Tmax dataset for "Cumulative Heatwaves Accelerated Ozone Buildup in China" (You et al. 2025)

Daily maximum temperature data were sourced from the CN05.1 climate dataset. The dataset offers a spatial resolution at 0.25° and includes daily observational data from over 2,400 meteorological stations across China (Wu & Gao, 2013; Xu et al., 2009). Wu, J., & Gao, X.
