VNP43D75: VIIRS White-Sky Albedo for Band M11 Daily Global Climate Grid

NASA/NOAA Suomi NPP VIIRS VNP43D75 provides daily white-sky albedo (WSA) for the M11 band (2.25 μm) on a global Climate Modeling Grid (CMG). The product is generated daily using a 16-day data composite, temporally weighted to the ninth day, at a 30 arc-second (approximately 1,000 meter) spatial resolution. It is part of a larger BRDF/Albedo product suite designed for use in climate simulation models.

Use Cases

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

Strengths

• Provides global coverage on a standardized Climate Modeling Grid (CMG) for direct use in climate models.
• Offers daily temporal resolution using a 16-day composite to mitigate data gaps, with a stated spatial resolution of 30 arc-seconds (~1km).
• Cross-platform presence on NASA Earthdata and Data.gov signals its importance and official status as a core remote sensing product.

Limitations

• Metadata for specific column names, row counts, and file sizes is consistently missing across all source platforms.
• The dataset contains only a single data layer (WSA for band M11), requiring combination with other products for a full spectral analysis.
• Known issues exist, requiring users to consult an external website for complete quality assessment information.
