programmed to at least: use the observation signal to select a plurality of observation frequencies excluding an accuracy degraded frequency; and calculate a water vapor index using the spectral intensities of the plurality of observation frequencies. This configuration makes it possible to accurately observe a water vapor amount.
