VNP43D49: VIIRS Band M10 Valid Observation Quality for Global Climate Models

Daily global data layers are produced using a 16-day rolling window, temporally weighted to the ninth day. The VNP43D49 product provides the valid observation quality layer for VIIRS band M10 at a 30 arc-second (1,000 meter) resolution on a Climate Modeling Grid. It is part of a suite supporting BRDF and albedo retrievals for climate simulation models.

Use Cases

• Assessing data quality for BRDF/albedo retrievals based on the valid observation layer for band M10.
• Inputting validated surface reflectance data into climate simulation models using the global Climate Modeling Grid.
• Monitoring temporal changes in land surface properties using the daily, 16-day composite product.
• Cross-validating downstream products like VNP13 Vegetation Indices that rely on corrected aerosol flags from this data lineage.

Strengths

• Provides global coverage on a Climate Modeling Grid designed for climate simulations.
• Incorporates algorithm improvements including better calibration coefficients for the entire Suomi NPP mission and corrected geolocation.
• Cross-platform presence on NASA Earthdata and Data.gov signals its importance and curation within official data archives.

Limitations

• Specific column names and data layer structure are not detailed in the provided metadata.
• Metadata completeness varies across platforms, with some lacking license, author, or size information.
• Relies on a 16-day composite, which may smooth over very short-term surface changes.
