Wheat Phenology Extraction from Time-Series of SPOT/VEGETATION Data

Vegetation phenological dynamics is an indicator of plant response to climate regime. Various methodologies are developed to determine the timing of vegetation greenup and senescence using time series of remote sensing data, but most of them are used for forests. This paper presented a simple phenology model to identify wheat (Triticum aestivum L.) greenup onset date from SPOT/VEGETATION data. An experiment is performed for a wheat field in the North China plain.
