Short Abstract: In European forests that are divided into stands of small size and may show heterogeneity within stands, a high spatial resolution (10 – 20 meters) is arguably needed to capture the differences in canopy height. In this work, we developed a deep learning U-Net model based on multi-stream remote sensing measurements to create a high-resolution canopy height map of France. Our model uses multi-band images from Sentinel-1 and Sentinel-2 with composite time averages as input to predict tree height derived from GEDI waveforms. Thanks to forest inventory plots, we then turned this height map into a 10 m resolution wood volume map that we used to carry out wood volume estimations in different french regions. This works paves the way to a monitoring of biomass at high resolution and could bring key information for forest management policies.

BioMartin Schwartz is a young researcher who graduated from Ecole Polytechnique in 2020. During his gap year, he worked at Carbone 4, a leading consulting firm specializing in climate change and sustainability. Currently, Martin is in his 3rd year of PhD, supervised by Philippe Ciais and Catherine Ottlé at the Laboratory for Climate Science and Environment (LSCE). His research is focused on remote sensing and deep learning techniques applied to GEDI data, with the aim of advancing our understanding of forest canopy height and forest biomass at fine scale. His work has been done in collaboration with Kayrros which helped in the development of his research.

Kayrros: Kayrros is a French company that leverages advanced technologies like AI and satellite imagery to provide real-time insights and forecasting for the energy and commodity markets, with a focus on sustainability and environmental issues.

AI4Climate seminar: Machine Learning for Climate Change and Environmental Sustainability – Claire Monteleoni – 6th of February 11:00CET

The seminar is on February the 6th, at 11:00 (CET) remotely and in person. The in-person meeting will be held in the SCAI conference room (map at the end of the post).

Despite the scientific consensus on climate change, drastic uncertainties remain. Crucial questions about regional climate trends, changes in extreme events, such as heat waves and mega-storms, and understanding how climate varied in the distant past, must be answered in order to improve predictions, assess impacts and vulnerability, and inform mitigation and sustainable adaptation strategies. Machine learning can help answer such questions and shed light on climate change. I will give an overview of our climate informatics research, focusing on challenges in learning from spatiotemporal data, along with semi- and unsupervised deep learning approaches to studying rare and extreme events, and precipitation and temperature downscaling.

Claire Monteleoni is a Choose France Chair in AI and Directrice de Recherche at INRIA Paris, an Associate Professor in the Department of Computer Science at the University of Colorado Boulder, and the founding Editor in Chief of Environmental Data Science, a Cambridge University Press journal, launched in December 2020. She joined INRIA in 2023 and has previously held positions at University of Paris-Saclay, CNRS, George Washington University, and Columbia University. She completed her PhD and Masters in Computer Science at MIT and was a postdoc at UC San Diego. She holds a Bachelor’s in Earth and Planetary Sciences from Harvard. Her research on machine learning for the study of climate change helped launch the interdisciplinary field of Climate Informatics. She co-founded the International Conference on Climate Informatics, which turns 12 years old in 2023, and has attracted climate scientists and data scientists from over 20 countries and 30 U.S. states. She gave an invited tutorial: Climate Change: Challenges for Machine Learning, at NeurIPS 2014. She currently serves on the NSF Advisory Committee for Environmental Research and Education.

Journal Club of V. Balaji

We are hereby re-transmiting the Journal Club news:

This is an announcement of a ‘Journal Club’ on the subject of ‘machine learning’ (ML) methods and their potential application in Earth System modeling (ESM). We will read together (with some imagination the name of the journal club can be pronounced ‘ensemble’!) some of the key papers in this nascent domain, to give ourselves ideas and inspiration on how to integrate these methods in our work, to find a common language between the ESM and ML disciplines, between theory and practice, between idealized systems and the Earth system.
The rules of the game are: someone picks an article where she would like to lead a discussion. To be clear, ‘leading’ doesn’t mean explaining the whole paper: everyone is supposed to have read the paper beforehand, and the discussion will cover points in the paper that aren’t clear, potential flaws and holes, and ideas on how to continue down the path ourselves.
I will lead the first one-hour session, and hope that others will volunteer to lead future ones! It will be on a monthly schedule, every third Thursday, at 14h.
Thus the first is scheduled for 21 February 2019.  There is a room reserved at Jussieu at METIS (Campus Pierre et Marie Curie – Salle Henry Darcy – 3e étage – couloir 46-56) and a visio as well to allow participation from Paris and Saclay campuses. Details, see below.
We will begin with these two articles:
– Schneider et al 2017: Earth System Modeling 2.0: A Blueprint for Models That Learn From Observations and Targeted High‐Resolution Simulations.
– Bolton and Zanna 2019: Applications of Deep Learning to Ocean Data Inference and Subgrid Parameterization.

Hope to see you on the 21st. To have some idea of the level of interest, please drop me a note… but please don’t ‘reply all’ !

Thiria (Sorbonne Univ., IPSL). 

L’objectif de cette journée est de réunir les acteurs qui s’intéressent à l’interface entre les modèles et technologies de l’intelligence artificielle, notamment de l’apprentissage, et les sciences de l’atmosphère, de l’océan et du climat. Nous souhaitons à la fois présenter et discuter le potentiel et les avancées récentes de l’IA pour les domaines Océan-Atmosphère-Climat et échanger sur les actions pertinentes pour animer, soutenir et structurer ces activités à l’échelle nationale.

Le programme de cette journée comprendra :

– des exposés invités par S. Brunton (Prof. Univ. of Washington) et V. Balaji (Prof., Princeton Univ.)

– des exposés oraux (20’ à 25’) de contributions soumises à cet appel (cf. ci-dessous)
