Moulin Distributions on the Southwest Greenland Ice Sheet from 2016 to 2021

Moulins mapped from 10-meter resolution Sentinel-2 satellite imagery over six years support research on ice sheet hydrology. The dataset includes snapped moulin positions, recurrence data, and associated catchment and meltwater runoff information. Yuhan Wang created this resource to accompany a manuscript under review for the Journal of Geophysical Research - Earth Surface.

Use Cases

• Analyzing interannual moulin distribution patterns based on satellite-derived and snapped moulin positions.
• Modeling meltwater runoff impacts using provided surface runoff calculations from the MAR model.
• Conducting geographically weighted regression (GWR) analysis on moulin formation drivers using the provided GWR variables.
• Studying moulin recurrence and stability over time based on the recurring moulin data.
• Mapping internally drained catchments (IDCs) associated with individual moulins for hydrological modeling.

Strengths

• Data spans six years (2016-2021), enabling temporal trend analysis.
• Includes multiple derived datasets (e.g., snapped moulins, recurrences, catchments) for comprehensive analysis.
• Accompanied by Jupyter Notebooks and Python scripts to reproduce manuscript analyses and figures.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 41.1 MB size suggests a relatively small dataset for geospatial analysis.
