Hawaii Ocean Time-series Data for PACE Satellite Validation

Approximately 150 days of high-quality oceanographic data collected across all seasons over a 3-year period. The dataset originates from near-monthly, 5-day expeditions to oligotrophic waters near Oahu, Hawaii, conducted by the Hawaii Ocean Time-series (HOT) program. It is managed by the OB_DAAC organization for validating the PACE Mission.

Use Cases

• Validating PACE satellite ocean color and biogeochemical data products using in-situ measurements.
• Analyzing seasonal variability in ocean temperature, salinity, and density in the North Pacific Subtropical Gyre.
• Studying the relationship between ocean chemistry and optical properties in oligotrophic waters.
• Calibrating remote sensing algorithms for parameters like chlorophyll-a concentration and inherent optical properties.

Strengths

• Collection spans ~30 cruises across all seasons, providing seasonal coverage.
• Data is described as high-quality, collected for the specific purpose of satellite validation.
• The dataset is hosted on multiple authoritative platforms (nasa_earthdata, datagov), indicating its importance.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources disagree on license details: one specifies 'other-license-specified', while another lists 'None'.
• The author and exact data formats beyond ISO and BIN are unknown.
