S1 provides a list of imagery used in this study, a supporting map with Landsat Path/Row, and terminus position shapefiles for all study glaciers. S2 combines relevant glacier information from RGI v6.0 with this study’s alphanumeric identifiers, quantified surge characteristics, and allocated surge-type classifications from the study. S3 provides the terminus position time series graphs normalized by glacier length that were used to classify the study glaciers.
