Arctic Sea Surface Reflectance Measurements for Satellite Validation, 2012

AMD_KOPRI collected in-situ sea surface reflectance data during the ARAON research cruise from July 9 to September 22, 2012. The dataset was gathered to calibrate and validate ocean color satellite data, using hyperspectral radiometers to measure apparent optical properties. Measurements include downward irradiance (Lu) and upwelling radiance (Ed) to calculate remote sensing reflectance.

Use Cases

• Calibrating ocean color satellite algorithms based on in-situ reflectance measurements.
• Validating satellite-derived remote sensing reflectance (Rrs) using concurrent hyperspectral radiometer data.
• Studying bio-optical properties in the Arctic Ocean based on the described measurement campaign.
• Modeling light penetration in ocean water based on measurements taken to the euphotic depth.

Strengths

• Data collection spans a specific 75-day period from July 9 to September 22, 2012.
• Measurements were taken for satellite calibration/validation, indicating a focused scientific purpose.
• Instruments used are specified: hyperspectral radiometers (HPRO II and HSAS).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
