MISR OBC Data V002: On-board Calibrator Radiometry for Nine Cameras

MI1AOBC_2 is the Multi-angle Imaging SpectroRadiometer On-board Calibrator Data version 2 from NASA. It contains radiometry from PIN and HQE diodes and goniometer mechanism readings collected during calibration operations near the poles and over Earth's dark side. The instrument consists of nine push-broom cameras measuring radiance in four spectral bands centered at 443, 555, 670, and 865 nm.

Use Cases

• Calibrating satellite sensor readings based on diffuser panel brightness data collected near the poles.
• Analyzing multi-angle reflectance characteristics based on data from nine cameras at view angles of 0, 26.1, 45.6, 60.0, and 70.5 degrees.
• Modeling spectral band response based on Gaussian-shaped bands centered at 443, 555, 670, and 865 nm.
• Monitoring instrument performance over time using radiometry from PIN and HQE diodes.

Strengths

• Data is provided by the authoritative source, the National Aeronautics and Space Administration (NASA).
• Description specifies instrument details, including nine cameras, four spectral bands, and five view angles.
• Data is updated as of 2026 03 13 00:37:12.803805.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data files are in specialized formats (BIN, ISO, PDF, HTML, KML), which may require specific tools to process.
