VNP43D75: VIIRS White-Sky Albedo for Band M11

VNP43D75 Version 1 is a decommissioned NASA/NOAA Suomi NPP VIIRS data product providing daily white-sky albedo measurements for the M11 (2.25 μm) spectral band. It is generated at a 30 arc-second (1,000 meter) resolution using a 16-day temporal composite, weighted to the ninth day, and formatted on a global Climate Modeling Grid. The dataset is part of a broader BRDF/Albedo product suite designed for climate simulation models.

Use Cases

• Modeling surface energy balance in climate simulations based on the global Climate Modeling Grid (CMG) format.
• Analyzing temporal trends in land surface albedo using the daily, 16-day composite data.
• Studying the reflectance properties of specific land cover types using the 2.25 μm (M11) spectral band data.

Strengths

• Provides global spatial coverage on a standardized Climate Modeling Grid.
• Offers a specific, high-resolution (30 arc-second) measurement for a key spectral band (M11).

Limitations

• The dataset is explicitly decommissioned (as of July 31, 2025), directing users to newer Version 2 products.
• Metadata for key attributes like row count, file size, and specific columns is missing or listed as unknown across all sources.
• The description notes a known issue with an abnormally high activation of a high aerosol flag in Collection 1 data.
