An Enhanced TIMESAT Algorithm for Estimating Vegetation Phenology Metrics From MODIS Data
2011
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
An enhanced TIMESAT algorithm was developed for retrieving vegetation phenology metrics from 250 m and 500 m spatial resolution Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation indexes (VI) over North America. MODIS VI data were pre-processed using snow-cover and land surface temperature data, and temporally smoothed with the enhanced TIMESAT algorithm. An objective third derivative test was applied to define key phenology dates and retrieve a set of phenology metrics. This
