Short summary
In this paper we analyze GNSS radio occultation measurement data from the MetOp-A satellite using a particular operator called phase matching. We find that reflected GNSS signals can be distinguished using this method and that there are structures that differ significantly from simulated measurements. Making radio occultation measurements in the lower troposphere is difficult, and the motivation of this study is to investigate different ways of addressing this problem.
