1. This is the dataset for our research on greenhouse gas emissions from representative river catchments in China. Field sampling and laboratory analysis were financially supported by the Research Grants Council of Hong Kong (grants: 27300118 and 17300619) and the National Natural Science Foundation of China (grant: 41807318).

DATA DESCRIPTION
---------------------

For the Sheet 'Streams':
This sheet includes water quality and GHG concentrations and effluxes at stream sites in the Jing River catchment during four sampling campaigns (August and October 2018 and March and June 2019). There were thirty nine (39) stream sites, from R1 to R39. Symbol ‘-’ represent no data.
Column A: Sampling site from R1 to R39
Column B: Location of the sampling site (Longitue E)
Comumn C: Location of the sampling site (Latitude N)
Columns D, M, V and AE: pH in surface water
Columns E, N, W and AF: Concentration of dissolved oxygen (DO)
Comumns F, O, X and AG: Concentration of dissolved organic carbon (DOC)
Columns G, P, Y and AH: Concentration of dissolved inorganic carbon (DIC)
Columns H, Q, Z and AI: CO2 partial pressure (pCO2) in surface water
Comumns I, R, AA and AJ: CO2 emission flux
Columns J, S, AB and AK: Dissolved CH4 concentration 
Columns K, T, AC and AL: CH4 emission flux (diffusion)
Comumns L, U, AD and AM: CH4 emission flux (ebullition)

For the Sheet 'Reservoirs':
This sheet includes water quality and GHG concentrations and effluxes at reservoir sites in the Jing River catchment during four sampling campaigns (August and October 2018 and March and June 2019). There were five (5) reservoir sites, from S1 to S5.
Column A: Sampling site from S1 to S5
Column B: Location of the sampling site (Longitue E)
Comumn C: Location of the sampling site (Latitude N)
Columns D, M, V and AE: pH in surface water
Columns E, N, W and AF: Concentration of dissolved oxygen (DO)
Comumns F, O, X and AG: Concentration of dissolved organic carbon (DOC)
Columns G, P, Y and AH: Concentration of dissolved inorganic carbon (DIC)
Columns H, Q, Z and AI: CO2 partial pressure (pCO2) in surface water
Comumns I, R, AA and AJ: CO2 emission flux
Columns J, S, AB and AK: Dissolved CH4 concentration 
Columns K, T, AC and AL: CH4 emission flux (diffusion)
Comumns L, U, AD and AM: CH4 emission flux (ebullition)
