Surface range values for Antarctica and Greenland are derived from Riegl Laser Altimeter measurements. The data were collected by the ICECAP project, funded by the NSF, NERC, and NASA Operation IceBridge. The dataset was last updated by the NSIDC_CPRD in January 2013.
Use Cases
- Model ice sheet surface topography by analyzing geolocated surface elevation triplets.
- Validate satellite-derived elevation models using high-precision laser altimeter surface range values.
- Study cryospheric evolution by tracking changes in surface elevation over repeated survey lines.
- Calibrate other remote sensing instruments by comparing measurements with laser altimeter-derived surface data.
Strengths
- Data originates from the NASA Operation IceBridge mission and the ICECAP project.
- Provides surface elevation measurements for two major ice sheets: Antarctica and Greenland.
Limitations
- Data recency is limited, with a last update in 2013, potentially missing recent changes.
- Specific data volume, spatial resolution, and temporal coverage within the mission period are unknown.
