High Mountain Asia Glacier Projections Under RCP Scenarios

High Mountain Asia Rasterized PyGEM Glacier Projections provide gridded data on future glacier mass change and runoff. The dataset is derived from the Python Glacier Evolution Model (PyGEM) and includes components of mass and runoff changes. It was produced by NSIDC_CPRD and last updated in October 2100.

Use Cases

• Project future glacier mass change across High Mountain Asia using gridded mass change data under different RCP scenarios.
• Model regional glacier runoff contributions to river systems using the gridded runoff projection layers.
• Analyze the spatial distribution of specific mass balance components from the rasterized model output.
• Compare the timing and magnitude of peak water from glaciers using the time-series of runoff projections.

Strengths

• Projections include multiple Representative Concentration Pathway (RCP) scenarios for comparative analysis.
• Data is rasterized, providing spatially continuous gridded coverage over the High Mountain Asia region.

Limitations

• Specific temporal coverage, spatial resolution, and the number of model ensemble members are unknown.
• The dataset's utility is contingent on the underlying PyGEM model assumptions and parameterizations.
