A dataset of carbon and water fluxes of the grassland ecosystem at Siziwang Station (2017, 2019-2020)

This dataset includes the flux observation data of the Siziwang grassland ecosystem in 2017 and 2019-2020. The raw observation data were collected at the Siziwang grassland flux observation station. The station is administrated by the Inner Mongolia Academy of Agricultural and Animal Husbandry Sciences, located in the south central area of Siziwang Banner, Ulanqab City, Inner Mongolia. The vegetation type belongs to desert steppes. Based on the ChinaFLUX data processing spefications, we processed the raw observation data to produce this standardized dataset of ecosystem carbon and water fluxes and key meteorological elements. In the dataset, the data for each year 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).
