CAR INTEXB BRDF Measurements: Bidirectional Reflectance from Atmospheric Pollution Study

CAR INTEXB BRDF Measurements L1 V2 (CAR_INTEXB_BRDF) is a NASA dataset from the Intercontinental Chemical Transport Experiment-Phase B (INTEX-B). The data set consists of observations made with the CAR instrument, providing values for bidirectional reflectance factor at varying spectral bands. INTEX-B was conducted in two phases: March 2006 in Mexico and April-May 2006 over the western Pacific, focusing on pollution transport and atmospheric photochemistry.

Use Cases

• Modeling aerosol radiative forcing based on bidirectional reflectance factor measurements.
• Analyzing spectral reflectance properties of atmospheric pollution plumes over oceans.
• Studying the impact of Asian city pollution outflow on regional radiation budgets.
• Validating satellite-derived atmospheric reflectance products with in-situ CAR instrument data.

Strengths

• Data originates from a NASA mission (INTEX-B) with a defined scientific focus on pollution transport.
• Provides bidirectional reflectance factor values, a key parameter for radiation studies.
• Covers two distinct geographic and temporal phases: Mexico (March 2006) and the western Pacific (April-May 2006).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files include non-standard formats (BIN, ISO) which may require specialized tools to process.
