VNP43D48: Daily VIIRS Band M8 Valid Observation Quality for Global Climate Models

Daily global data layers provide the valid observation quality for VIIRS band M8, synthesized from 16 days of observations at a 30 arc-second (1,000 meter) resolution and temporally weighted to the ninth day. This dataset is part of a Climate Modeling Grid (CMG) product suite designed for climate simulation models, containing a single layer representing the quality of observations over the retrieval period. It is produced by NASA/NOAA from the Suomi NPP satellite's Visible Infrared Imaging Radiometer Suite (VIIRS).

Use Cases

• Assessing data quality for land surface albedo retrievals based on the valid observation quality layer for band M8.
• Inputting validated observation counts into climate simulation models based on the Climate Modeling Grid (CMG) format.
• Monitoring temporal consistency in surface reflectance using the 16-day rolling composite methodology.
• Integrating with other VNP43D series products (e.g., BRDF/Albedo Quality, Snow Status) for comprehensive land surface analysis.

Strengths

• Provides daily, global coverage at a consistent 30 arc-second (1,000m) resolution.
• Uses a 16-day composite methodology to improve data reliability, with temporal weighting to a central day.
• Specifically formatted as a Climate Modeling Grid (CMG) for direct use in climate simulation models.

Limitations

• Column names and specific data structure are not provided in the available metadata.
• Dataset size, row counts, and detailed sample counts are unknown across all sources.
• Author information is inconsistently reported (LPCLOUD on one platform, null on others).
