Running Pretrainined AI-NWP Models, Our Experience at NSF Unidata on Jetstream2

07 May 2025

At NSF Unidata, we have successfully implemented and re-used weights from several global AI-NWP (Artificial Intelligence-Numerical Weather Prediction) models (FourCastNet, Pangu) using the NVIDIA earth2mip package. We can confirm that these models are open source and can be reused on high-end, but increasingly standard, HPC hardware. While traditional numerical weather prediction requires massive supercomputing resources, these AI models can potentially deliver similar or better results using standard GPU hardware for inference.

Book Review - StatQuest Guide to Neural Networks

10 February 2025

The StatQuest Illustrated Guide to Neural Networks and AI: With hands-on examples in PyTorch!!! strikes an excellent balance between accessibility and technical depth. Josh Starmer, PhD, builds on his previous work while making neural networks approachable for both students and practitioners. This book has a similar feel and vibe to the previous book, The StatQuest guide to Machine Learning.

Reflections on the 2024 Emerging Pedagogies Summit

24 October 2024

The Emerging Pedagogies Summit is an annual event hosted by the Learning Innovation and Lifetime Education (LILE) group at Duke University, and I, Nicole Corbin, instructional designer at NSF Unidata, had the pleasure of attending. This year's event was packed with thoughtfully curated topics relevant to the NSF Unidata higher education community, including AI and workforce development.

netCDF vs Zarr, an Incomplete Comparison

09 September 2024

At NSF Unidata, we have been supporting and developing netCDF standards and packages since the original release of netCDF in 1990. We strongly believe in the usefulness of netCDF Common Data Model for Earth Systems Science data, and for other types of data! NetCDF files can be used efficiently in machine learning modeling applications and can be used as a virtual Zarr datasets.

NSF Unidata has been urged by our community to investigate options to allow netCDF to work more easily with modern cloud-based infrastructure. Based on the strong interest and rapid adoption of Zarr by the community, the netCDF team decided to begin working with the Zarr community to ensure that these two widely used data storage mechanisms can interoperate if necessary.

Convolutional Neural Networks (CNNs) for Earth Systems Science

06 June 2024

Process of conovolving a filter with an image

Convolutional Neural Networks (CNNs) are a powerful class of deep learning models widely applied in Earth science for image analysis, classification, and regression problems. Leveraging the Keras framework in python, CNNs can efficiently process and extract spatial features from 2D and 3D remote sensing, model output, and other Earth Systems Science (ESS) data types.
