A dataset of carbon and water fluxes of the forest ecosystem at Beijing Olympic Forest Park Station from 2012 to 2020

This dataset is the flux observation data of the forest ecosystem at Beijing Olympic Forest Park Station from 2012 to 2020. The raw data collection site is located in Beijing Olympic Forest Park. Based on the ChinaFLUX data processing specifications, the raw observation data were processed to produce this standardized dataset of ecosystem carbon and water fluxes and key meteorological elements. In the dataset, the annual data includes 8 Excel data files, divided into two categories: LITE, which includes major fluxes and meteorological variables, and ALL, which adds data quality and interpolation indicators on the basis of LITE. Each category has four data files, including data files at four scales: half-hour (HH), day (DD), month (MM), and year (YY). This dataset is of great significance for accurately evaluating the position and role of carbon water flux in urban green space ecosystems in regional and global carbon water cycles.
