NOAA-16 AVHRR: Daily Global Surface Reflectance at 0.05 Degree Resolution

NOAA-16 AVHRR Atmospherically Corrected Surface Reflectance Daily L3 Global 0.05 Deg. CMG is a satellite-derived land surface climate data record produced by NASA's Long-Term Data Record project. The dataset includes BRDF-corrected surface reflectance for three spectral bands, quality flags, solar/view angles, and thermal data, processed into a daily global grid. It was last updated on March 12, 2026.

Use Cases

• Monitoring global vegetation health based on the derived Normalized Differential Vegetation Index (NDVI).
• Analyzing land surface radiative properties based on atmospherically corrected surface reflectance.
• Studying climate change impacts using the long-term, cross-mission data record.
• Modeling leaf-area index and fraction of absorbed photosynthetically active radiation (LAI/fPAR) as an experimental product.

Strengths

• Part of a long-term climate data record (CDR) bridging data from multiple satellite missions, including NOAA AVHRR and MODIS.
• Provides daily global coverage at a 0.05-degree spatial resolution.
• Includes multiple data layers: surface reflectance for three bands, quality flags, angles, and thermal data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analyses.
