Spectral Fidelity of Earth's Ecosystems: Reflectance and Aerosol Data

Source data from the manuscript 'Spectral Fidelity of Earth’s Terrestrial and Aquatic Ecosystems' includes reflectance spectra, aerosol models, and a six-dimensional aquatic reflectance lookup table. The data is associated with research from the Jet Propulsion Laboratory and uses formats from the ISOFIT forward model. Specific file counts and row numbers are not provided in the description.

Use Cases

• Calibrating the ISOFIT forward model based on provided aerosol and surface model files.
• Analyzing spectral reflectance for terrestrial ecosystems using the provided PLSR and reflectance CSV files.
• Simulating water-leaving reflectance for aquatic systems using the six-dimensional Hydrolight lookup table.
• Resampling spectral data to a common wavelength grid as demonstrated by the veg_reflectances_resampled.txt file.

Strengths

• Includes a six-dimensional lookup table for aquatic reflectance, indexed by solar zenith, windspeed, chlorophyll-a, cdom, minerals, and wavelengths.
• Provides specific source citations for core data files, such as Chadwick et al., Methods in Ecology and Evolution 2020.
• Uses standardized formats like ISOFIT and MODTRAN templates for atmospheric modeling components.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.

Provenance
