AMSRIce03: Surface Roughness Over Sea Ice

Barrow, Alaska is the location for this collection of surface roughness measurements over sea ice. The data were gathered during the joint in situ and aircraft AMSRIce03 campaign. It supports research on sea ice properties and their interaction with remote sensing.

Use Cases

• Validating satellite-derived sea ice roughness estimates based on in-situ measurements.
• Analyzing spatial variability of surface roughness for climate modeling.
• Calibrating airborne sensor data collected during the AMSRIce03 campaign.

Strengths

• Data originates from a NASA-organized joint in situ and aircraft campaign.
• Cross-platform presence on datagov and nasa_earthdata signals importance and persistence.

Limitations

• Documentation was provided solely by Principal Investigators and not reviewed by NSIDC, suggesting potential gaps.
• Key metadata such as row count, column names, and exact file size are unknown across all sources.
• There is a conflict in last updated dates, with datagov showing 2026 and nasa_earthdata showing 2003.
