Definition

Radio Occultation (RO) : a satellite-based measuring technique providing globally distributed datasets of vertical profiles for atmospheric parameters such as density, pressure, temperature, and water vapor.

Introduction

In order to prove or disprove research arguments used in the discussions of climate change, large globally distributed datasets over a sufficiently large time interval are essential. In this respect, the radio occultation method, a satellite-based measuring technique, first suggested by a group at Stanford University in 1962, provides a globally distributed dataset of vertical profiles of a variety of atmospheric parameters such as density, pressure, temperature, and water vapor. Several satellites equipped with measuring instruments were launched into the Earth’s atmosphere; one of them was the German CHAllenging Minisatellite Payload (CHAMP) , which also provided the data used in this work. The radio occultation method, e.g., based on CHAMP data, has...
