The GNSS-RO instrument's receivers track navigation satellite radio signals as they dip below, or rise from, the horizon. They can detect these signals through the vertical extent of the atmosphere – through thick clouds – from the very top and almost all the way to the ground. This is important, because weather phenomena emerge from all layers of the atmosphere, not just from near Earth's surface where we experience their effects.

"Tiny changes in the radio signal can be measured by the instrument, which relate to the density of the atmosphere," added Ao. "We can then precisely determine the temperature, pressure, and humidity through the layers of the atmosphere, which give us incredible insights to our planet's dynamic climate and weather."

At last, an independent way to check RSS data. Some climate change deniers have been using RSS data and curious software to report different results than pretty much anyone else. But this method of refractive measurements will provide slices, almost like a CAT scan of what is going on in the atmosphere.
