Simplified Generation of Radio Occultation Climatologies
The possibility of simplifying the retrieval scheme required to produce GNSS radio occultation refractivity climatologies is described. In a new, simplified retrieval approach, the main statistical analysis is performed in bending angle space and an estimate of the average bending angle profile is then propagated through an Abel transform. The average is composed of means and medians of ionosph...
متن کاملSmoothing radio occultation bending angles above 40 km
The ‘statistically optimal’ approach to smoothing bending angles derived from radio occultation (RO) measurements is outlined. This combines a measured bending angle profile with an a priori or background estimate derived from climatology, in order to obtain the most probable bending angle profile. However, the method is only optimal if the error statistics of both the measured and background p...

متن کاملSimulation studies of GPS radio occultation measurements
The atmospheric propagation of GPS signals under multipath conditions and their detection are simulated. Using the multiple phase screen method C/A-code modulated L1 signals are propagated through a spherically symmetric refractivity field derived from a high-resolution radio sonde observation. The propagated signals are tracked by GPS receivers implemented in software and converted to refracti...
