Abstract

En 中文

• Integrated phenology, taxa, and XGBoost with 15-year pollen data in Beijing. • Developed N-PEPM combining thermal thresholds and phenological probabilities. • Implemented WRF-Chem-Pollen for hourly spatiotemporal pollen simulations. • Revealed stage-specific pollen effects and “early promotion-late suppression.”.
