This dataset contains in-situ measured and simulated surface oxygen concentration data over the Qinghai-Tibet Plateau. Specifically, the in-situ measured surface oxygen concentration data were obtained through field surveys, including oxygen concentration data from 807 measurement sites acquired on the Qinghai-Tibet Plateau between 2017 and 2022, alongside corresponding geospatial and environmental parameters such as latitude and longitude, elevation, air temperature, relative humidity, atmospheric pressure, vegetation coverage, landform types, and vegetation types. The simulated surface oxygen concentration data were generated via model simulation, covering annual mean oxygen concentration distribution data, January mean oxygen concentration distribution data, July mean oxygen concentration distribution data, and the difference data between July and January oxygen concentrations over the plateau. All simulated datasets have a spatial resolution of 1 km × 1 km and are expressed in percent (%). Cross-validation analysis demonstrates that the surface oxygen concentration simulation model for the Qinghai-Tibet Plateau is relatively robust, with high simulation accuracy. This dataset fills the research gap in oxygen concentration data measurement and related studies over the Qinghai-Tibet Plateau, providing essential data support for analyzing the influencing factors of surface oxygen concentration and investigating its spatiotemporal characteristics across the plateau. It is of great significance for promoting the construction of ecological civilization in the Qinghai-Tibet Plateau region.
