abstract = "The purpose of this study is to present a wavelet interactive
filtering and reconstruction technique and apply this to the solar
wind magnetic field components detected at the L1 Lagrange point
~0.01 AU upstream of the Earth. This filtered interplanetary
magnetic field (IMF) data is fed into a model to calculate a time
series which we call AE*. This model was adjusted assuming that
magnetic reconnection associated with southward directed IMF Bz is
the main mechanism transferring energy into the magnetosphere. The
calculated AE* was compared to the observed AE index using cross
correlation analysis. The results show correlations as high as
0.90. Empirical removal of the high-frequency, shortwavelength
Alfv{\'e}nic component in the IMF by wavelet decomposition is
shown to dramatically improve the correlation between AE* and the
observed AE index. It is envisioned that this AE* can be used as
the main input for a model to forecast relativistic electrons in
the Earth's outer radiation belts, which are delayed by ~1 to 2
days from intense AE events.",
