Prithvi WxC: Foundation Model for Weather and Climate

2 code implementations20 Sep 2024 Johannes Schmude, Sujit Roy, Will Trojak, Johannes Jakubik, Daniel Salles Civitarese, Shraddha Singh, Julian Kuehnert, Kumar Ankur, Aman Gupta, Christopher E Phillips, Romeo Kienzler, Daniela Szwarcman, Vishal Gaur, Rajat Shinde, Rohit Lal, Arlindo Da Silva, Jorge Luis Guevara Diaz, Anne Jones, Simon Pfreundschuh, Amy Lin, Aditi Sheshadri, Udaysankar Nair, Valentine Anantharaj, Hendrik Hamann, Campbell Watson, Manil Maskey, Tsengdar J Lee, Juan Bernabe Moreno, Rahul Ramachandran

Triggered by the realization that AI emulators can rival the performance of traditional numerical weather prediction models running on HPC systems, there is now an increasing number of large AI models that address use cases such as forecasting, downscaling, or nowcasting.

Evaluating the transferability potential of deep learning models for climate downscaling

no code implementations17 Jul 2024 Ayush Prasad, Paula Harder, Qidong Yang, Prasanna Sattegeri, Daniela Szwarcman, Campbell Watson, David Rolnick

Climate downscaling, the process of generating high-resolution climate data from low-resolution simulations, is essential for understanding and adapting to climate change at regional and local scales.

Fine-tuning of Geospatial Foundation Models for Aboveground Biomass Estimation

no code implementations28 Jun 2024 Michal Muszynski, Levente Klein, Ademir Ferreira da Silva, Anjani Prasad Atluri, Carlos Gomes, Daniela Szwarcman, Gurkanwar Singh, Kewen Gu, Maciel Zortea, Naomi Simumba, Paolo Fraccaro, Shraddha Singh, Steve Meliksetian, Campbell Watson, Daiki Kimura, Harini Srinivasan

In this paper, we explore the effectiveness of fine-tuning of a geospatial foundation model to estimate above-ground biomass (AGB) using space-borne data collected across different eco-regions in Brazil.

Hard-Constrained Deep Learning for Climate Downscaling

1 code implementation8 Aug 2022 Paula Harder, Alex Hernandez-Garcia, Venkatesh Ramesh, Qidong Yang, Prasanna Sattigeri, Daniela Szwarcman, Campbell Watson, David Rolnick

In order to conserve physical quantities, here we introduce methods that guarantee statistical constraints are satisfied by a deep learning downscaling model, while also improving their performance according to traditional metrics.

Wildfire risk forecast: An optimizable fire danger index

no code implementations28 Mar 2022 Eduardo Rodrigues, Bianca Zadrozny, Campbell Watson

This approach has two benefits: (1) the NFDRS IC parameters can be improved for each region using actual observed fire events, and (2) the internal variables remain intact for interpretations by specialists instead of meaningless hidden layers as in traditional neural networks.

Controlling Weather Field Synthesis Using Variational Autoencoders

no code implementations30 Jul 2021 Dario Augusto Borges Oliveira, Jorge Guevara Diaz, Bianca Zadrozny, Campbell Watson

One of the consequences of climate change is anobserved increase in the frequency of extreme cli-mate events.

Extreme Precipitation Seasonal Forecast Using a Transformer Neural Network

no code implementations14 Jul 2021 Daniel Salles Civitarese, Daniela Szwarcman, Bianca Zadrozny, Campbell Watson

An impact of climate change is the increase in frequency and intensity of extreme precipitation events.

Decadal Forecasts with ResDMD: a Residual DMD Neural Network

no code implementations21 Jun 2021 Eduardo Rodrigues, Bianca Zadrozny, Campbell Watson, David Gold

Operational forecasting centers are investing in decadal (1-10 year) forecast systems to support long-term decision making for a more climate-resilient society.
