VNP43D50: VIIRS M11 Valid Observation Quality for Global Albedo

Global satellite data provides a daily valid observation quality layer for the VIIRS M11 band, derived from a 16-day rolling window at 1,000-meter resolution. This product is part of the BRDF/Albedo Climate Modeling Grid suite designed for climate simulation models. The data are temporally weighted to the ninth day of the 16-day retrieval period.

Use Cases

• Assessing data quality for VIIRS M11 band retrievals in climate models based on the valid observation layer.
• Filtering albedo data for downstream products like VNP13 Vegetation Indices using the quality flags.
• Monitoring surface radiative properties over time using the daily, globally gridded Climate Modeling Grid product.

Strengths

• Cross-platform presence on NASA Earthdata and Data.gov signals established importance and reliability.
• Algorithm improvements include enhanced calibration coefficients for the entire Suomi NPP mission and corrected geolocation accuracy.
• Provides a specific quality layer for a single spectral band (M11), supporting detailed sensor-specific analysis.

Limitations

• Key metadata such as row count, column names, and file size are unknown across all sources.
• The dataset's temporal coverage and specific update frequency beyond 'daily' are not explicitly stated.
• Relies on a 16-day composite, which may smooth over rapid surface changes.
