Exact excerpt

The study used eddy-covariance carbon flux data, satellite-derived gross primary productivity and solar-induced chlorophyll fluorescence across the Northern Hemisphere, plus multi-year frost manipulative experiments. Its figure materials include five datasets—flux tower, CSIF, FluxSat-GPP, GLASS-GPP and GOSIF-GPP—analyzed at frost thresholds of −1, −3 and −5 °C. Temporal trends were analyzed from 2001 to 2020, while manipulative frost experiments covered 2018 to 2024 and confirmed overcompensation in grasslands.
