Wave Optics Algorithms for Processing Radio Occultation Data in the Lower Troposphere: A Review and include back propagation and canonical transform methods. Refraction angles are then computed from the phase of the transformed wave field. The both groups of the methods are complementary to each other. Short term Fourier analysis is convenient for data visualization and identification of differen

Does a Priori Information Improve the Retrievals of Stellar Occultation Measurements?ments but continuous gas density profiles are wanted. Formally the problem can be transformed to a well-posed problem by simply discretizing the atmosphere into equally many layers as there are measurements and assuming, e.g., constant density inside each layer. We discuss here the advantages of req

GRAS-SAF Radio Occultation Data from EPS/Metopon and climate monitoring users. The GRAS SAF products promise globally distributed high-vertical resolution data on a 24 hour-basis, forming a considerable improvement on today’s measurement methods regarding coverage, vertical resolution, frequency, and cost. The accuracy requirements of the produ

Advancement of GNSS Radio Occultation Retrieval in the Upper Stratospherend bias reduction. It proved to be effective applied to a large sample of simulated occultation events especially in the formerly most critical regions. The results show that near bias-free global climatologies (temperature biases <0.5 K between 8 and 35–40 km) based on RO-measurements are feasible.

Ensemble-Based Analysis of Errors in Atmospheric Profiles Retrieved from GNSS Occultation Datalian refractivity retrieval and, subsequently, by dry air retrieval in the stratosphere and optimal estimation retrieval in the troposphere. The retrieved profiles were referenced to the “true” co-located ones of the ECMWF analysis field used as atmospheric model. Based on these data, we empirically
