Short summary
This study established a four-dimensional (hourly; 0.03° × 0.03° × 34 height layers) aircraft emission inventory dataset in the landing-and-takeoff cycle for China during 2019–2023 considering actual running time and flight trajectory. The dataset reflects unique horizontal and height spatial characteristics and hourly temporal variations of aircraft emissions and the impact of COVID-19 on these emissions, providing essential information for environmental analysis and policy decisions.
