We are delighted to announce the VOCALIS Workshop (Validation of Operational Copernicus Altimetry over Land water and Ice Surface Workshop), taking place 21–25 September 2026 in Longyearbyen, Svalbard. Please mark these dates in your calendars.

This workshop will bring together experts from the CRISTAL IN-PROVA and ST3TART-FO ESA projects, alongside representatives from Copernicus services, Copernicus In-Situ, EEA, and MAG/QWG/S3VT. It will provide a unique forum to:

• Share and discuss project outcomes
• Exchange insights on operational validation of Sentinel-3 altimetry products
• Contribute to shaping future Cal/Val activities for the CRISTAL mission and beyond

Further details on logistics, registration, venue, programme, and abstract submission will follow shortly.

We look forward to welcoming you to Svalbard for what promises to be an engaging and productive event. Please feel free to share this announcement within your networks and with colleagues who may be interested!
