NOAA-07 AVHRR: Daily Global Surface Reflectance at 0.05 Degree Resolution

NOAA-07 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 provides daily, atmospherically and BRDF-corrected surface reflectance for three spectral bands, along with quality flags, solar/view angles, and thermal data. It is part of a long-term record bridging data from multiple polar-orbiting satellite missions to support climate change studies.

Use Cases

• Modeling long-term vegetation trends based on the derived NDVI thematic climate data record.
• Studying surface radiative properties and albedo changes using atmospherically corrected reflectance bands.
• Analyzing land surface phenology and productivity cycles based on daily LAI/fPAR experimental product.
• Calibrating and validating climate models using a consistent, multi-mission satellite data record.

Strengths

• Part of a validated Long-Term Data Record (LTDR) project designed for climate change studies.
• Provides daily global coverage at a 0.05-degree spatial resolution.
• Includes data from eight AVHRR missions, creating a multi-decade bridge to MODIS and VIIRS data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is available in HDF4 format, which may require specialized tools for processing.
