Pre-Delta-X AVIRIS-NG Surface Reflectance for Mississippi River Delta

Surface spectral reflectance data was collected over the Atchafalaya and Terrebonne basins of the Mississippi River Delta in Louisiana, USA. The dataset includes georectified images and BRDF-adjusted composite mosaics from the AVIRIS-NG airborne spectrometer, captured during the 2015-2016 Pre-Delta-X campaign. This dataset is hosted by ORNL_CLOUD and appears on multiple authoritative platforms.

Use Cases

• Analyzing land cover change and sediment dynamics in deltaic environments using spectral reflectance.
• Calibrating or validating satellite-derived surface reflectance products with airborne data.
• Studying Bidirectional Reflectance Distribution Function (BRDF) effects on reflectance measurements over heterogeneous landscapes.
• Monitoring wetland health and vegetation properties through spectral signatures.

Strengths

• Data is processed to Level 2 (L2), providing Lambertian-equivalent surface reflectance and BRDF-adjusted mosaics.
• Imagery was acquired by the AVIRIS-NG instrument, known for high spectral resolution.
• Presence on multiple authoritative platforms (nasa_earthdata, datagov) signals importance and reliability.

Limitations

• Specific row counts, file sizes, and a complete column list are not provided by any source.
• Sources conflict on the last updated date: one lists 2016-10-22, another lists 2026-03-12.
