Geomagnetic Storm (K≥5)

Evaluation of the SIDC forecast and models to predict a geomagnetic storm with K at least 5, across the years from 2004 on.
Measures are the probability of detection (POD, top row) and proportion correctness (PC, middle row) for all forecasts, and the Heidke Skill Score (HSS, top row) and the True Skill Statistic (TSS, middle row) for the SIDC forecast.
The lower row visualizes the proportion of days with an event, a hit, a miss and a false alarm. the proportion of hits and the proportion of misses sum up to the number of events.
