TLDR
In this article, a new method for the identification of tropopause heights from GPS radio occultation (RO) bending angles (α ) was proposed, which uses a covariance transform to identify transitions in a ln ( α ) profile.About:

Exploring earth's atmosphere with radio occultation: contributions to weather, climate and space weather
TL;DR: In this article, the authors summarized results from radio occultation (RO) observations and the applications of RO observations to atmospheric research and operational weather analysis and prediction, as well as the theoretical capabilities of RO to provide accurate and precise profiles of electron density in the ionosphere and refractivity, containing information on temperature and water vapor, in the stratosphere and troposphere.
