ABoVE: Annual Phenology Derived from Landsat across the ABoVE Core Domain, 1984-2014 : Arctic-Boreal Vulnerability Experiment (ABoVE)
This dataset provides annual maps of the timing of spring onset with leaf emergence, of autumn onset with leaf senescence, and of peak greenness for each 30 m pixel derived from Landsat time series of Thematic Mapper (TM) and Enhanced Thematic Mapper (ETM+) observations from 1984 to 2014. The ABoVE...
