Dayside Aurora Dataset from the GOLD Mission

This dataset contains dayside aurora observations derived from measurements by the Global-scale Observations of the Limb and Disk (GOLD) mission. The source data are from the Level 1C DAY (L1C DAY) products, available on the official GOLD website and at NASA’s Space Physics Data Facility (SPDF).<br>GOLD is onboard a geostationary satellite at 47.5°W longitude. Due to its viewing geometry and the positioning of the geomagnetic poles, the southern aurora is generally not visible in the L1C DAY files. Consequently, this dataset only has products of the northern aurora.The dataset includes three main products:Raw emissions of auroral species from the L1C DAY files.Dayglow estimates - representing light pollution (non auroral emissions) that contaminate the images.Binary Masks - Estimated auroral locations in the images.Subtracting (2) from (1), and applying (3), gives the dayside aurora estimate, with no dayglow contamination.In total, the dataset consists of over 47,000 image-label pairs spanning October 2018 to June 2025, making it one of the largest publicly available dayside aurora datasets to date.
