A dataset of carbon and water fluxes of the cropland ecosystem at Changwu Station in 2020

The dataset is a standardized dataset of ecosystem carbon and water fluxes and key meteorological elements developed based on ChinaFLUX data processing specifications. The raw observation data were collected at the National Field Scientific Observation and Research Station of Farmland Ecosystem in Changwu County, Shaanxi Province in 2020. The dataset consists of 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).
