全球2°×2.5°分辨率逐月大气二氧化碳浓度栅格模拟数据集（1992-2020年）

1992-2020年全球大气二氧化碳浓度2°×2.5°分辨率逐月栅格模拟数据集，包括1992-2020年全球逐月CO2浓度均值数据集，数据格式为nc格式。该数据集具有全球尺度、时序长、精度高等优点，可在一定程度上改进全球变化模拟中使用单一站点数值表征全球CO2浓度的不足，为地理学、生态学等学科相关研究提供数据支持。

Global monthly gridded simulation dataset of atmospheric carbon dioxide concentration with 2°×2.5° resolution from 1992 to 2020, which includes the global monthly mean CO2 concentration dataset from 1992 to 2020. The data is stored in netCDF (nc) format. This dataset has the advantages of global coverage, long time series and high accuracy. It can partially address the shortcomings of using single-site numerical values to characterize global CO2 concentration in global change simulations, and provide data support for relevant research in disciplines such as geography and ecology.
