VNP43D80: VIIRS/NPP Nadir Reflectance for Band M1

Global daily Nadir BRDF-Adjusted Reflectance (NBAR) data for the VIIRS satellite's M1 band (0.412 μm) is produced at 30 arc-second (1,000 meter) resolution. The dataset uses a 16-day temporal composite weighted to the ninth day and is formatted in a Climate Modeling Grid for global climate simulations. It is part of a product suite providing NBAR values for nine moderate resolution bands and the Day/Night Band.

Use Cases

• Climate simulation modeling based on the global Climate Modeling Grid (CMG) coverage.
• Analyzing surface reflectance trends using the daily, nadir-adjusted NBAR values.
• Studying land surface radiative properties from the VIIRS M1 band (0.412 μm) data.
• Cross-comparing reflectance across multiple VIIRS bands using the broader VNP43D product suite.

Strengths

• Provides global coverage at a consistent 30 arc-second (1,000 meter) resolution.
• Uses a sophisticated algorithm to remove view angle effects, modeling reflectance at nadir view and local solar noon.
• Includes improvements such as better calibration coefficients and corrected geolocation accuracy.

Limitations

• Specific column names and dataset size (rows, file size) are not provided by any source.
• Each product file contains only one data layer, which may limit simultaneous analysis of multiple bands.
• Known issues exist, requiring users to consult an external assessment website for complete details.
