Machine Learning Enhancements to NASA Weather and Climate Modeling

Our Planet
Simulation modeling global aerosols from March 1, 2007 to June 16, 2007.
This Goddard Earth Observing System (GEOS) model global aerosols simulation spans March 1, 2007–June 16, 2007. These aerosols — particles suspended in Earth’s atmosphere — can be emitted from natural sources like sea salt and pollen or from anthropogenic sources such as combustion and land use change. Aerosols influence Earth’s atmospheric composition, can absorb or reflect incoming solar radiation, and serve as the building blocks for cloud formation. NASA uses constrained simulations of aerosols as a crucial component of predicting atmospheric chemistry and physics related to climate change. Researchers are making machine learning enhancements to GEOS focused on representation of cloud formation and atmospheric composition. William Putman, NASA/Goddard

Numerical computations and simulations representing many complex and interrelated physical processes are significant drivers of modern scientific progress. In recent years, machine learning (ML) applications in weather and climate simulation and prediction have promised to accelerate the accuracy and computational processing power of Earth System Models (ESMs). NASA is applying ML applications agency-wide for projects supporting mission objectives. Efforts include building foundation models for weather and climate; developing radiative-transfer emulators; and studying planetary science and exploration, biogeochemical processes and oceanography, hydrology, and atmospheric science. A major focus at NASA Goddard Space Flight Center has been making a variety of ML enhancements to NASA’s Goddard Earth Observing System (GEOS) atmospheric model — a weather and climate ESM developed for analyses and weather forecasts of Earth’s atmosphere, climate simulations and predictions, and chemistry-resolving simulations.

NASA's high-performance computing resources have enabled the development of ML models that enhance the representation of cloud formation and atmospheric composition. By analyzing extensive observational and high-resolution simulation data, these models improve predictions of atmospheric chemistry and physics, as well as the associated impacts on effective radiative forcings, which are crucial for understanding and addressing climate change.
