Data for reproducing error metric comparison for the journal article "Data-driven forecasting of aeolian dust impacts on solar irradiance and PV output over the Eastern Mediterranean"

The dataset includes: PV Proxy (GHI W/m²): Photovoltaic-derived proxy for global horizontal irradiance. CAMS (W/m²): Global horizontal irradiance from Copernicus Atmosphere Monitoring Service reanalysis. XGBoost (W/m²): Machine learning–based irradiance predictions derived from atmospheric and surface variables. The data are spatially aggregated to a regular grid and temporally aligned to enable direct comparison between observations, reanalysis products, and model outputs. These processed datasets support the reproducibility of the results presented in the associated publication.
