This paper documents a new package for the Weather Research and Forecasting--Advanced Research WRF (WRF-ARW) model that can simulate any partial, total or hybrid solar eclipse for the period 1950–2050 and is also extensible to a longer period. First, a description of the implementation together with a validation for the period 1950–2050 of all solar eclipse trajectories is presented. Second, the model response is analyzed in four total solar eclipse episodes. Global horizontal irradiance (GHI) outcomes are validated with respect to ground-based measurements.
