Surface elevation data over parts of Greenland were collected by the NASA Land, Vegetation, and Ice Sensor (LVIS) airborne lidar altimeter. The data were gathered during NASA Operation IceBridge funded campaigns. The dataset was last updated by the NSIDC_CPRD organization in September 2017.
Use Cases
- Model ice sheet surface topography and slope using geolocated elevation points.
- Analyze elevation change over time by comparing with other IceBridge or ICESat-2 datasets.
- Validate and calibrate satellite-derived elevation models from missions like CryoSat-2.
- Study surface features like crevasses or melt ponds through spatial analysis of the point cloud.
Strengths
- Data collected by the specialized NASA LVIS instrument, designed for high-accuracy surface mapping.
- Focus on the Greenland ice sheet, a critical region for climate change studies.
Limitations
- Data recency is limited, with the last update in 2017, preceding newer IceBridge and ICESat-2 campaigns.
- Spatial coverage is partial, limited to specific flight lines over parts of Greenland.
