Abstract Global horizontal irradiance (GHI) forecasts from the MAD-WRF model. MAD-WRF is a blend two nowcasting systems, MADCast and WRF-Solar to take advantage of the strengths of each model. The model is being run on an hourly basis providing a 6-hour forecasts over the contiguous U.S. Initial and boundary conditions are provided by the High Resolution Rapid Refresh (HRRR) model. The initial cloud field is constrained using retrievals from GOES-16 to impose the cloud mask and the cloud top height, and METAR observations are used to impose the cloud base height. The forecasts files contain the instantaneous GHI every 15 min. The MADCast model is described in Descombes, G., T. D. Auligne, H. -C. Lin, D. Xu, C. S. Schwartz, and F. Vandenberghe, 2014: Multi-sensor Advection Diffusion nowCast (MADCast) for cloud analysis and short-term prediction. NCAR Technical Note NCAR/TN-509+STR, 21 pp, doi:10.5065/D62V2D37.
