MISR Level 2 FIRSTLOOK Aerosol parameters V002

MISR Level 2 FIRSTLOOK Aerosol parameters version 2 contains aerosol optical depth, particle type, and associated atmospheric data. The dataset is produced by NASA's Multi-angle Imaging SpectroRadiometer instrument, which uses nine cameras at four spectral bands to view Earth from different angles. Data collection for this product is ongoing, with global coverage achieved in nine days.

Use Cases

• Monitor global trends in aerosol optical properties based on multi-angle imagery and spectral band measurements.
• Measure aerosol forcing of the shortwave planetary radiation budget based on aerosol optical depth and surface albedo data.
• Distinguish different aerosol particle types based on compositional model identifiers and retrieval residuals.
• Analyze seasonal and long-term trends in atmospheric particles based on the ongoing data collection.

Strengths

• Data is collected from nine cameras at four spectral bands (443, 555, 670, 865 nm) and five view angles (0, 26.1, 45.6, 60.0, 70.5 degrees).
• Provides global coverage with a revisit time of nine days.
• Contains multiple aerosol and atmospheric parameters, including optical depth, particle type, relative humidity, and ozone optical depth.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
