Scientists studying the Qinghai-Tibet Plateau found that land surface temperature—measured by satellite—better predicts when plant growing seasons end than traditional weather station data, and that the season's end date, not its start, is the main driver of how long plants grow each year.
From 2001 to 2020, the end of the growing season showed a significant positive correlation with land surface temperature—warmer surfaces linked to later seasonal shutdowns.
The length of the growing season is primarily controlled by when the season ends (autumn), not when it begins (spring).
Satellite-derived variables (land surface temperature, effective moisture, surface albedo) explained vegetation timing changes better than traditional air temperature and precipitation records.
