Description
From July to August 2000, this dataset contains in-situ measurements from floodplain lakes (varzea and igapo) of the Solimões and Negro Rivers in the central Amazon basin, Brazil. It includes bidirectional reflectance factor (BRF) spectra recorded at 3 nm intervals from 400 to 900 nm, alongside concurrent water quality parameters like Secchi depth, water temperature, total suspended solids, chlorophyll, and dissolved organic carbon. The data is structured across two comma-delimited files.
Use Cases
Calibrating satellite water quality algorithms based on in-situ spectral reflectance.
Modeling light attenuation and primary productivity in Amazonian floodplain lakes.
Analyzing relationships between optically active components (chlorophyll, DOC, TSS) and spectral signatures.
Comparing water optical properties between white-water (varzea) and black-water (igapo) floodplain environments.
Strengths
Provides high-resolution spectral data (3 nm intervals across 400-900 nm).
Includes concurrent, co-located measurements of multiple water quality parameters.
Covers two distinct and ecologically important Amazonian floodplain types.
Limitations
Metadata completeness is low: column names and row counts are unspecified.
Temporal coverage is limited to a single two-month period in 2000.
Conflicting license information exists between platforms (other-license-specified vs. null).
