MODIS/Terra Vegetation Indices 16-Day L3 Global 0.05Deg CMG V004Entry ID: MOD13C14
Abstract: Decommissioned product.
Global MODIS vegetation indices are designed to provide consistent spatial and temporal comparisons of vegetation conditions. Blue, red, and near-infrared reflectances, centered at 470-nanometers, 648-nanometers, and 848-nanometers, respectively, are used to determine the MODIS daily vegetation indices.
The MODIS Normalized Difference Vegetation Index (NDVI) complements ... NOAA's Advanced Very High Resolution Radiometer (AVHRR) NDVI products and provides continuity for historical applications. The MODIS NDVI product contains atmospherically corrected bi-directional surface reflectances masked for water, clouds, and cloud shadows. Another MODIS index, the Enhanced Vegetation Index or EVI, uses the blue band to remove residual atmospheric contamination caused by smoke and sub-pixel thin cirrus clouds. The EVI also uses feedback adjustment to minimize canopy background variations and to enhance vegetation sensitivity from sparse to dense vegetation conditions.
Global MOD13C1 data are cloud-free spatial composites of the gridded 16-day 1-kilometer MOD13A2, and are provided as a level-3 product projected on a 0.05 degree (5600-meter) geographic Climate Modeling Grid (CMG). Cloud-free global coverage is achieved by replacing clouds with the historical MODIS time series climatology record.
Vegetation indices are used for globally monitoring vegetation conditions and are used in products displaying land cover and land cover changes. These data may be used as input for modeling global biogeochemical and hydrologic processes and global and regional climate. These data also may be used for characterizing land surface biophysical properties, including land cover.
