Data from: Drivers of contemporary and future changes in Arctic seasonal transition dates for a tundra site in coastal Greenland

Climate change has had a significant impact on the seasonal transition
dates of Arctic tundra ecosystems, causing diverse variations between
distinct land surface classes. However, the combined effect of multiple
controls as well as their individual effects on these dates remains
unclear at various scales and across diverse land surface classes. Here we
quantified spatiotemporal variations of three seasonal transition dates
(start of spring, maximum Normalized Difference Vegetation Index (NDVImax)
day, end of fall) for five dominant land surface classes in the ice-free
Greenland and analyzed their drivers for current and future climate
scenarios, respectively.
