Title: STCE Annual Meeting 2009: K geomagnetic activity index - nowcast and forecast
Authors: STANKOV, S. (RMI); STEGEN, K. (RMI); WARNANT, R. (RMI)
Abstract:

A new empirical model has been developed for use in the nowcast and forecast of a proxy to the traditional K index. This model utilizes both space-based observations (of the solar wind) and local ground-based measurements (of the geomagnetic field); hence, it is referred to as the Hybrid K model and was originally developed for the RMI Geophysical Centre at Dourbes (50.1°N, 4.6°E). Preliminary tests showed that the model’s error for the nowcast is around 0.38 KU (K unit) and the error for one hour-ahead prediction is approximately 0.58 KU.
