VIIRS/NPP Surface Reflectance Daily Global 0.05 Deg Climate Grid

VIIRS/NPP Surface Reflectance Daily L3 Global 0.05 Deg CMG V001 provides daily estimates of land surface reflectance from the Suomi NPP satellite. The data product includes twelve reflectance bands and five brightness temperature bands, corrected for atmospheric gases and aerosols, at a 0.05-degree resolution. This Version 1 product was decommissioned by NASA on April 8th, 2025, with users directed to newer Version 2 data.

Use Cases

• Modeling land surface albedo for climate simulations based on the 0.05-degree Climate Modeling Grid format
• Analyzing daily surface reflectance trends using the twelve imagery and moderate resolution bands
• Studying atmospheric aerosol impacts on surface observations based on the described correction processes
• Assessing data quality for downstream vegetation and albedo products using the included information layers

Strengths

• Data is corrected for atmospheric conditions including molecular gases and aerosols
• Provides data for twelve reflectance bands and five brightness temperature bands
• Includes auxiliary information layers for angles, quality, time of day, and number mapping

Limitations

• This Version 1 product was officially decommissioned on April 8th, 2025
• Known issues include potential incorrect 'High Aerosol' flagging over bright surfaces
• Column-level documentation is absent; field semantics must be inferred after download
