ADEOS-II GLI 250m Resolution Satellite Imagery

Satellite imagery data from the GLI sensor aboard the ADEOS-II (Midori II) satellite, processed to Level 1B. The dataset includes radiometrically and geometrically corrected observations at a 250-meter resolution across six specific spectral channels. It was produced by the Japan Aerospace Exploration Agency (JAXA), with the last update recorded in October 2003.

Use Cases

• Analyzing land surface properties using the 1640 nm and 2210 nm near-infrared channels.
• Monitoring ocean biological content by examining the 460 nm and 545 nm visible light channels.
• Classifying land and ocean features using the attached Ocean/Land flags.
• Assessing data quality for specific pixels by checking the missing data, saturation, and transient response flags.
• Applying atmospheric corrections using the provided project coefficients for the six spectral bands.

Strengths

• Data is radiometrically and geometrically corrected, providing a calibrated base for analysis.
• Includes quality assurance flags for missing data, saturation, and transient response.
• Covers six specific spectral channels (e.g., 460, 545, 660, 825, 1640, 2210 nm) for targeted feature extraction.
• Sensor has a wide swath of 1600 km, enabling broad spatial coverage per pass.

Limitations

• Data is from 2003, making it temporally stale for contemporary environmental analysis.
• The 250m spatial resolution is coarse for studying fine-scale features.
• Unknown sample size and geographic coverage specifics limit reproducibility assessments.
