A dataset of carbon dioxide flux from Chongming Dongtan Wetland of Shanghai during 2004-2010
As one of the standard methods of micrometeorology,eddy covariance technology has become the primary tool for monitoring the exchange of carbon dioxide,water and heat flux between terrestrial ecosystems and the atmosphere.This dataset includes the flux data accumulated by the National Observations and Research Station for Wetland Ecosystems in the Yangtze Estuary,collected in Dongtan Wetland on Chongming Island,Shanghai from September 2004 to December 2010,with a time resolution of half hour,and the data items cover air temperature(T_air),relative humidity(RH),soil temperature(T_soil),photosynthetically active radiation(PAR),solar radiation(Solar),net radiation(Rn),rainfall(Precip),sensible heat flux(Hs),latent heat flux(LE)and net carbon dioxide exchange(NEECO2),etc.The ecosystem observed in this study is typical of subtropical coastal salt marshes,predominantly inhabited by such plants as Phragmites australis and Spartina alterniflora.The observation system setup,equipment maintenance,data processing and quality control follows FLUXNET recommended protocols,ensuring high data reliability.The dataset can provide solid data support for the carbon budget,blue carbon estimation and biological invasion impact assessment of China's coastal salt marshes.
