Daily Global Satellite Radiance Summary at 0.5-Degree Resolution

A daily statistical summary of top-of-atmosphere radiance parameters, gridded at a 0.5 by 0.5-degree geographic resolution. The data is produced by NASA's Multi-angle Imaging SpectroRadiometer (MISR) instrument, which collects ongoing measurements from nine cameras at four spectral bands. It provides a global overview of Bidirectional Reflectance Factors and spectral expansive albedos for atmospheric and surface analysis.

Use Cases

• Model aerosol optical depth and type using the statistical summary of spectral Bidirectional Reflectance Factors from the four spectral bands (443, 555, 670, 865 nm).
• Classify cloud types and heights by analyzing the multi-angle radiance data from the nine cameras at view angles of 0, 26.1, 45.6, 60.0, and 70.5 degrees.
• Monitor trends in land surface vegetation cover and canopy structure using the near-infrared (865 nm) band reflectance and albedo statistics.
• Study the angular dependence of surface reflectance for different sub-region classifications provided in the daily statistical overview.

Strengths

• Global spatial coverage achieved within a nine-day repeat cycle.
• Multi-angle observations from nine cameras across four distinct spectral bands.
• Data reported on a consistent 0.5 by 0.5-degree geographic grid.

Limitations

• Specific row count, sample size, and temporal range are not provided in the description.
• Data is a daily statistical summary, which may lack the granularity of higher-frequency Level 1 or Level 2 products.
• The 0.5-degree resolution may be too coarse for regional or local-scale analysis.
