| Summary: | Description: The Aurora event data database contains two datasets: "Auroral event data" and "Dayside auroral observation". The dataset of "Auroral event data" has 14 auroral image sequences with a total of 21,372 images (total size: 1.61GB). The 14 aurora image sequences are from 2003 to 2021 as the study data of the "Unsupervised auroral event Segmentation Based on All-sky Imager Observation". The aurora event data are ground-based observation data acquired by three-wavelength (427.8, 557.7, and 630.0 nm) all-sky imaging (ASI) at YRS (the geographic coordinates are 78.92°N, 11.93°E, the corrected magnetic latitude is 76.24°N, MLT=UT+3.1h.) in Ny-Ålesund, Svalbard. The device captures an aurora image every 10 seconds with an exposure time of 7 seconds. The captured raw image is a 14-bit 512×512 pixel image. The angle between the horizontal direction of the ASI image and the magnetic meridian is 61.1°. Data acquisition instruments: In 2003, three all-sky CCD auroral imagers were installed to observe aurora ... |
