Abstract
An apparatus, method, and program capable of predicting an attenuation of electromagnetic waves in an upper airspace of a target area in consideration of the influence of long-term weather changes in future are provided. An apparatus for predicting an attenuation of electromagnetic waves between a radio apparatus located above a target area and a terrestrial surface is provided with a data acquisition section for acquiring past weather data in the target area, and an estimation section for estimating a weather corresponding to a future target year in the upper airspace of the target area based on the past weather data, and estimating an attenuation of electromagnetic waves based on an estimation result of the weather.
