A New Index to Describe the Response of Geomagnetic Disturbance to the Energy Injection from the Solar Wind
In this paper, we establish a new non-dimensional global geomagnetic disturbance index JpG by applying the spectral whitening method to the horizontal components of geomagnetic fields observed at eight ground-based stations distributed at low and middle latitudes water bottle during years 1998 to 2014.This index can describe the development of geom
