IBM and NASA have launched a groundbreaking weather and climate model named Prithvi-WxC, designed to integrate with existing Earth Observation models to enhance complex forecasting capabilities.

Officially released as an open-source tool on September 23, 2024, after four months of development, Prithvi-WxC aims to provide advanced scientific data for researchers globally.

Built on 40 years of NASA's MERRA-2 dataset, the model enhances accuracy in weather predictions and climate modeling, making it adaptable to various scales.

Karen St. Germain, director of NASA's Earth Science Division, emphasized the model's importance in delivering actionable science to address urgent climate challenges.

NASA Administrator Bill Nelson highlighted the role of Artificial Intelligence in this initiative, which aims to improve weather detection capabilities.

Prithvi-WxC employs a hybrid architecture, utilizing a vision transformer and masked autoencoder to effectively analyze spatial and temporal data.

The model's flexibility allows it to adapt to diverse inputs, making it suitable for applications ranging from hurricane forecasting to assessing climate risks.

Researchers can access Prithvi and its specialized models through Hugging Face, promoting collaboration and data sharing within the scientific community.

This initiative aligns with the Biden administration's focus on public-private partnerships to drive innovation in climate science.

Training involved reconstructing heavily blacked-out climate data, teaching the model to fill in gaps similar to human forecasters.

The model is expected to address complex forecasting tasks, including crop yield predictions and assessing extreme flooding impacts.

In addition to weather forecasting, the model also includes functionalities for estimating gravity waves, which can impact weather patterns.
