Sentinel-2 Daily Global Vegetation Indices at 30-Meter Resolution

Vegetation index data derived from the Sentinel-2 Multi-Spectral Instrument, providing nine daily indicators of vegetation health. The Harmonized Landsat and Sentinel-2 project, funded by NASA's SNWG and operated by LPCLOUD, combines measurements from Sentinel-2A, 2B, and 2C satellites for global land observations every 1.6 days.

Use Cases

• Tracking vegetation changes over time using daily NDVI and EVI values.
• Identifying areas of drought stress or deforestation via the NDMI and NBR indices.
• Assessing agricultural crop health and phenology with SAVI and MSAVI metrics.
• Monitoring post-fire recovery and burn severity using NBR and NBR2 bands.
• Analyzing canopy water content and moisture levels with NDWI and TVI data.

Strengths

• Provides nine distinct vegetation indices (NDVI, EVI, SAVI, MSAVI, NDMI, NDWI, NBR, NBR2, TVI) for detailed analysis.
• Global coverage with a high revisit frequency of observations every 1.6 days.
• Data is gridded to a consistent 30-meter spatial resolution and MGRS tiling system for stackable time-series analysis.

Limitations

• Specific temporal coverage, total data volume, and row counts are not provided in the description.
• Data is limited to vegetation indices derived from Sentinel-2; raw spectral bands or Landsat data are separate products.
