ADEOS-I OCTS Level-2 Inherent Optical Properties (IOP) Data, 1997

ADEOS-I OCTS Level-2 Regional Inherent Optical Properties (IOP) Data, version 2022.0, provides per-pixel inherent optical properties retrieved from satellite-measured Remote Sensing Reflectance. The data, from the OB_CLOUD organization, includes coefficients for total absorption, phytoplankton absorption, and particulate backscattering, among other variables. It was last updated on 1997-06-30.

Use Cases

• Classifying water types based on inherent optical properties like absorption and backscattering coefficients.
• Assessing water clarity and quality using the total absorption and backscattering coefficients.
• Conducting biogeochemical studies by analyzing phytoplankton absorption (aph_443) and CDOM/detritus absorption (adg_443).
• Performing cross-sensor comparisons for satellite ocean color data using the IOP framework.
• Supporting forward and adjoint radiative-transfer applications with per-pixel optical property inputs.

Strengths

• Provides a suite of geophysical variables including total absorption (a), total backscattering (bb), and phytoplankton absorption at 443 nm (aph_443).
• Includes uncertainty estimates for key variables like aph_unc_443 and bbp_unc_443.
• Derived using the Generalized Inherent Optical Properties (GIOP) model framework, which supports robust cross-sensor comparisons.

Limitations

• Last updated 1997-06-30 23:59:59; freshness should be verified.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
