Abstract
A microwave radiometer includes an electromagnetic wave transmission surface, a vertically upward horn configured to receive an electromagnetic wave passing through the electromagnetic wave transmission surface and processing circuitry configured to generate water vapor spectrum data relating to water vapor based on the electromagnetic wave received by the horn, generate cloud liquid water data relating to cloud liquid water based on the electromagnetic wave received by the horn, and calculate a water vapor amount by using the water vapor spectrum data and the cloud liquid water data.
