Sea Level Fingerprints from Future Polar Ice Melt Under RCP Scenarios

NASA/JPL's ISSM-SESAW module was used to generate high-resolution sea level fingerprints in response to projected 21st-century polar ice sheet mass changes under RCP 4.5 and 8.5 scenarios. The research explores the sensitivity of these fingerprints to different Earth models and spatial resolutions of ice mass change. It also estimates sea level contributions from individual ice basins for specific coastal cities like Perth.

Use Cases

• Modeling regional sea level rise impacts based on high-resolution fingerprint data.
• Assessing coastal city vulnerability based on estimated contributions from specific ice basins.
• Comparing sea level projections under different RCP 4.5 and 8.5 climate scenarios.
• Analyzing the sensitivity of sea level predictions to different 1-D elastic Earth models.

Strengths

• Uses a high-resolution modeling module (ISSM-SESAW) developed by NASA/JPL.
• Projects sea level changes for the entire 21st century under two defined RCP scenarios.
• Includes analysis for specific coastal cities of interest, such as Perth.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or modeling bias inherent to the source platform and methodology.
