ADEOS-I OCTS Level-3 Global Mapped Inherent Optical Properties (IOP) Data provides per-pixel coefficients for seawater absorption and backscattering of light. The dataset is produced by OB_CLOUD using the Generalized Inherent Optical Properties (GIOP) model framework applied to spectral Remote Sensing Reflectance. The last update for this version was in June 1997.
Use Cases
- Classify water types by analyzing spatial patterns in the total absorption coefficient (a) and total backscattering coefficient (bb).
- Assess phytoplankton biomass distribution using the phytoplankton absorption coefficient at 443 nm (aph_443).
- Study colored dissolved organic matter (CDOM) dynamics via the combined CDOM and detritus absorption coefficient (adg_443) and its spectral slope (adg_s).
- Model underwater light fields for radiative transfer applications using the suite of absorption and backscattering coefficients.
- Evaluate retrieval uncertainty for particulate backscattering by examining the bbp_unc_443 field alongside bbp_443.
Strengths
- Provides globally mapped, per-pixel geophysical variables for ocean optics.
- Includes uncertainty estimates for key parameters like aph_unc_443 and adg_unc_443.
- Derived using a standardized model framework (GIOP) supporting cross-sensor comparisons.
Limitations
- Data is from 1997, representing a single historical satellite mission with no recent updates.
- Specific row count, spatial resolution, and file size details are unknown.
- The dataset's utility may be limited for studying contemporary oceanographic changes.
