It is calculated by dividing the difference in technical albedos between measurements in the near infrared and visible red part of the spectrum by the sum of both measurements. This value provides important information about the "greenness" and density of vegetation. Weekly and monthly thematic synthesis products are also derived from this daily operational product, at each step becoming successively free of clouds.

These level 1 data are used for generating RGB - quicklooks overlayed with coastline and a so called media product which is a subset showing wide parts of Central Europe (“Central Europe”). The level 1 data are also used for generating value-added products such as the “Normalised Difference Vegetation Index” of Europe, the sea surface temperature of European seas and the land surface temperature of Europe representing a day-time or nighttime land surface temperature. For all value-added products different routines as e.g. cloud masking, georeferencing, including land-sea mask and compositing are necessary (level 2 data). The level 2 data are used for deriving daily, weekly and monthly level 3 products which are accessible by the internet (http://eoweb.dlr.de) Further information is available at http://wdc.dlr.de/sensors/avhrr/
