Use of principal component analysis for identification of temporal and spatial patterns in the dynamics of ionospheric equatorial anomaly
2015
Journal of Physics, Conference Series
In this paper we describe results of the principal components analysis of the dynamics of Total Electronic Content (TEC) data with the use of global maps presented by the Jet Propulsion Laboratory (NASA, USA) for the period of 2007-2011. We show that the result of the decomposition in principal components essentially depends on the method used for preprocessing the data, their representation (the used coordinate system), and the data centering technique (e.g., daily and seasonal components
