Russell Sector Ice Flow Speed from Satellite, 2015-2019

West Greenland's Russell sector is covered by this dataset of horizontal surface ice velocity. It provides bi-weekly averages at 150-meter spatial resolution, derived from Landsat-8, Sentinel-1, and Sentinel-2 satellite imagery collected between 2015 and 2019. The dataset was created by Derkacheva Anna of the Centre National de la Recherche Scientifique.

Use Cases

• Model ice sheet mass balance based on surface flow speed.
• Validate ice flow models using the bi-weekly temporal resolution.
• Analyze seasonal and interannual variability in ice velocity.
• Map ice flow uncertainty using the provided standard deviation maps.
• Study glacier dynamics in a specific sector of the Greenland Ice Sheet.

Strengths

• Derived from three satellite sources (Landsat-8, Sentinel-1, Sentinel-2) for likely robust coverage.
• Provides maps of uncertainty (STD) per velocity component.
• Has a high spatial resolution of 150 meters.
• Covers a continuous 5-year period from 2015 to 2019.

Limitations

• Column-level documentation is absent; field semantics must be inferred from the NetCDF files.
• Row count is unknown, which may limit suitability assessment.
• The description does not specify the exact geographic bounds of the 'Russell sector'.
