MISR Level 3: Daily Global Radiance and Albedo Summary at 0.5° Resolution

A daily statistical summary of Multi-angle Imaging SpectroRadiometer (MISR) data, reported on a 0.5-degree by 0.5-degree geographic grid. The product contains spectral top-of-atmosphere Bidirectional Reflectance Factors and spectral expansive albedos, derived from nine cameras measuring in four spectral bands (443, 555, 670, and 865 nm). Data collection is ongoing, produced by the National Aeronautics and Space Administration, with a last update recorded for March 13, -2026.

Use Cases

• Monitoring atmospheric aerosol amounts and types based on multi-angle spectral radiance data.
• Analyzing cloud properties, types, and heights using the statistical overview of spectral albedos.
• Tracking land surface cover and vegetation canopy structure trends from the global radiance summary.
• Studying the bidirectional reflectance distribution function (BRDF) for various surface and sky classifications.

Strengths

• Data is collected from nine cameras at distinct view angles (0, 26.1, 45.6, 60.0, and 70.5 degrees), providing multi-perspective observations.
• Provides measurements in four specific spectral bands centered at 443, 555, 670, and 865 nanometers.
• Offers global coverage, achieved in a nine-day repeat cycle, with a consistent spatial resolution of 0.5 degrees.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The description metadata is limited; actual data quality and structure require manual inspection after download.
