Dear all, The “3rd GNSS Polarimetric Radio Occultations Workshop” will take place 10-12 November 2025, at the EUMETSAT headquarters in Darmstadt, Germany. Registration is now available at the workshop main page<https:/www.eventsforce.net/gnsspro2025>: https://www.eventsforce.net/gnsspro2025<https:/www.eventsforce.net/gnsspro2025> This third workshop follows on to the “2nd GNSS Polarimetric Radio Occultation workshop<https:/doi.org/10.1175/BAMS-D-24-0050.1>” from 2023. It represents a forum for addressing multiple uses and applications that have been studied in the seven years that polarimetric RO (PRO) data have been available, align the presentation of these results, and prepare recommendations for meteorological, space and research organizations (e.g., CGMS agencies, the EUMETSAT ROM SAF) and satellite data providers. The workshop will feature presentations and discussions in the following areas: * Status of current and future polarimetric-capable RO observations * Precipitation, convection, extreme precipitation events * Use of PRO to evaluate model microphysical parameterization schemes * NWP and climate model evaluation * Assimilation of PRO observations * Simulations and comparisons between PRO and passive MW radiances * Recommendations to space agencies and data providers * ROM SAF consultation process While the workshop will offer a hybrid attendance format, in-person attendance is encouraged. If you would like to present materials at the workshop, you can enter (even a tentative) title at the time of registration. An abstract is not required. Further information and an agenda will be provided after registration closes.
