NOAA-14 AVHRR: Daily Global Surface Reflectance at 0.05 Degree Resolution

A daily global land surface climate data record generated by the Long-Term Data Record (LTDR) project. The dataset provides atmospherically corrected surface reflectance from the NOAA-14 satellite's AVHRR instrument, bridging data from NOAA, MODIS, and VIIRS missions. It is produced and distributed by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling long-term climate change impacts based on the fundamental climate data record (FCDR) of surface reflectance.
• Monitoring vegetation health and trends using derived Normalized Differential Vegetation Index (NDVI) data.
• Analyzing land surface radiative properties based on BRDF-corrected reflectance for bands 1, 2, and 3.
• Studying surface energy balance using included thermal data from bands 3, 4, and 5.

Strengths

• Part of a validated Long-Term Data Record (LTDR) project designed for studying global climate change.
• Integrates data from eight AVHRR missions, including NOAA-7 through NOAA-19 and MetOp-B, creating a historical bridge.
• Provides multiple derived products, including daily surface reflectance, NDVI, and an experimental LAI/fPAR product.

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.
