Statistical correlation analysis of strong earthquakes and ionospheric electron density anomalies as observed by CSES-01

In this work, we preliminary analyse ionospheric electron density
as observed by the first China Seismo-Electromagnetic Satellite (CSES-01) from
April 2018 to July 2019, defining an anomaly along each track objectively. We then
apply a worldwide statistical correlation in space and time of these anomalies with
respect to M5.5+ shallow earthquakes (USGS source) occurred in the same period.
Although the data are short and cover discontinuously the period of concern, in
general, the preliminary results seem to confirm those obtained with an analogous
analysis on the Swarm satellite data recently published in De Santis A. et al., Sci.
Rep., 9, (2019) 20287.
