Slide2Introduction
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)
Slide3Objective
To determine areas where phenology metrics derived from NDVI and EVI2 differ from each other.
