Description

The Ocean Biology DAAC produces near real-time (NRT) products using the best-available combination of ancillary data from meteorological and ozone data. As such, the inputs and the calibration used are less than optimal. Near real-time products provide a snapshot of the data during a short time period within a single orbit.

LANDVI suite provides vegetation and land-surface indices derived from surface reflectance. Six of the indices are heritage, and four are hyperspectral-enabled. Users should see documentation for more details. Users should also note that the L3M product is masked for clouds.

 Geophysical variables in this suite include:
  • ndvi — Normalized Difference Vegetation Index (unitless) 
  • evi — Enhanced Vegetation Index (unitless)
  • cire — Chlorophyll Index Red Edge (unitless)
  • pri — Photochemical Reflectance Index (unitless)
  • car — Carotenoid Content Index (unitless)
  • cci — Chlorophyll?~@~SCarotenoid Index (unitless)
  • mari — Anthocyanin Reflectance Index (unitless)
  • ndii — Normalized Difference Infrared Index (unitless)
  • ndwi — Normalized Difference Water Index (unitless)
  • ndsi — Normalized Difference Snow Index (unitless)

• l2_flags — Level-2 Processing Flags (bitmask; see product attributes for flag definitions)
