The GEWEX Data and Analysis Panel (GDAP) was organized to bring together theoretical and experimental insights into the radiative interactions and climate feedbacks associated with cloud processes. The central question that governs the GDAP mission is: “how sensitive is the Earth’s climate to changes in radiative and other forcings?” Answering this question will enable improved prediction of transient natural climate variations, such as El Niño, and provide better understanding of the consequences of natural and human-induced climate changes.
During 2025 GDAP meeting, participants will evaluate the progress of current GDAP assessments and projects. They will also engage in discussions regarding potential collaboration and explore new project opportunities. As one of the four panels of the Global Energy and Water Cycle Exchanges (GEWEX), a core program of the World Climate Research Program (WCRP), the GEWEX Science Questions and the WCRP Lighthouse activities will be at the heart of these discussions.
The 2025 GDAP meeting is planned to take place in conjunction with the Upper-Tropospheric Clouds and Convection (UTCC) Process Evaluation Study (PROES) meeting.
Participation is for Panel members and invited guests only.

The Baltic Earth Working Group on “Multiple drivers for Earth system changes in the Baltic Sea” has intended to provide an overview over the different human drivers and interrelations between them in the Baltic Sea region. The first Baltic Earth Workshop on this topic in Tallinn in 2018 set the stage and established a group of interested scientists which culminated in a writing team for the comprehensive Baltic Earth Assessment Report (BEAR) paper in Earth System Dynamics: “Human impacts and their interactions in the Baltic Sea region.”
After the completion of the first phase of Baltic Earth and with the onset of a new phase, the Baltic Earth Working Group on “Multiple drivers for Earth system changes in the Baltic Sea” will be revisited. This international Workshop shall set the scope for the new phase of this updated Baltic Earth Research Topic (RT) and bring together scientists and managers who are interested in collaborating in this continued Baltic Earth activity.

Baltic Earth and its predecessor BALTEX have been part of the global GEWEX family since 1992. Ali Nazemi of Concordia University, Montreal, Canada, is chairman of the GEWEX Hydroclimatology Panel and provides an overview over the various activities and benefits of this worldwide research programme.
The Global Energy and Water Cycle Exchanges (GEWEX) was created more than 30 years ago within the framework of the World Climate Research Programme (WCRP). To date GEWEX has remained as a vibrant core project within the WCRP, aiming at addressing science gaps in the understanding of Earth’s energy and water cycles given a lack of information about the basic fluxes and associated reservoirs of these cycles. GEWEX activities are pursued within four panels, one of which being GEWEX Hydroclimatology Panel (GHP) that aims to understand and predict continental to local-scale hydroclimates for hydrologic applications. GHP itself consists of four categories of activities, including Regional Hydroclimatic Projects (RHPs), under which Baltic Earth is a flagship program, Crosscutting projects (CCs), Data Centers (DCs) and GHP Networks (GNs). Each of these activities play a unique and vital role in chasing GHP ambitions. This talk focuses on introducing current activities under these types of activities and demonstrates how, together and on their own, they can improve our understanding of various hydroclimatic processes and our ability to predict them across scales. The talk highlights the importance of a wider engagement between different communities and the necessity of international collaboration for making progress on understanding and on the monitoring of the changes in the energy and water cycles under ever increasing human pressures. A vision of the path forward for the coming decade, including the goals of GHP for the future, are also described.

Future predictions of the Earth system are uncertain, whether spanning a few days or many decades. A key source of uncertainty across all these timescales are the approximations made when building the Earth System Model used to make the prediction. This is called model uncertainty.
This workshop will bring together different communities interested in model uncertainty, including, but not limited to: those working on weather prediction through climate timescales; those focused on physical parametrizations, the dynamical core, or their coupling and interaction; those using high-resolution km-scale models through complex Earth System Models; whether limited area or global.
The workshop will include invited talks, contributed talks, and posters. We will hold breakout groups to foster deeper discussion on the key workshop themes. We plan for the workshop to be partially hybrid – while all presentations will be in person, we will livestream talks and facilitate online Q&A. For more details on how you can participate, please see the ‘Registration’ page.
