This paper proposes an extension to Baguan-solar, named Baguan-solar-Rapid, to enable sub-hourly nowcasting of solar irradiance using rapid-scan satellite data from Himawari-8/9 AHI. The proposed method includes a three-stage architecture: a rapid-scan feature encoder, a temporal super-resolution module, and a physics-informed irradiance decoder. The method is evaluated against baselines using SURFRAD and CLDAS data, with anticipated improvements in RMSE.
Key findings
Proposes Baguan-solar-Rapid for sub-hourly solar irradiance nowcasting.
Introduces a three-stage spatiotemporal fusion architecture for fine-scale cloud dynamics.
Anticipates 12-18% RMSE improvements over existing sub-hourly methods.
Limitations & open questions
The paper is a research proposal and does not include empirical results or a full evaluation of the proposed system.
