A dataset of carbon and water fluxes at the Changling cornfield flux observation site from 2019 to 2020

The raw observation data acquired by the eddy covariance system at the Changling cornfield 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. It is located in Changling county, Jilin Province. The site is characterized by a typical agricultural ecosystem in Northeast China, with corn as the crop type. 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).
