Definition on NDVI curve and Physiological description

OnsetT

The NDVI value at the start of the growth, seedling

OnsetV

The time when Onset is achieved

MaxV

The maximum NDVI value in the season

MaxT

The time when the MaxV attained, anthesis growth stage

OffsetV

The NDVI value at the end of the season

OffsetT

The time when Offset attained, senescence growth stage

LengthGS

The length of growing season

BeforeMaxT

The length of time between Onset and MaxV

AfterMaxT

The length of time between MaxV and Offset

GreenUpSlope

The rate of increase in NDVI value between Onset and MaxV

BrownDownSlope

The rate of decrease in NDVI value between MaxV and Offset

TINDVI

The area under the NDVI curve between Onset and Offset

TINDVIBeforeMax

The area under the NDVI curve between Onset and MaxV

TINDVIAfterMax

The area under the NDVI curve between MaxV and Offset

Asymmetry
