A dataset of carbon, water and heat fluxes over an Elymus nutans artificial grassland in the Sanjiangyuan Area (2012–2016)

This dataset includes routine meteorological data subset (air temperature, air relative humidity, water vapor pressure, soil temperature, soil moisture, photosynthetically active radiation, and precipitation) and carbon, water, and heat fluxes data subset (net ecosystem CO2 exchange, ecosystem CO2 respiration, gross ecosystem CO2 exchange, latent heat flux, and sensible heat flux) on a half-hour, day, month, and year scale.

This dataset provides field observational data support for scientific knowledge, remote sensing retrieval, and model validation in exploring spatiotemporal patterns of carbon, water, and heat exchanges in Elymus nutans artificial grassland.
