S-band waveguide measurements of sea-ice samples ranging from 2.6 to 3.95 GHz during the S

2012 data from the SIPEX II voyage contains S-band waveguide measurements of sea-ice samples between 2.6 and 3.95 GHz. The dataset includes scattering parameters from a portable network analyzer, sample temperature readings, and photographs of crystallography cores. It was collected by researchers affiliated with the Australian Antarctic Data Centre (AU_AADC) during the Aurora Australis marine science expedition.

Use Cases

• Calibrating satellite-based sea-ice thickness retrievals based on measured complex permittivity.
• Modeling microwave scattering from sea ice using recorded S11 scattering parameters.
• Correlating ice salinity and crystallography with electromagnetic properties based on the described sample analysis.
• Assessing anisotropy in sea-ice dielectric properties using the vertical (V) and off-vertical (H) sample measurements.

Strengths

• Includes paired measurements for vertical and orthogonal (off-vertical) sample orientations to assess field components.
• Samples were precisely sized (7 cm X 3 cm X 1.9 cm) to fit the waveguide and minimize spurious reflections.
• Data is available in both raw and reformatted formats for ease of import into Matlab.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2012-10-31 23:59:59.999000; freshness should be verified.
• Row count and total sample size are unknown, which may limit suitability assessment.
