Equatorial Plasma Bubble Velocity Estimation over Southeast Asia

Kurzfassung

A method to estimate the drift velocity and direction of equatorial plasma bubbles (EPB) is presented. The method employs the dynamic time warping (DTW) algorithm on global navigation satellite system (GNSS) data collected by nine Closely spaced receivers Of the Singapore satellite positioning reference network (SiReNT). EPB drift velocity field maps are computed from detrended slant total electron content (STEC) measurements. and an uncertainty analysis is combined With a directional filtering to ensure reliability. The estimated drift velocities range from 40 m/s to m/s, which is consistent With typical values found in the South-east Asia region.
