International Mountain Conference
Dates: 14–18 September 2025
Location: Innsbruck, Austria
The International Mountain Conference (#IMC) builds upon the previous mountain conferences and aims to continue this scientific conference series exclusively targeted towards mountain research. The key goals of the conference are to synthesize and enhance our understanding of mountain systems, in particular their response and resilience to global change. Two GEWEX-related sessions are listed below.
FS 3.316: Precipitation Changes in Mountainous Hydroclimates
Conveners: Michael Brody, Lucia Scaff, Paolo Arias, John Pomeroy, Ali Behrangi
In this session, the conveners plan to explore the research on mountain precipitation, how it changes in a changing climate, and how to tackle the observation-modeling mismatch. Papers are invited that discuss the various observation strategies of precipitation in mountainous regions, novel methods of observation including those that use AI/ML, Earth observation/remote sensing and/or citizen science. Papers are also invited that discuss model advances and evaluate modeling and reanalysis products against in-situ and remote sensing observations in mountainous regions to address the lack of observations.
FS 3.116: High mountain hydrology and cryosphere under global change: observations, modelling, prospects
Conveners: Chris DeBeer, John Pomeroy, Ignacio López Moreno, James McPhee
There is a global need to better understand high mountain atmospheric, hydrological and cryospheric processes, improve their prediction as coupled systems, and diagnose their sensitivities to global change to promote water sustainability. This session welcomes contributions addressing any of the critical research questions, and particularly welcomes contributions on observations from instrumented mountain catchments, theoretical advances and on evaluation of hydrological and atmospheric models using observations to better understand model performance and to see if models reproduce known aspects and regimes of the coupled atmospheric-cryospheric-hydrological system.
AOGS2025
Dates: 27 July–1 August 2025
Location: Singapore
The next Asia Oceania Geosciences Society 2025 (AOGS2025) is set to take place in Singapore from 27 July to 1 August 2025. The eight geoscience disciplines of the society—Atmospheric (AS), Biogeoscience (BG), Hydrological (HS) Interdisciplinary (IG), Ocean (OS), Planetary (PS), Solar & Terrestrial (ST), and Solid Earth (SE)—are the focus of the annual meeting, which is open to scientists, researchers, and practitioners in these fields. GEWEX is helping to convene the following session:
Session Title: The Third Pole Environment and High Mountains of Central Asia – Hydrometeorological Processes and Human Dimension
AS – Atmospheric Sciences
Conveners: Dr. Petrus (Peter) van Oevelen (George Mason University), Prof. Li Jia (Chinese Academy of Sciences), Dr. Xin Li (Chinese Academy of Sciences), Prof. Yaoming Ma (Chinese Academy of Sciences), Dr. Toru Terao (Kagawa University)
Busan IAMAS-IACS-IAPSO Joint Assembly 2025 (BACO-25)
Dates: 20–25 July 2025
Location: Busan, Republic of Korea
BACO-25 will take place over six days in July, when colleagues from academia, government, and industry worldwide will engage in scientific presentations, discussions, information exchanges, and international cooperation in the Earth sciences. A session of interest to the GEWEX community is listed below.
Session title: JCM02 Cryosphere changes and potential drivers in High Mountain Asia
Conveners: Mohd. Farooq Azam, Lijuan Ma, Raaj Ramsankaran, and Peter J. van Oevelen
Description: Understanding the response of the High Mountain Asia (HMA) cryosphere to climate change is crucial for millions of people living downstream who partly depend on meltwater. Changes in snow cover and permafrost still need to be better understood. Contributions based on remote sensing, in-situ observations, or numerical modeling of cryosphere changes in the HMA are invited. The conveners especially encourage studies integrating atmospheric and cryospheric interactions with remote sensing data and exploring the potential drivers behind observed changes.
The Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment (LIAISE) project, part of the international HyMeX initiative, focuses on enhancing our understanding of land-atmosphere-hydrology interactions in Spain’s semi-arid Ebro basin, a region characterized by its significant agricultural activities and contrasting natural dry zones.
This conference aims to unite researchers specializing in estimating the various components of the surface water and energy cycles experimentally using in-situ observations, via remote sensing data and/or models, from the leaf to the regional scale. The emphasis will be on semi-arid bread-basket regions.

Join the Planetary Boundary Layer (PBL) community to continue charting a path forward in preparation for the next Decadal Survey and beyond at the Decadal Survey Incubation (DSI) PBL Community Meeting. The meeting, which will be held April 1-3, 2025 in Silver Spring, MD, USA, is open to all interested in PBL science and the technologies to enable those measurements.
A draft meeting agenda is available at https://meeting-info.org/pbl/, along with links for meeting registration and hotel reservations. All in-person attendees are invited to present posters. Community members attending in person are invited to request time for an oral presentation during registration. Note that time slots are limited, so some submissions may be accepted as posters. The deadline to register and request posters and community presentations is February 28!
Additional information about the DIS-PBL program, including the recent PBL study report, can be found at https://science.nasa.gov/earth-science/decadal-pbl.
The 2025 Gordon Research Conference (GRC) on Radiation and Climate will focus on key uncertainties in radiation and climate science with particular emphasis on novel approaches to bridge observations and modelling across scales to advance our physical understanding and predictive capabilities. This is timely, with global Earth observations and high-resolution models approaching process scales. The program will capitalize on novel Earth observations as well as the transformation of global climate modelling through computational advances and AI.
This GRC will be held in conjunction with the “Radiation and Climate” Gordon Research Seminar (GRS).

The crossroads of observations and modelling motivate the theme of the Gordon Research Seminar (GRS) this year: advancing physical understanding of radiation and climate through observations, models, and other methodologies at the nexus of these approaches.
The Radiation and Climate GRS provides a unique forum for young doctoral and post-doctoral researchers to present their work, discuss new methods, cutting edge ideas, and pre-published data, as well as to build collaborative relationships with their peers. Experienced mentors and trainee moderators will facilitate active participation in scientific discussion to allow all attendees to be engaged participants rather than spectators.
This GRC will be held in conjunction with the “Radiation and Climate” Gordon Research Conference (GRC).

Students will be introduced into fundamental processes of the atmosphere, ocean, sea-ice and land surface with relevance for the climate system. The course will deal with coupled atmosphere-ocean climate models, climate change, the greenhouse gas effect and other drivers of regional climate, dynamical downscaling, and the variability of circulation and regional climate. In additon, the possible impact of climate change on the marine ecosystem including biogeochemical cycles will also be studied.
With the help of teachers from several disciplines, a holistic Earth System approach will be presented although the main focus of the course is on the physical aspects of changing climate. In addition to lectures, tutorials, exercises and literature studies the course will give the students the opportunity to discuss the learned topics further during group exercises.
