Temporary Availability

This dataset has been added on branch lb/260331_new_datasets. Data are temporarily available using this branch and will be made available on main once the dataset is migrated from a temporary staging area (accessible on av17) to the public space on av17.

---

This dataset is now available and includes the following subdatasets:

• melt_rate: 2D static basal melt rate field. Loaded as an xarray DataArray.
• timeseries: Processed timeseries of monthly and annual basal mass balance for individual ice shelves. Loaded as a Pandas Dataframe that can be filtered for individual shelves.
• masks: Polygons for individual ice shelf masks. Loaded as a GeoPandas Dataframe that can be filtered for individual shelves.

These subdatasets can be accessed using the following commands:

catalog.load_dataset('annual_ice_shelves_mass_balance', version = 'v1', subdataset = 'melt_rate')
catalog.load_dataset('annual_ice_shelves_mass_balance', version = 'v1', subdataset = 'timeseries')
catalog.load_dataset('annual_ice_shelves_mass_balance', version = 'v1', subdataset = 'masks')
