Description

Chuying Guo and four co-authors compare three ways of reading the seasons of plant life in two Chinese ecosystems, and find the methods disagree. Their study came out in 2025. Satellite greenness, carbon dioxide uptake, and direct ground observation each claim to mark when the growing season starts and ends.

One site was an alpine shrub meadow on the Tibetan plateau, the other a mixed forest in the northeast. Both remote methods put the season's start earlier and its end later than ground observers did, stretching the season. Warm springs advanced the start in both records. The forest site showed bigger disagreement than the meadow, likely from its complex mix of species. Of five extraction techniques tested, a dynamic threshold method agreed best across data types.
