Design and Implementation of a Real-time Radiosonde Location System for Upper-air Observations

Abstract

A radiosonde is a piece of equipment for analyzing changes in the atmosphere in three dimensions from the ground up to a maximum altitude of 3,500 meters. The radiosonde moves through the upper air at 5 m/s and collects upper-air data, such as atmospheric pressure, temperature, wind direction and wind speed. The upper-air data is used as basic research data for improving weather forecasts and handling climate change. However, handling climate change in real-time is difficult because the collected upper-air data from the radiosondes are transmitted to the World Meteorological Organization after completion of the flights. To resolve this problem, this paper proposes the design and implementation of a real-time radiosonde location and representation system to improve atmospheric analysis of upper-air observations.
