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: Accelerating Improvements in the Modeling 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, 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.
Pan-GLASS 2026 will be primarily an in-person event with limited online participation options.
Program
The program consists of a combination of plenary and parallel sessions, with keynote and oral presentations. In addition, there is time reserved each day for poster presentations.
Call for Abstracts
Pan-GLASS 2026 will focus on the main themes mentioned below. For each of these themes, we are calling for studies relying on process-oriented diagnostics, modeling as well as new observational data and their synergy, applied to enhance our understanding and modeling capabilities of land-atmosphere interaction. The conference will revolve around the following core themes:
Proposals for potential new community projects are particularly welcomed, including proposing a topic and possible approaches OR proposing specific activities in greater detail.
Detailed information about the Call for Abstracts can be found in Themes and Sessions.
Pan-GLASS 2026 will organized two competitions for Early Career Researchers (ECRs). You are deemed an ECR if you are an undergraduate or postgraduate (Masters/PhD) student or a scientist who has received his or her highest degree (BSc, MSc, or PhD) within the past six years. If parental leave fell in this period, up to one year of parental leave time may be added per child, up to a maximum of four years.
