Missouri Reservoir Hyperspectral and Water Quality Data

Two long-running monitoring programs annually record more than one thousand measurements of nitrogen, phosphorus, chlorophyll-a, Secchi depth, particulate organic and inorganic matter, and cyanotoxins across 100 reservoirs in Missouri, USA. This NASA-funded dataset integrates these in-situ water quality measurements with hyperspectral radiometer data from TriOS RAMSES sensors, collected using an on-water, skylight-blocked approach. The project aims to establish critical links between biogeochemical properties and optical water properties to improve the use of Earth-observing satellite data for inland waters.

Use Cases

• Calibrating and validating satellite-derived water quality products based on in-situ hyperspectral and biogeochemical measurements.
• Modeling the relationship between optical properties (from radiometers) and concentrations of chlorophyll-a or cyanotoxins.
• Analyzing long-term trends in reservoir water quality across the state of Missouri.
• Developing algorithms to estimate particulate organic and inorganic matter from hyperspectral signatures.

Strengths

• Integrates detailed, in-situ hyperspectral radiometry with a comprehensive suite of over one thousand annual water quality measurements.
• Spatial coverage includes 100 reservoirs, providing a broad sample of inland water conditions.
• Data collection follows a standardized on-water (skylight-blocked) approach using calibrated TriOS RAMSES sensors.

Limitations

• Key metadata such as row count, specific column names, and temporal coverage are not provided in any source.
• The license is ambiguously listed as 'other-license-specified' without details, and one source lists no license.
• The last update date (2026-03-12) appears to be a future date, indicating a potential metadata error.
