Satellite-to-Irradiance Modeling – A New Version of the SUNY Model

This article presents and validates the latest version of the SUNY model for using satellite imagery to calculate irradiance. The new version includes an improved treatment of clear sky, the ingestion of now-casting numerical weather predictions, and a more effective treatment of the model’s dynamic range to better represent extreme (clear and overcast) conditions. This new version results in substantial performance improvements across a diversity of climates.
