A dataset of carbon and water fluxes of the cropland ecosystem at Hulunbuir site from 2019 to 2020

The raw observation data collected using the eddy covariance method at the Hulunbuir cropland ecosystem flux observation site from 2019 to 2020 were processed based on the ChinaFLUX data processing specifications to produce this standardized dataset of ecosystem carbon and water fluxes and key meteorological elements. The site was established by Shanxi University. In this 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).
