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 کاملThe Assimilation of Radio Occultation Measurements
GPS radio occultation (RO) measurements are a potentially important new source of profile information that can be used in numerical weather prediction (NWP). This paper outlines the options for assimilating the RO measurements into an operational NWP system. The importance of realistic estimates for the observation error estimates is discussed.

متن کاملProcessing X/K band radio occultation data in the presence of turbulence
[1] Canonical transform (CT) and full-spectrum inversion (FSI) methods can be used in processing radio occultation data to retrieve transmission profiles, which are necessary in addition to bending angle profiles for the retrieval of atmospheric humidity independent of temperature. Low Earth orbiter–low Earth orbiter cross-link occultations with X/K band frequencies can provide transmission dat...
متن کاملCanonical transform method for processing radio occultation data in the lower troposphere
[1] The methods of processing radio occultation data in multipath zones which were used up to now have very strong restrictions of the applicability. In this paper, we introduce a new approach to the problem of deciphering the ray structure of wave fields in multipath zones using the short-wave asymptotic solution of the wave problem. In geometric optics a canonical transform resolves multipath...
