The AGU Annual Meeting 2025 will take place 15–19 December in New Orleans, Louisiana, bringing together researchers from around the world to share advances across the Earth and space sciences. For LEMONTREE, AGU is a particularly important meeting: with four U.S. university partners—Berkeley, Columbia, Texas Tech and the University of Pittsburgh—this conference is always a natural home for our science. We have regularly featured at AGU in previous years (see our 2022 and 2024 highlights) and are delighted to continue this tradition in 2025.
This year, thirteen members of the LEMONTREE community will represent the project, spanning institutions across the U.S. and also Seoul National University and Tsinghua University. Their contributions reflect the breadth and ambition of LEMONTREE’s research, from plant functional ecology and ecohydrology to land–atmosphere interactions, carbon cycle science, and next-generation modelling frameworks.
Invited Talks
We are proud to have three invited talks this year:
- Professor Youngryel Ryu (Seoul National University) will present new insights from long-term satellite observations revealing sustained global greening and improved understanding of tropical seasonality.
- Professor Pierre Gentine (Columbia University) will give two invited contributions, including work on global model data fusion to unravel land carbon sinks and an exploration of parsimony versus complexity in Earth system modelling.
These invited talks recognise the influential role LEMONTREE researchers play in advancing theory, modelling and global-scale data integration.
It’s going to be a busy week for the team. Here’s our line up and you can click on the links for the abstracts and room details:
