Remote sensing phenology of two Chinese northern Sphagnum bogs under climate drivers during 2001 and 2018

Boreal peatlands, of which Sphagnum bogs are one of the main types, play essential roles in the terrestrial soil carbon pool. Vegetation phenology is a sensitive indicator that reveals the underlying processes as well as responses to climate change, while currently there remain knowledge gaps in exp...
