The algorithms for ROHP-PAZ data inversion are ready

A probabilistic inversion technique has been developed for GNSS polarimetric radio occultation (GNSS-PRO) observables. It results in a series of probabilities of rain rates, at different altitudes. These vertical profiles of rain probability complement the standard GNSS-RO thermodynamic profiles, providing a unique insight within intense precipitation scenarios. This new measurement concept will be tested in the Radio-Occultation and Heavy Precipitation experiment aboard PAZ (ROHP-PAZ), to be launched in January 2018.

The statistical algorithms to retrieve rain rate information from the polarimetric Radio-Occultations have been developed, tested with synthetic data and they are now published at the 'Quarterly Journal of the Royal Meteorological Society' (QJRMS).
