METOP-B AVHRR Top-of-Atmosphere Reflectance Daily Global 0.05 Deg

The Long-Term Data Record (LTDR) project draws from eight AVHRR missions, including NOAA-7 through NOAA-19 and MetOp-B. It generates a daily surface reflectance product as a fundamental climate data record, along with derived NDVI and LAI/fPAR thematic products. This specific dataset, M1_AVH02C1, provides daily top-of-atmosphere reflectance at a 0.05-degree resolution.

Use Cases

• Studying global climate change trends based on long-term satellite reflectance data.
• Monitoring vegetation health and dynamics based on derived NDVI and LAI/fPAR thematic products.
• Analyzing land surface radiative properties based on top-of-atmosphere reflectance for bands 1 and 2.
• Validating and bridging data between different satellite missions (AVHRR, MODIS, VIIRS) based on the LTDR project's unique role.

Strengths

• The LTDR project serves as a bridge connecting data from eight distinct AVHRR missions and other major satellite programs.
• Produces daily surface reflectance, NDVI, and LAI/fPAR products for long-term climate studies.
• Data is generated at a global 0.05-degree resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The LAI/fPAR thematic product was developed as an experimental product.
