A Large Simulation Set of Geomagnetic Storms -- Can Simulations Predict
Ground Magnetometer Station Observations of Magnetic Field
Perturbations?
Abstract
We use the Space Weather Modeling Framework (SWMF) Geospace
configuration to simulate a total of 122 storms from the period
2010-2019. With the focus on the storm main phase, each storm period was
run for 54 hours starting from 6 hours prior to the start of the Dst
depression. The simulation output of ground magnetic variations were
compared with ground magnetometer station data provided by SuperMAG to
statistically assess the Geospace model regional magnetic perturbation
prediction performance. Our results show that the regional predictions
at mid-latitudes are quite accurate, but the high-latitude regional
disturbances are still difficult to predict.
