Abstract

The assimilation of GPS radio occultations within the three-dimensional variational data assimilation system of the German Weather Service requires GPS radio occultation bending angle forward operators. To optimize the forward operator setup, different one- and three-dimensional bending angle forward operators are evaluated. The innovation statistics for radio occultation data from the CHAMP, GRACE-A and FORMOSAT-3/COSMIC satellites are compared with estimates based on the background and observation errors specified in the assimilation scheme. Numerical experiments are performed to assess the impact of assimilated radio occultation data on the weather forecast scores.
