A dataset of observed carbon fluxes on deciduous broad-leaved forest at the Maoershan Station from 2016 to 2018

In this dataset, we compiled the measured carbon flux data and routine meteorological data of a deciduous broad-leaved forest in Maoershan Station from 2016 to 2018, including gross primary productivity, ecosystem respiration, net ecosystem exchange, incoming solar radiation, incoming photosynthetically active radiation, air temperature, soil temperature, soil moisture and precipitation, forming data products with time scales of half-hour, daily, monthly and yearly. Carbon flux data are measured by an open-path eddy covariance system and meteorological data are automatically acquired and stored by the corresponding data acquisition system on the flux tower. It should be noted that precipitation is observed manually and includes 3 time scales: daily, monthly and yearly. Data for soil moisture in 2017 are partially missing due to an equipment failure.The content and meaning of the fields in the Excel file column labels in this dataset are explained as follows: SR (incoming solar radiation), PAR (incoming photosynthetically active radiation), Ta (air temperature), VPD (vapor pressure deficit), Ts (soil temperature), Ms (soil moisture), Rain (precipitation).
