MISR Level 1B2 Ellipsoid Data: Multi-angle Top-of-Atmosphere Radiance

Ongoing data collection from the NASA MISR instrument provides geometrically corrected, top-of-atmosphere radiance measurements. The instrument captures each surface location from 9 different angles and in 4 spectral wavelengths (blue, green, red, near-infrared). This data is produced by NASA to monitor long-term trends in aerosols, clouds, and land surface cover.

Use Cases

• Modeling atmospheric aerosol types and concentrations based on multi-angle spectral radiance.
• Classifying cloud types and estimating cloud heights using the nine camera angles.
• Analyzing land surface vegetation canopy structure from multi-spectral, multi-angle observations.
• Monitoring long-term environmental changes by leveraging the ongoing data collection.

Strengths

• Data is collected from 9 different viewing angles, providing stereoscopic and bidirectional reflectance information.
• Includes measurements in 4 distinct spectral bands (blue, green, red, near-infrared).
• Data is topographically and geometrically corrected, as processed by PGE22.

Limitations

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