Short summary
It is shown that during a satellite-to-satellite radio transmission, over the Earth's limb, the signal bounced off the ocean contains information of the low atmosphere as shown with radio occultations. This bounced signal is particularly clear over colder oceans but less clear over the tropics. This information is indicative of the properties of the low troposphere and can be used as a remote sensing measurement for weather.
