Linking Hydrology and Greenhouse Gases in Environmental Models

24-28 March 2025

Objective

The course’s objective is to understand how hydrology impacts biogeochemical processes in different ecosystems, and how these processes can be represented in environmental models at different scales.

Course description

The course will gather experts in modelling of different ecosystems (agricultural systems, wetlands, forests) and at different scales (site scale, catchment scale, global scale). With a combination of lectures, student presentations on students’ individual PhD projects, discussion groups, group exercises and plenary discussions, we will compare and contrast the different approaches and will obtain a broad understanding of how these interactions are represented in models, how these interactions can be scaled to large scales, and how these can be used in accounting of greenhouse gas balances.

Current positions available in the Global Wetland Center:

Postdoc in Modelling of Ecosystem Biogeochemistry of Wetlands

3-year full time postdoctoral position on the development and application of models, to simulate the ecosystem biogeochemistry of wetlands, at regional to global scales.

We are looking for a candidate that will develop and use modelling tools constrained by observations to simulate emissions of CO2, CH4 and N2O from wetlands. We envisage combining process-based modelling and machine learning, as well as integration of Earth observation data into the modelling framework. The objective is to quantify the GHG budgets of wetlands across the globe (tropical inland wetlands, northern high-latitude wetlands, coastal wetlands) under current and future climatic conditions and investigate direct anthropogenic impacts by quantifying the roles of wetland management (draining, rewetting) and land use.

Specifically, we hope to find a candidate who is eager to investigate new modelling techniques (e.g., differentiable programming) for upscaling of GHG fluxes, and who is willing to discuss the model complexity needed to capture global-scale wetland GHG emissions. The work will build on ongoing model development in the Global Wetland Center, and will require a close collaboration with hydrological modellers, experts in Earth observation, and computer scientists. 

Application deadline: 5 October 2026.
