2. Introduction
The following global images were taken from AVHRR (1980 to 2000) and MODIS (2000 to 2010) phenology metrics.
Phenology metrics
Start of the season (SOS)
Length of the season (LOS)
End of the season (EOS)

3. Objective
To determine areas where phenology metrics derived from NDVI and EVI2 differ from each other.

10. Conclusions
This table shows whether NDVI differs or not from EVI2 (i.e. NDVI (<, > or =) EVI2)
