Shock Detectives: classifying MMS observations of Earth’s magnetosheath via citizen science
Year: 2026
Type: article
Abstract: We present a dataset of 35,483 unique 1 minute periods ( ∼ 591 h) of quasi-perpendicular and quasi-parallel magnetosheath MMS classifications manually reviewed with the help of citizen scientists. This dataset spans a variety of representative solar wind conditions sampled over the course of 8 years of data on the dayside. We identify 7,697 high likelihood quasi-parallel magnetosheath minute intervals and an additional 2,315 moderate likelihood quasi-parallel intervals. Within this dataset, we also identify 2,677 temporal transitions between quasi-perpendicular and quasi-parallel magnetosheath at 1-min resolution. This rich dataset can be used to perform statistical studies of these two populations and to train machine learning models.
