IceBridge Sea Ice Freeboard, Snow Depth, and Thickness Measurements

IceBridge L4 Sea Ice Freeboard, Snow Depth, and Thickness V001 contains derived geophysical data products from NASA's Operation IceBridge campaigns. The NSIDC_CPRD organization produced this data set, which was last updated in April 2013. It includes measurements retrieved from Snow Radar, Digital Mapping System (DMS), Continuous Airborne Mapping By Optical Translator (CAMBOT), and Airborne Topographic Mapper (ATM) instruments.

Use Cases

• Modeling sea ice thickness from freeboard and snow depth measurements to assess ice volume changes.
• Analyzing spatial patterns of snow depth on sea ice across Greenland and Antarctica.
• Validating satellite-derived sea ice products using high-resolution airborne data from instruments like Snow Radar and ATM.
• Investigating the relationship between freeboard and thickness for different ice types in polar regions.

Strengths

• Data integrates measurements from multiple advanced airborne instruments (Snow Radar, DMS, CAMBOT, ATM).
• Provides key derived geophysical variables (freeboard, snow depth, thickness) for polar sea ice.

Limitations

• Data collection ended with the last update in 2013, limiting temporal analysis to past conditions.
• Specific row counts, file sizes, and spatial resolution details are not provided in the input.
