NVIDIA Climate and Weather Research

Welcome to the homepage of the NVIDIA Climate and Weather Simulation Research Lab, led by Mike Pritchard and founded in 2022. Our mission is to re-imagine technology across the Earth System Modeling stack using new ideas in AI on applied topics such as autoregressive Earth System prediction, hybrid physics-AI climate simulation, atmospheric state estimation, generative data assimilation, convection-permitting high-resolution simulation, steerable climate state sampling – and related frontiers.

Technology developed by our team is integrated into NVIDIA PhysicsNemo and Earth2Studio.

Research Areas

Weather

AI models can out-compete physics-based numerical models for weather prediction tasks. Accurately predicting the evolution of atmospheric state vectors, and evaluating skill based on appropriate probabilistic measures, are essential. Our lab has advanced AI forecasting techniques such as FourCastNet, StormCast and DLESyM and developed associated libraries such as e2grid and CuHPX. Major challenges ahead include scaling to increasingly expressive architectures, multi-modal observational datasets, multi-component Earth System prediction, multi-month prediction time horizons, and advancing the frontier of convective-permitting AI weather prediction for storm-scale dynamics.

Climate

Predicting climate with AI is harder than predicting the weather. Our lab has advanced methods for hybrid physics-AI climate prediction (ClimSim) and autoregressive atmosphere- and ocean-coupled climate prediction (OLA, DLESyM, ACE). Open challenges include controlling drift and stability and evolving multi-component autoregressive AI Earth System models to become fully featured for operational climate prediction under scenarios of changing greenhouse gases, land surface state, aerosols, including associated physical feedbacks from clouds and ecosystems, alongside estimates of their uncertainty.

Control

For informatics use cases, AI samplers provide a way to sidestep challenges of autoregressive prediction by explicitly conditioning future weather samples on climate-controlling factors using generative AI. Climate in a Bottle is a research prototype that demonstrates this alongside 13M-pixel super-resolution at the scale of next-generation global cloud resolving climate modeling complexity. Open challenges include generalizing user-control during sampling and avoiding overfitting to sufficiently learn subtle climate change trends hiding amidst strong internal variability especially when training data are limited in duration but high resolution in space and time.

Downscaling

World governments have produced many coarse-resolution projections of future climate. Super-resolving, i.e. downscaling, these data becomes useful for impacts-relevant planning. Our lab has contributed to AI methods like CorrDiff for multivariate generative super-resolution and new channel synthesis. Key challenges include the high dynamic range and low inter-channel correlations of climate data compared to imagery.
