Monthly Global Aerosol Optical Thickness from ADEOS-II Satellite

Aerosol optical thickness measurements at 0.5 microns derived from the GLI sensor onboard the ADEOS-II satellite. Japan Aerospace Exploration Agency (JAXA) produced this Level 3 binned product, which aggregates data into monthly global maps at a 1/4-degree spatial resolution. The dataset version is 2, with the last recorded update in October 2003.

Use Cases

• Modeling global aerosol transport patterns using the monthly binned aerosol optical thickness values.
• Analyzing seasonal trends in atmospheric particulates from the 1-month statistical period data.
• Calibrating other satellite aerosol products using the 678nm and 865nm channel inputs specified for retrieval.
• Studying surface reflectance corrections that incorporate ancillary wind, ozone, and water vapor data mentioned in the algorithm.

Strengths

• Global spatial coverage with a consistent 1/4-degree grid.
• Data includes statistical aggregates (sum, square sum, max, min) for each binned pixel.
• Product is based on a defined retrieval algorithm using specific visible and near-IR channels.

Limitations

• Temporal coverage is limited, with the last update in 2003, making it a historical snapshot.
• The spatial resolution of 1/4 degree is coarse for regional or local-scale analysis.
• Specific row counts, sample sizes, and validation metrics are not provided.
