Simulated Arctic Sea Ice Data for ESA CryoRad Mission, April 2024

Nine simulated microwave brightness temperature channels at frequencies from 0.4 to 2.0 GHz for the potential ESA CryoRad mission. The 4.8 GB dataset contains geophysical fields and simulated brightness temperatures for the Arctic on April 8th, 2024, generated by Josephine Juul using the SMRT model and DMI inputs. Each NetCDF file represents one full satellite orbit, covering a swath width of approximately 160 km.

Use Cases

• Training machine learning models for sea ice thickness retrieval based on simulated multi-frequency brightness temperatures.
• Validating radiative transfer models for snow-covered sea ice based on the described SMRT configuration and geophysical inputs.
• Analyzing spatial patterns of Arctic sea ice properties like concentration and age on a single day.
• Developing sensor fusion or downscaling methods using the provided channel-specific convolved and original-resolution variables.

Strengths

• Includes eight key geophysical variables: sea-ice thickness, snow thickness, snow temperature, air temperature, sea-ice concentration, sea-ice age, sea-ice temperature, and sea-ice salinity.
• Provides simulated brightness temperatures for nine specific microwave channels (0.4 to 2.0 GHz) with channel-consistent spatial representation.
• Contains both convolved and original-resolution ('_orig' suffix) data for direct comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is simulated for a single day (April 8th, 2024) and a specific mission concept, limiting temporal and configurational scope.
