MODIS/Terra Gross Primary Productivity: 8-Day Global 500m Grid

MODIS/Terra Gross Primary Productivity (GPP) Version 6.1 is a cumulative 8-day composite data product with 500-meter pixel resolution. It is produced by the National Aeronautics and Space Administration (NASA) and provides information on GPP and Net Photosynthesis (PSN) for modeling terrestrial energy, carbon, and water cycles. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling terrestrial carbon cycle processes based on Gross Primary Productivity (GPP) values.
• Calculating vegetation energy and water cycles based on the radiation use efficiency concept.
• Analyzing Net Photosynthesis (PSN) by subtracting Maintenance Respiration (MR) from GPP.
• Assessing data quality for ecological models using the provided Quality Control (QC) layer.

Strengths

• Data is produced by the National Aeronautics and Space Administration, an authoritative source.
• Product is at Version 6.1, incorporating calibration and polarization corrections from previous versions.
• Includes a dedicated Quality Control (QC) layer for both GPP and PSN data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
