Polarimetric Validation Data for PACE Observatory

Data from the Naval Research Laboratory and City College of New York supports validation of the PACE Observatory's neural network algorithm for ocean color retrieval. The dataset includes measurements of polarized radiance, attenuation and absorption coefficients, particle size distributions, and seawater optical properties. Its presence on NASA EarthData and Data.gov indicates its importance for satellite calibration.

Use Cases

• Validating neural network algorithms for retrieving the c/a ratio from combined OCI and HARP-2 satellite measurements.
• Characterizing uncertainty in polarized radiation measurements for atmospheric correction models.
• Analyzing particle size distributions and shapes to understand their impact on ocean light scattering.
• Studying seawater inherent optical properties and constituents like chlorophyll fluorescence.
• Calibrating and assessing the performance of the Hyper-Angular Research Polarimeter 2 (HARP2) instrument.

Strengths

• Dataset is hosted on multiple authoritative platforms (NASA EarthData, Data.gov), signaling recognized importance.
• Supports validation for a specific, peer-reviewed neural network algorithm (Agagliate et al., 2023).
• Covers a suite of advanced oceanographic measurements including polarized radiance, IOPs, and particle analysis.

Limitations

• No column names, row counts, or file sizes are provided on any platform, limiting technical assessment.
• Conflicting license information: one source lists 'other-license-specified', another lists 'None'.
• Specific temporal and geographic coverage for the measurements is not detailed.
