In recent years, the global positioning system (GPS) has been exploited via radio occultation
techniques to obtain profiles of refractivity, temperature, pressure and water vapor in the …

Abstract The Constellation Observing System for Meteorology Ionosphere and Climate
(COSMIC) is a satellite mission for the Earth sciences that will make use of recent …

Radio occultation observations represent a planetary-scale optics experiment in which the
atmosphere acts as a lens and alters the propagation velocity and paths of microwave …

A one‐dimensional bending‐angle observation operator for assimilating GPS radio
occultation (RO) measurements has been integrated into the ECMWF four‐dimensional …

ABSTRACT The GPS/MET (Global Positioning System/Meteorology, Ware et al. 1996)
project demonstrated atmospheric limb sounding from low-earth orbit (LEO) with high …

With the availability of approximately 4,000 radio occultation soundings per day within three
hours of observation, COSMIC has the potential to contribute significantly to global and …

Applications for space‐based GPS technology have extended to the atmospheric field
during the last two decades. More recently, numerical weather prediction (NWP) centers …

We compare the random error statistics (uncertainties) of COSMIC (Constellation Observing
