Dear Colleagues, We are pleased to announce the 7th International Conference on GPS Radio Occultation (ICGPSRO) 2025 website is now available: https://hmsstc.ncku.edu.tw/ICGPSRO/ <https://hmsstc.ncku.edu.tw/ICGPSRO/> The conference will be held on 28-30 October 2025 at the National Cheng Kung University, Tainan, Taiwan. The conference will address the scientific progresses of radio occultation missions and advanced GNSS technologies for the exploration of meteorology, climate, and space science. Tentative solicited topics are as follows. 1. Missions and programs (new missions and operations) 2. Retrieval methodology and science 3. Numerical weather prediction data assimilation advances and validation studies 4. Atmospheric physics and climate 5. Space weather 6. GNSS-Reflectometry 7. Innovative GNSS technologies Abstracts are now being accepted via the conference website, with a due date of September 24, 2025. Looking forward to seeing you in Tainan, Taiwan. Charles Lin and Jan-Peter Weiss on behalf of the organizing committee. 1. Vick Chu (Executive Vice Director of TASA) 2. Jan-Peter Weiss (UCAR COSMIC) 3.

Dear Colleagues, We are very pleased to let know you that the end-to-end (L0/L1A to L1B and LB to L2) daily STAR RO processed COSMIC-2 is online https://gpsmet.umd.edu/gnssro/download_star_nrt.php You may also download our near-real-time (as soon as the L0/L1A data are pushed to STAR) End-to-end processed Spire and PlanetiQ data under the same link. The reference for the L0/L1A processed package can be downloaded from https://www.mdpi.com/2072-4292/14/14/3288. The reference for the L1B to L2 processed package (using the STAR FSI RO processing algorithm) can be downloaded from https://www.mdpi.com/2072-4292/13/9/1793. Please email me (shu-peng.ho(a)noaa.gov) or the STAR data manager, Dr. Xi Shao (xi.shao(a)noaa.gov) if you have any questions. Please let us know how we can serve you better.

Reminder: registration open for 3rd GNSS Polarimetric Radio Occultations Workshop
by Hui Shao 03 Sep '25

03 Sep '25

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/eumetsat/frontend/reg/thome.csp?pageID=30083&ev…>. The deadlines are: - *15 October - Presentation submission deadline* - *25 October 2025 - Registration deadline* This third workshop follows on to the “2nd GNSS Polarimetric Radio Occultation workshop” 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. With kind regards, Christian Marquardt on behalf of Estel Cardellach (IEEC) and Joe Turk (JPL)
