Comment:
One of the reported changes in arctic and boreal ecosystems in response to warming climate is the advance of the leaf and flower appearance in spring. We developed a remote sensing (RS) method, using 1km spatial resolution SPOT-VGT sensor, to estimate the date of boreal ecosystem green-up without detrimental effect of snow on the signal.
The tif file is made of 15 images, one for each year from 1998 to 2012. The pixel value gives the date at which the ecosystem starts green-up (expressed as the day of year) as estimated in Delbart et al. 2005.
