GPS Meteorology

GPS meteorology refers to the use of the effect of the atmosphere on the propagation of the Global Positioning System's (GPS) radio signals to derive information on the state of the (lower, neutral) atmosphere.

There are currently two main operational techniques in use in GPS meteorology: GPS limb sounding from orbit, and GPS water vapour monitoring.
