Dates: 22–23 April 2026 Location: Copenhagen, Denmark Extended Abstract Submission Deadline: 25 March 2026 Extended Registration Deadline: 10 April 2026 Assessments of data records related to
the global energy and water cycles are an integral part of GEWEX activities over the last few decades. The GEWEX Water Vapor Assessment (G-VAP) attempts to quantify the state-of-the-art in water vapor products designed for climate applications and support the GEWEX Data and Analysis Panel (GDAP)'s process for selecting water vapor products. One of the main objectives of the 9th G-VAP Workshop is to provide an opportunity for the community to meet after some time apart.
Other goals include: - Discussing the latest results from analysis of atmospheric water vapor and its role in the climate system
- Finalizing the World Climate Research Program (WCRP) report on G-VAP results
- Discussing and planning the future of G-VAP
- Liaising with related initiatives and projects
In order to participate in the
9th G-VAP workshop, please register at the latest by the extended deadline of 10 April 2026. |

Dates: 1–5 June 2026
Location: Pasadena, CA, USA, and online
The approach adopted in the GEWEX-Earth Energy Imbalance (EEI) assessment is to design an intercomparison of EEI estimates and associated uncertainty. Main goals for this workshop: - Assess closure of
Earth’s energy budget from the top of the atmosphere to the bottom of the ocean.
- Advance our understanding of the causes of ocean heat content and energy balance variations.
- Explain the spread across EEI estimates; derive and recommend methods that reduce and quantify EEI uncertainty.
- Identify gaps, challenges and opportunities for the EEI observing system of the future.

Dates: 22–26 June 2026 Location: Vienna, Austria Application Deadline: 1 May 2026 This summer school is devoted to runoff prediction in ungauged basins (PUB), i.e., predicting water runoff at locations where no runoff data are available. This lack of data presents considerable challenges to catchment
managers who require information on water flows for decision making. This course will provide hydrologists with the theory and methods to address this critical challenge. Masters and Ph.D. students researching catchment hydrology and practicing hydrologists who are challenged by making predictions in the absence of runoff data are invited to apply. |
