Ocean Color and Aerosol Data from ADEOS Satellite

700-meter resolution data from the ADEOS satellite's Ocean Color and Temperature Scanner provides normalized water-leaving radiance at five visible wavelengths and aerosol properties at three near-infrared bands. The dataset was produced by Japan's National Space Development Agency (NASDA) from the short-lived ADEOS mission, which operated from August 1996 until its failure in June 1997. It contains geophysical parameters derived from Level 1B data, including aerosol optical thickness and correction factors.

Use Cases

• Estimate chlorophyll-a concentration by modeling its relationship with normalized water-leaving radiance at 443 nm and 490 nm.
• Analyze aerosol transport over oceans using aerosol optical thickness at 865 nm and aerosol radiance at 670, 765, and 865 nm.
• Study coastal water quality by tracking spatial patterns in water-leaving radiance across the 412-565 nm spectral bands.
• Validate atmospheric correction algorithms for ocean color sensors using the provided epsilon of aerosol correction at 670 and 865 nm.
• Map global ocean optical properties for a specific historical period using the 1400 km observation swath data.

Strengths

• Provides 12 spectral bands of data from visible to thermal infrared regions.
• Offers high spatial resolution of 700 meters per pixel.
• Includes derived geophysical parameters like aerosol optical thickness, reducing preprocessing needs.

Limitations

• Extremely limited temporal coverage, with data collection ending abruptly in June 1997 after less than a year.
• Potential data gaps or quality issues due to the satellite's power failure and mission termination.
• Unknown sample size and specific record count for the derived product.
