Backpropagation Processing of GPS Radio Occultation Data
We provide an assessment of the backpropagation (BP) method for processing GPS radio occultations using simulations as well as recent data from CHAMP and SAC-C. It is found that BP gives improved retrievals over the standard Doppler technique, even when multipath ambiguities are not completely removed. In addition, by being an amplitude-weighted algorithm, BP is robust in the presence of receiv...

متن کاملPotential Impact of COSMIC GPS Radio Occultation Data on Regional
A major challenge for operational numerical weather prediction over the Antarctic and Southern Ocean is the lack of traditional meteorological observations. This increases uncertainty in the model initial condition and results in inferior forecast skills as compared with numerical weather prediction in mid-latitudes over the Northern Hemisphere. With the lack of traditional observations over th...
متن کاملAssimilation of GPS Radio Occultation Data for Numerical Weather Prediction
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 regional weather analysis and prediction. However, the basic radio occultation measurements (phase delays) are very different from traditional meteorological measurements (i.e., temperature, water vapor), and to ef...
متن کاملAtmosphere sounding using GPS radio occultation
Introduction On July 17, 1995 the U.S. Air Force announced “ .. that today the Global Positioning System (GPS) satellite constellation has met all requirements for Full Operational Capability”. Apart from precise positioning GPS signals also can be used to derive characteristic properties of the propagation medium (neutral atmosphere and ionosphere). Onboard the Low-Earth-Orbiting MICROLAB-1 sa...
