Phenological divergence between early- and late-successional tree species is amplified by artificial light at night and temperature

This dataset supports the article titled “Phenological divergence between early- and late-successional tree species is amplified by artificial light at night and temperature.” The dataset includes two main components. The Site_data_original.zip contains the original site-level phenological observations together with the corresponding artificial light at night (ALAN; DMSP-VIIRS) and temperature data (E-OBS). The Site_data_secondary.zip contains site-level summaries, including mean phenological and climatic conditions as well as their temporal trends.
