Data set content 

• {Name}_Global-ts-results*.nc: Data cube in NetCDF (.nc) format containing a time series of glacier speed maps for the selected single glacier {Name}. There are five glaciers analyzed in this study: Abramov, Khumbu, Petrov, Tuyusku, and Yanong.
• {Name}_global-ts-refgeo.gpkg: The footprint of the glacier speed maps for the selected single glacier {Name}. In geopackage format.
• {Name}_flowline_densified200m.gpkg: Selected flowine with vertex interval ~= 200 m for the selected single glacier {Name}. In geopackage format.
• analysis_template.ipynb: Jupyter Notebook file containing template code for users to perform and reproduce basis analysis with the data cubes.
• Readme.md: This readme file.

{Name}_Global-ts-results*.nc file structure

The data cube has a spatial spacing of 120 m (for x and y) and a temporal spacing of 6 days (for time).

Coordinates:

• time: datetime64 object specifying the temporal sampling points.
• x: Easting in a specified CRS. The other two geopackage files use the same CRS as the .nc file.
• y: Northing in a specified CRS.

Data Variables:

• speed: Glacier speed in m/day.
• speed_uncertainty: Uncertainty (1-sigma) of glacier speed in m/day.
• data_gap_days: Temporal duration between the sampling location and the nearest measurement, in days. For example, if data_gap_days is 3 on 2020-01-15, then the nearest speed measurement is either from 2020-01-12 or 2020-01-18.
