Peace-Athabasca Delta Water Quality and Reflectance 2010-2011

NASA's dataset documents water quality and spectral reflectance from the Peace-Athabasca Delta in Canada. It contains measurements from 62 unique sites in 2010 and 99 sites in 2011, with many sites revisited across the two-year study period. The data is structured across three comma-delimited files covering site characteristics, water chemistry, and surface reflectance.

Use Cases

• Calibrating satellite-derived water quality models using in-situ measurements of chlorophyll, turbidity, and suspended solids.
• Analyzing spatial and temporal variability in water chemistry across a complex delta system with site revisit data.
• Studying the relationship between water surface spectral reflectance and concurrent in-situ water quality parameters.
• Monitoring changes in surface water processes and characteristics in a northern freshwater delta environment.

Strengths

• Includes spectral reflectance data paired with in-situ water quality measurements for 2011.
• Provides multi-year coverage with 62 sites in 2010 and 99 sites in 2011, enabling temporal analysis.
• Sites were visited 1-4 times within a season, offering intra-annual data points.

Limitations

• Specific column names and row counts are not provided by any source, limiting precise structural understanding.
• Sources conflict on the last updated date: one lists 2011-07-06, another lists 2026-03-12 (likely a metadata refresh).
• The license is specified only as 'other-license-specified' without detailed terms.
