Flowering phenology observations from 23 Arctic and alpine sites from 1992 th...
Advancing phenology is one of the most visible effects of climate change on plant communities, and has been especially pronounced in temperature-limited tundra ecosystems.... -
Long-term phenology data for 47 tundra plant species at 19 high-latitude site...
Warmer temperatures are accelerating the phenology of organisms around the world. Temperature sensitivity of phenology might be greater in colder, higher-latitude sites than in... -
Circumpolar vegetation dynamics and phenology (CVD) product (1999-present)
Land surface phenology (LSP) and vegetation growth of the circumpolar north are changing in response to more pronounced warming in the region. We here provide phenology index... -
