We developed a deep convolutional neural network-based program code that automatically detects equatorial plasma bubbles (EPBs), segments EPB morphologies, and then extracts their features (including EPBs' northernmost foot latitudes and zonal drift velocities) from OI 630 nm airglow images. From 2012 to 2022, all-sky airglow images from Qujing Station, China (geographic: 25°N, 104°E; geomagnetic: 15.1°N, 176.7°E), were manually labeled as EPBs or non-EPBs. Some images showing typical EPB morphologies also had their contours annotated. This...
