mass_change(version=None, hemisphere=None, epsg=None, region=None, spacing=None, registration=None, **kwargs)[source]#

Ice-sheet height and thickness changes from ICESat to ICESat-2 for both Antarctica and Greenland from Smith et al.[1].

Choose a version of the data to download with the format: “ICESHEET_VERSION_TYPE” where ICESHEET is “ais” or “gris”, for Antarctica or Greenland, VERSION is “dhdt” for total thickness change or “dmdt” for corrected for firn-air content. For Antarctic data, TYPE is “floating” or “grounded”.

add “_filt” to retrieve a filtered version of the data for some versions.

Units are in m/yr

Parameters:

  • version (str | None) – choose which version to retrieve, by default is “ais_dhdt_grounded” for Antarctica and “gris_dhdt” for Greenland.

  • hemisphere (str | None) – choose which hemisphere to retrieve data for, “north” or “south”, by default None

  • epsg (str | None) – choose which region to retrieve data for, either “3031” or “3413”, by default None

  • region (tuple[float, float, float, float] | None) – region to clip the loaded grid to, in format [xmin, xmax, ymin, ymax], by default doesn’t clip

  • spacing (float | None) – grid spacing to resample the loaded grid to, by default is 5km

  • registration (str | None) – change registration with either ‘p’ for pixel or ‘g’ for gridline registration, by default is “p”.

  • kwargs (Any) – additional keyword arguments to pass to resample_grid

Returns:

Returns a grid of Antarctic or Greenland ice mass change in meters/year.

Return type:

Any
