Sentinel-1B Level 0 Metadata for Radar Data Processing

Sentinel-1B was launched April 25, 2016 and operated until December 2021. Level 0 products contain compressed, unprocessed radar source packets with auxiliary information, forming the basis for all higher-level products. The metadata in this collection was created by the Alaska Satellite Facility Distributed Active Archive Center from Sentinel-1B SAFE format products.

Use Cases

• Generate higher-level radar imagery products based on Level 0 source packets.
• Analyze satellite orbit and attitude information based on auxiliary data.
• Study radar signal characteristics based on noise and internal calibration packets.
• Process compressed radar data using focusing software based on FDBAQ encoding.

Strengths

• Metadata is ISO compliant XML, suggesting a standardized format.
• Products support four imaging modes with resolutions down to 5 meters.
• Data provides dual polarization capability and short revisit times.
• Level 0 data includes noise, calibration, echo, orbit, and attitude packets.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2021-12-24 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
