From: GPS and in situ Swarm observations of the equatorial plasma density irregularities in the topside ionosphere

Examples of the concurrent LP and GPS data analysis during evening LT period for cases of the plasma irregularities detection (a, d), quiet-time equatorial ionization anomaly (b, e), storm-enhanced equatorial ionization anomaly (c, f). Mark like “SWA-G07” means the data along line-of-sight between SWA and GPS PRN 7. TEC data are the relative slant TEC measurements. Detrended ROT/ROTI are shown in units of TECU/min, ROD/RODI—in units of 106 el/(cm3 min)
