Get Your Embedding Space in Order: Domain-Adaptive Regression for Forest Monitoring

no code implementations1 May 2024 Sizhuo Li, Dimitri Gominski, Martin Brandt, Xiaoye Tong, Philippe Ciais

Image-level regression is an important task in Earth observation, where visual domain and label shifts are a core challenge hampering generalization.

SolarEV City Concept for Paris: A promising idea?

no code implementations31 May 2023 Paul Deroubaix, Takuro Kobashi, Léna Gurriaran, Fouzi Benkhelifa, Philippe Ciais, Katsumasa Tanaka

Furthermore, the systems potentially allow rapid CO2 emissions reduction; however, with already low-carbon electricity of France by nuclear power, CO2 abatement (0. 020 kgCO2kWh-1 reduction from 0. 063 kgCO2kWh-1) by PV + EV system can be limited, in comparison to that (0. 270 kgCO2kWh-1 reduction from 0. 352 kgCO2kWh-1) of Kyoto, also because of the Paris low insolation and high demands in higher latitude winter.

High-resolution canopy height map in the Landes forest (France) based on GEDI, Sentinel-1, and Sentinel-2 data with a deep learning approach

no code implementations20 Dec 2022 Martin Schwartz, Philippe Ciais, Catherine Ottlé, Aurelien De Truchis, Cedric Vega, Ibrahim Fayad, Martin Brandt, Rasmus Fensholt, Nicolas Baghdadi, François Morneau, David Morin, Dominique Guyon, Sylvia Dayau, Jean-Pierre Wigneron

In intensively managed forests in Europe, where forests 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.

Paris Agreement requires substantial, broad, and sustained engagements beyond COVID-19 public stimulus packages

no code implementations16 Apr 2021 Katsumasa Tanaka, Christian Azar, Olivier Boucher, Philippe Ciais, Yann Gaucher, Daniel J. A. Johansson

It has been claimed that COVID-19 public stimulus packages could be sufficient to meet the short-term energy investment needs to leverage a shift toward a pathway consistent with the 1. 5 degrees C target of the Paris Agreement.

Global Daily CO$_2$ emissions for the year 2020

no code implementations3 Mar 2021 Zhu Liu, Zhu Deng, Philippe Ciais, Jianguang Tan, Biqing Zhu, Steven J. Davis, Robbie Andrew, Olivier Boucher, Simon Ben Arous, Pep Canadel, Xinyu Dou, Pierre Friedlingstein, Pierre Gentine, Rui Guo, Chaopeng Hong, Robert B. Jackson, Daniel M. Kammen, Piyu Ke, Corinne Le Quere, Crippa Monica, Greet Janssens-Maenhout, Glen Peters, Katsumasa Tanaka, Yilong Wang, Bo Zheng, Haiwang Zhong, Taochun Sun, Hans Joachim Schellnhuber

That even substantial world-wide lockdowns of activity led to a one-time decline in global CO$_2$ emissions of only 5. 4% in one year highlights the significant challenges for climate change mitigation that we face in the post-COVID era.
