ORNL at AGU: Making climate models smarter


Lexie yang

Exploration of spatially distributed deep learning models for global gravitational mapping

New approaches developed by scientists, including ORNL’s Lexie Yang, analyze massive datasets of large-scale satellite images to more accurately map infrastructure – such as buildings and roads – in hours rather than in hours. days. Comprehensive image data is useful for stakeholders to make informed decisions. These new IT workflows use deep learning techniques to train and deploy models to better address location, environmental, and time challenges when mapping structures. Yang’s AGU presentation will focus on global gravity mapping.

Optimal resolution urban land entries for microclimate modeling for local climate decision support

The impacts of climate change differ in cities and in rural areas. Melissa Allen Dumas’ research focuses on the impact of weather and atmospheric conditions, people’s behavior and activities, and the presence of concrete and asphalt on urban neighborhoods. This information creates smarter climate models that could help neighborhoods adapt and develop better climate change mitigation strategies. Dumas will lead an AGU presentation of his team’s work.

Towards more mechanistic representations of biogeochemical processes in river networks: implementation and demonstration of a multiscale model

New information about what is happening in rivers – and the microbial areas adjacent to them – may provide a better understanding of how water quality will be affected by climate change, land use and population growth. Scott Painter and his colleagues at ORNL have developed a new modeling capability that integrates important biogeochemical processes in river systems, the subject of this AGU presentation.

Improving Earth System Predictability: New Mechanisms, Feedbacks, and Approaches to Predict Global Biogeochemical Cycles in Earth System Models

Earth system computer scientist Forrest Hoffman and his team make sophisticated climate models even smarter by “listening” to the Earth and determining how environmental cycles and interactions can impact the overall health of the Earth. His presentation at AGU will explain how this can be applied to better predict future levels of carbon dioxide in the atmosphere.

How can the choice of downscaling techniques and baseline meteorological observations affect future hydroclimatic projections?

Deeksha Rastogi, a computer scientist at Oak Ridge National Laboratory, partners with colleagues in high performance computing to understand the human impacts of climate change. It uses Earth system modeling and scientific data analysis to project how climate change is likely to affect electricity demand, hydroelectric power generation, critical infrastructure and human health. His presentation at the AGU will focus on techniques for improving these models, particularly in connection with future hydroclimatic projections.
