Soil-driven dry-hot events cause deeper GPP loss (−1.115 g·C·m−2·day−1) and slower recovery (+2.238 days).
Impacts of soil moisture deficits intensify over time, widening divergence from atmospheric-driven events.
Soil moisture control strengthens with event severity, aridity, and future warming scenarios.
