Polar UVI Images (Intensity and Boundary) & Space Physical Parameters Joint Data

The ultraviolet imager on board the Polar satellite is capable of capturing information about the polar and equatorial boundaries of the auroral oval, the overall morphology of the auroral oval, and the spatial distribution of auroral oval intensity. The intensity of the auroral oval are related to the amount of energy injected from the solar wind and magnetosphere into the polar ionosphere. And the position and size of the auroral oval boundary is also closely linked to changes in the space environment. In order to mitigate the influence of daylight on auroral images, we selected a total of 4215 images of both full, gap and incomplete aurora ovals. We utilized corresponding Interplanetary Magnetic Field (IMF), solar wind parameters, and geomagnetic index data from the NASA OMNI database to build a jointly dataset consist of the space physical parameters and the intensity and boundaries of the aurora oval.
