ABoVE: UAVSAR P-band Radar Backscatter Data for Alaska and Canada, 2017

74 study sites across Alaska, USA, and western Canada are covered by Level 1 polarimetric radar backscattering coefficient data. The dataset contains 139 data takes from the UAVSAR P-band SAR radar instrument, collected during flight campaigns from May to August 2017 onboard a NASA Gulfstream-III aircraft. The data products are multi-look complex, polarimetrically calibrated, and georeferenced.

Use Cases

• Analyze polarimetric radar backscattering coefficients (Sigma-0) for land cover classification
• Study georeferenced radar data for spatial pattern analysis across Alaska and Canada
• Calibrate or validate other remote sensing models using the provided polarimetrically calibrated data
• Investigate temporal changes in radar signatures from the multiple data takes per site

Strengths

• 139 data takes provide multiple observations for many of the 74 study sites
• Data is polarimetrically calibrated and georeferenced, suggesting a processed, ready-to-use state
• Coverage spans a significant geographic area across Alaska and western Canada

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic/temporal bias inherent to the specific 2017 flight campaigns
