- Observation Three temperature indices increased across six winegrape regions in the later period.
- Observation First fall frost was delayed by 0–16 days in five of six regions.
- Method / resource The original GSR model yielded biased harvest-date predictions.
- Method / resource Recalibrated GSR model calibration performance reached R2 0.83 and NRMSE 2.8%.
- Observation Simulated harvest dates advanced by 6–30 days across six varieties and regions in P2.
- Observation Freezing injury index decreased 2–60% in P2 across all regions.
- Association The magnitude of freezing injury reduction depended on elevation.
