MISR Geometric Parameters V003: Sun and View Angles from Multi-angle Satellite Imagery

MISR Geometric Parameters Version 3 contains sun and view angle measurements at the Earth's reference ellipsoid from the Multi-angle Imaging SpectroRadiometer instrument. The instrument views Earth with 9 cameras pointed in different directions, capturing each surface point in 4 wavelengths (blue, green, red, near-infrared). Data collection is ongoing and the product is distributed by NASA in NetCDF-4 format.

Use Cases

• Model atmospheric aerosol effects based on multi-angle sun and view geometry data.
• Classify cloud types and heights based on angular reflectance patterns.
• Analyze land surface and vegetation canopy structure using multi-spectral, multi-angle observations.
• Calibrate other satellite or ground-based remote sensing data using the geometric reference parameters.

Strengths

• Data collection is explicitly stated as ongoing, suggesting continuous updates.
• Product format migrated to NetCDF-4, which is a modern, self-describing data format.
• Instrument captures data from 9 distinct view angles and 4 spectral wavelengths.

Limitations

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