📄️ Version 1.0
A regional solar irradiance model that predicts multiple components of solar radiation with coverage of North & South America (80°S to 80°N, -5°W to -150°W).
📄️ Version 2.0
This version of the model expands geographic coverage of the model to global (80°S to 80°N).
📄️ Evaluation
In evaluation against high-quality measurements from SURFRAD and SOLRAD networks, Helios analysis outperforms government models by over 20%. Across all times and locations, Helios has lower error and higher correlation with observations than NOAAʼs High-Resolution Rapid Refresh (HRRR) or Global Forecast System (GFS).
