Inherent Optical Properties (IOP) data quantify how seawater absorbs and scatters light, independent of viewing conditions. The dataset is derived from Sentinel-3B OLCI Level-2 Full Resolution spectral reflectance using the Generalized Inherent Optical Properties (GIOP) model framework. This activity was informed by the U.S. Government's interagency Satellite Needs Working Group (SNWG).
Use Cases
- Water-type classification based on inherent optical properties like absorption and backscattering coefficients.
- Water-clarity assessment based on total absorption and backscattering coefficients.
- Biogeochemical studies based on phytoplankton and CDOM/detritus absorption coefficients.
- Forward/adjoint radiative-transfer applications based on per-pixel inherent optical properties.
- Cross-sensor comparisons based on IOPs, which are more robust than apparent optical properties.
Strengths
- Provides per-pixel inherent optical properties, which are independent of illumination or viewing geometry.
- Enables more robust cross-sensor comparisons than purely apparent optical property products.
- Derived using the Generalized Inherent Optical Properties (GIOP) model framework.
Limitations
- Row count, file formats, and column-level documentation are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
