UAVSAR Radar Data for Atchafalaya Basin Water Level Monitoring

Pre-Delta-X: L1 UAVSAR Single Look Complex and Interferograms, MRD, LA, USA, 2016 is a Level 1 dataset containing single look complex stack products and co-registered interferograms. The data were collected by NASA's UAVSAR L-band radar on a Gulfstream-III aircraft over the Atchafalaya Basin in Louisiana during October 2016. A single flight line was sampled six times at roughly 30-minute intervals to observe changing water levels.

Use Cases

• Analyzing water level changes in a coastal basin using time-series interferograms from six sequential flights.
• Studying L-band radar backscatter from wetland vegetation and water surfaces using HH polarization SLC data.
• Developing methods for monitoring surface water processes and inundation extent in complex delta environments.
• Investigating coastal landform changes and sea-level change impacts using geospatial radar imagery.

Strengths

• Data provides high-temporal-resolution monitoring with six samples collected at approximately 30-minute intervals.
• Uses UAVSAR's polarimetric L-band synthetic aperture radar, which is sensitive to vegetation structure and soil moisture.
• Dataset is part of a structured NASA campaign (Pre-Delta-X) focusing on a critical Mississippi River Delta floodplain region.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date, listing both 2016-10-17 and 2026-03 12.
• Data is limited to a single flight line (gulfco_12011) and HH polarization only.
