This meeting is a follow-on to the 2025 summer workshop and will focus on the role of land–atmosphere interactions in predictability at subseasonal-to-seasonal (S2S) timescales (here defined as two weeks to three months). Building on last year’s outcomes, the workshop will bring together researchers, modelers and practitioners working on:
- Process-oriented metrics for evaluating land–atmosphere interactions in S2S models
- Application-oriented metrics to assess user-relevant aspects of S2S prediction
- Experimental protocols for coordinated S2S land–atmosphere experiments
- Demonstrations and early results applying these metrics and protocols in S2S modeling systems
- Community regionally refined simulations
- Applications of S2S forecasts to agriculture, water resources, wildfire, heatwave, extreme rainfall, and more
The program will include a mix of science and applications talks, working-group showcases, discussion of coordinated experiments, and planning for future community efforts.

Unifying Innovations in Forecasting Capabilities Workshop 2026 (UIFCW26) is an opportunity for community partners, across academia, industry, and government, to collaborate in the shared mission to advance forecasting capabilities. The theme for this year’s workshop is a New Frontier: Optimizing New Technology in a Changing Weather Enterprise. Objective of this workshop is to strengthen the understanding of the collaborative efforts to improve the Unified Forecast System (UFS), accelerate meaningful contributions, and measure progress more effectively.
Focus will continue on integrating sectors of the Weather Enterprise and fostering a community aligned with the mission of the Earth Prediction Innovation Center (EPIC), emphasizing government research and the crucial role of community building. UIFCW26 is dedicated to engaging and uniting efforts to advance forecasting capabilities for a more informed future.

The central question that governs the GEWEX Data and Analysis Panel (GDAP) mission is: “how sensitive is the Earth system to changes in radiative and other forcings?” Answering this question will enable improved prediction of transient natural variations, such as El Niño, and provide better understanding of the consequences of natural and human-induced Earth system changes.
The annual GDAP Meeting (by invitation only) is organized to bring together theoretical and experimental insights into the radiative interactions and Earth system feedbacks associated with cloud processes. During this meeting, participants, including panel members and invited local speakers, will evaluate the progress of the ongoing GDAP evaluations and projects and engage in discussions regarding potential collaboration and explore new project opportunities.
Central Asia as a region is extremely vulnerable to Earth system change. The majority of its water resources are from summer melting of the regions’ mountain glaciers and annual snowpack. In a warming world, glacial extent and volume, as well as the snowpack, are declining.
Initial steps for the proposed Regional Hydroclimate Project (RHP) in Central Asia have been to identify the relevant scientific and socio-economic community, its interests, priorities, and current capabilities and capacities. For more information about the Central Asia initiative visit https://www.gewex.org/central-asia-initiative/.

The 9th GEWEX Water Vapor Assessment (G-VAP) Workshop is hosted by the Danish Meteorological Institute (DMI) in Copenhagen, Denmark and will take place from 22-23 April 2026.
The main objectives of the G-VAP are:
- Quantifying the state of the art in water vapour products being constructed for climate applications, and, by this
- Supporting GEWEX Data and Analysis Panel ‘s (GDAP’s) selection process of water vapor products for its generation of globally consistent water and energy cycle products.
All three GCOS Essential Climate Variables on water vapor are considered.
It has been a while since the G-VAP community last met. Thus, a key objective is to finally meet again and catch up. Else, the objectives of the 9th G-VAP workshop are to:
- Discuss latest results from analysis of atmospheric water vapour and its role in the climate system
- Finalize the World Climate Research Program (WCRP) report on G-VAP results
- Discuss and plan the future of G-VAP
- Liaise with related initiatives and projects

2026 Pan-GLASS Conference
Back to the Drawing Board: From Fundamentals to Improved Models of the Coupled Land-Atmosphere System
The GEWEX Global Land-Atmosphere System Studies Panel (GLASS) will hold its first Pan-GLASS Conference “Back to the Drawing Board: From Fundamentals to Improved Models of the Coupled Land-Atmosphere System” (Pan-GLASS 2026). This conference is organized and performed by the Institute of Physics and Meteorology of the University of Hohenheim in Stuttgart, Germany, and the GLASS Panel with support of the International GEWEX Project Office of the World Climate Research Program (WCRP) and will take place in Stuttgart from 06-09 July 2026.
Pan-GLASS 2026 will bring together experts on earth system, weather, and climate research, soil and vegetation processes, surface fluxes, planetary boundary layer transport processes, clouds and precipitation, and machine learning. At the conference, observationalists, theoreticians, and modelers will join to discuss the key issues of land-atmosphere science. The program will include all aspects and methods of modeling and observing land-atmosphere interactions across different temporal-spatial scales: e.g., from diurnal to decadal; from ground-based measurements to satellite data; from large-eddy simulations to global earth system models. The topical areas will cover a wide spectrum from process understanding to parametrization development such as surface fluxes and their driving variables, the effects of land surface heterogeneity, evapotranspiration and entrainment, cloud and precipitation feedbacks; advanced observations including data processing and quality control; and idealized modeling to operational forecasting from subseasonal to seasonal, and prediction from seasonal to decadal and century and even longer timescales. The key objectives of this conference are to connect the land-atmosphere interactions community as well as to achieve progress in the understanding and modeling of the land-atmosphere system, to coordinate current international initiatives and make plans for the future.

Session of interest to the GEWEX Community:
Measurement and Modeling of Soil Processes Across Scales Co-organized by GI5/HS13 Convener: Mahyar NaseriECS Co-conveners: Nima Shokri, Lutz Weihermueller, Yan Jin
This session focuses on the measurement and modeling of soil properties and processes across landscapes, from the pore scale to the field or watershed scale. Organized in collaboration with the International Soil Modeling Consortium (ISMC), the session invites contributions that:
- Measure soil physical and chemical properties in the lab, field, or watershed using tools such as micro-scale imaging, in-situ soil sensors, drones, geophysical methods, radars, and remote sensing platforms.
- Model soil processes using analytical, empirical, statistical, or numerical approaches that link processes across scales, including upscaling and downscaling strategies to address heterogeneity in infiltration, evaporation, salinity dynamics, gas transport, and subsurface mass and energy fluxes.
- Investigate spatiotemporal changes in vadose zone properties at different scales through measurement or modeling campaigns, focusing on natural variability or human-driven changes such as climate variability, sea level rise and salinity intrusion, droughts, freeze-thaw cycles, heavy agricultural machinery impacts, and land management practices in forests, agricultural fields, wetlands, coastal zones, grasslands, deserts, urban soils, and mountainous regions.
Impact of Extreme Events on Biosphere-Atmosphere Exchanges Conveners: Pramit Kumar, Inke Forbrich, Rahul Kashyap, Kazuhito Ichii
This session invites submissions addressing the different aspects of the influence of extreme events on the ecosystem-atmosphere exchanges of gases and energy across scales. Encouraged are long-term measurements to identify such episodes of ‘disturbance’ and examine their impacts on the biosphere-atmosphere exchanges. In addition, submissions are encouraged that leverage in-situ or remotely sensed observations, and ecosystem or Earth system models to identify, measure, and simulate suc
The topic of the next session of the Explaining and Predicting Earth System Change (EPESC) Webinar Series is Characterising observational uncertainties.
