VNP43D74: VIIRS/NPP White-Sky Albedo for Band M10 Daily Global Climate Grid

Daily global data from the Suomi NPP VIIRS satellite provides white-sky albedo values for the 1.61 μm (M10) band at a 30 arc-second (1,000 meter) resolution. Each daily value is produced using a 16-day data window, temporally weighted to the ninth day, and formatted for use in climate simulation models on a global Climate Modeling Grid. This product is part of a larger BRDF/Albedo suite and was decommissioned in July 2025, with users directed to newer Version 2 data products.

Use Cases

• Parameterizing land surface albedo in climate simulation models based on the Climate Modeling Grid format.
• Analyzing temporal trends in surface reflectance for the 1.61 μm shortwave infrared band.
• Studying surface radiative properties and anisotropy as part of the broader VIIRS BRDF/Albedo product suite.

Strengths

• Provides global spatial coverage on a standardized Climate Modeling Grid (CMG).
• Offers daily temporal resolution synthesized from a 16-day observation window.
• Data is produced by the authoritative NASA/NOAA Suomi NPP mission.

Limitations

• This specific Version 1 dataset was decommissioned on July 31, 2025, limiting its utility for current analysis.
• Metadata on specific data columns, row counts, and file sizes is unavailable across all sources.
• The description notes a known issue with an abnormally high activation of a high aerosol flag in Collection 1 data.
