Hawaiʻi Climate Data Portal
The Hawaiʻi Climate Data Portal (HCDP) provides open-access climate data and tools to support planning and decision-making across the Hawaiian Islands.

Whatʻs New:
- 🌈 2025 Hawaiʻi Annual Climate Report: A comprehensive, plain-language summary of the year’s rainfall, temperature, and drought. Available as a Flipbook or an Interactive Website.
- 📊 Monthly Updates: Starting Spring 2026, we will offer monthly climate summaries. Subscribe to HCDP Updates.
SAGE3
SAGE3 is an open-source platform designed to help individuals and teams collaborate effectively—with each other and with AI—to accelerate the process of understanding, problem-solving, and discovery.
SAGE3 supports translational and convergent research, making it ideal for integrating insights from science, technology, community knowledge, and policy to tackle real-world challenges. It enables people to work with large and varied information sources—collaborating seamlessly with AI to reach decisions more quickly, clearly, and confidently.

PyForestScan
PyForestScan is a Python library for analyzing and visualizing forest structure using airborne 3D point cloud data. It facilitates the extraction of essential forest metrics—such as canopy height, plant area index (PAI), canopy cover, plant area density (PAD), and foliage height diversity (FHD)—to help researchers and land managers better understand forest composition, health, and ecological processes. By offering a streamlined workflow for processing and interpreting point cloud data, PyForestScan is a powerful and user-friendly tool for those seeking detailed insights into forest ecosystems.

HCDP History & Background
The Hawaiʻi Climate Data Portal (HCDP) is the result of over a decade of collaborative research and technical innovation. It officially launched on March 3, 2022, following extensive development supported by the NSF EPSCoR Track-1 ʻIke Wai project. Today, the portal continues to grow through the sustained support of the NSF EPSCoR Track-1 Change HI project, ensuring it remains a cutting-edge resource for the Pacific.
Global Impact and Reach
Since its inception, the HCDP has become a vital hub for researchers, policymakers, and the public. In its inaugural year alone, the portal saw significant global engagement:
Expanding the Network
A cornerstone of the HCDP’s evolution is the integration of the NSF Hawaiʻi Mesonet project. This initiative is currently expanding the state’s observational backbone by establishing 100 new climate stations across the islands. This infrastructure provides high-resolution, real-time data that was previously unavailable. Following this successful model, expansion efforts are underway in American Samoa, with further plans to seek funding for a similar mesonet in Guam.
The Future of Climate Monitoring
As the HCDP matures, its capabilities continue to expand beyond rainfall and temperature. Development is currently focused on:
- Accessibility: Translating complex climate data into plain-language reports to better serve Hawaiʻi’s diverse communities.
- Advanced Mapping: Introducing hourly wind speed and solar radiation data.
- Decision Support: Creating specialized tools for wildfire risk assessment and drought forecasting.
Publications
Researchers have published and presented many articles and abstracts related to the research done throughout the Change HI project. Below is a list of project publications.
