Inherent Optical Properties (IOP) data describe how seawater absorbs and scatters light. The dataset includes variables like total absorption and backscattering coefficients, derived from the NOAA-20 VIIRS satellite using the GIOP model framework. It is produced by OB_CLOUD and represents version 2022.0.
Use Cases
- Classifying water types by analyzing spectral slopes like adg_s and bbp_s.
- Assessing water clarity and turbidity using the total backscattering coefficient (bb).
- Estimating phytoplankton biomass from the phytoplankton absorption coefficient at 445 nm (aph_445).
- Quantifying uncertainty in IOP retrievals for error analysis using fields like aph_unc_445 and bbp_unc_445.
- Studying colored dissolved organic matter (CDOM) dynamics via the combined absorption coefficient adg_445.
Strengths
- Provides global spatial coverage from satellite observations.
- Includes uncertainty estimates for key retrieved parameters like aph_unc_445.
- Derived using a standardized model framework (GIOP) for consistency.
Limitations
- Specific row count, temporal range, and spatial resolution are unknown.
- Relies on satellite-derived Remote Sensing Reflectance, which can be affected by atmospheric conditions.
- Uncertainty in the fractional mean Rrs difference (rrsdiff) variable is not clearly defined.
