This study presents conjunction observations of the equatorial plasma bubbles (EPBs) by L-band scintillation, density fluctuation, vertical plasma drift, and airglow emission at various altitudes in the F layer using the COSMIC-2, SWARM, ICON, and GOLD data. Result shows that locating the EPBs by in-situ measurements highly dependent on the orbit inclinations, thus the EPB occurrence detected by COSMIC-2, SWARM, and ICON display distinct pattern in both temporal and spatial aspects, but these detections are well collocated with the 135.6nm EIA emission gaps in the GOLD monitoring images at Atlantic-Brazilian longitude sector. The collaboration of the COSMIC-2, SWARM, ICON, and GOLD missions provides us rapid and detailed observation of three-dimensional structure of EPBs in Atlantic-Brazilian region. The preliminary results of the vertical drift velocity measured by the ion velocity meter (IVM) at/within the detected EPBs are also compared with the thretical SAMI-3 model.
