title: Supporting data for "Hydrology regulates sources and sinks of CO<sub>2</sub> and CH<sub>4</sub> in a tropical headwater stream"

description: These files contain supporting data for the aforementioned manuscript. <br>Timeseries.csv and SynopticSamples.csv contain observational data from the study system. MetabolismOutputs.csv contain the modelled results of in-stream metabolism. CO2endmembers.csv and CH4endmembers.csv contain the modelled mass balance components. A brief description of each file and the columns is below. For more details on methods, see the manuscript. <br><b>Timeseries</b>DateTime: YYYY-MM-DD HH:MM:SSDate: YYYY-MM-DDDO.up: upstream measurement of dissolved oxygen; mg/LDO.pct.up: upstream measurement of dissolved oxygen; % saturationDO.dn: downstream measurement of dissolved oxygen; mg/LDO.pct.dn: downstream measurement of dissolved oxygen; % saturationTemp.up: upstream measurement of water temperature; CTemp.dn: upstream measurement of water temperature; CWL.up: upstream water level: mWL.dn: downstream water level: mQ.up: upstream discharge; L/sQ.dn: downstream discharge; L/sCO2M.up: upstream CO<sub>2</sub> concentration; uMCO2M.dn: downstream CO<sub>2</sub> concentration; uMMaxedOutTrue: if TRUE, indicates the upstream sensor was recording values outside it's measurement rangePAR.up: upstream photosynthetic radiation; umol m<sup>-2</sup> d<sup>-1</sup>PAR.dn: downstream photosynthetic radiation; umol m<sup>-2</sup> d<sup>-1</sup><br><b>SynopticSamples</b>Date: YYYY-MM-DDID: Site IDSystem: site type; CR (stream), PZ (Piezometer) or SS (Subsurface flow)Temperature: Water temperature; CDO: Dissolved oxygen; mg L<sup>-1</sup>DO.pct: Dissolved oxygen; % saturationpH: pHCO2: carbon dioxide concentration; molCH4: methane concentration; molCH4.13; stable isotopic signature of CH4: ‰<b>MetabolismOutput</b>date: YYYY-MM-DDGPP.daily: gross primary production; g O<sub>2</sub> m<sup>-2</sup> d<sup>-1</sup>ER.daily: ecosystem respiration; g O<sub>2</sub> m<sup>-2</sup> d<sup>-1</sup>NEP.daily: net ecosystem production; g O<sub>2</sub> m<sup>-2</sup> d<sup>-1</sup>GPP.daily.sd: gross primary production standard deviation; g O<sub>2</sub> m<sup>-2</sup> d<sup>-1</sup>ER.daily.sd: ecosystem respiration standard deviation; g O<sub>2</sub> m<sup>-2</sup> d<sup>-1</sup>GPP.daily.sd.C: gross primary production standard deviation; g C m<sup>-2</sup> d<sup>-1</sup>ER.daily.sd.C: ecosystem respiration standard deviation; g C m<sup>-2</sup> d<sup>-1</sup>NEP.daily.sd.C: net ecosystem production standard deviation; g C m<sup>-2</sup> d<sup>-1</sup>GPP.daily.C: gross primary production; g C m<sup>-2</sup> d<sup>-1</sup>ER.daily.C: ecosystem respiration; g C m<sup>-2</sup> d<sup>-1</sup>NEP.daily.C: net ecosystem production; g C m<sup>-2</sup> d<sup>-1</sup>Interpolated: Indicates if at least one parameter (ER or GPP) was interpolated<br><b>CO2endmembers</b>Date: YYYY-MM-DDCO2.in: Upstream import; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.out: downstream export; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.lat: lateral import; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.met: metabolism input; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.ox; production of CO<sub>2</sub> from CH<sub>4</sub> oxidation; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.atm; atmospheric flux; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.in.err:Upstream import error; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.out.err: downstream export error; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.lat.err: lateral import error; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.met.err: metabolism input error; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.ox.err: production of CO<sub>2</sub> from CH<sub>4</sub> oxidation error; g C-CO<sub>2</sub> d<sup>-1</sup>CO2.atm.err; atmospheric flux error; g C-CO<sub>2</sub> d<sup>-1</sup><b>CH4Endmembers</b>Month: Sample month; numericCH4.in: upstream import; g C-CH<sub>4 </sub>d<sup>-1</sup>CH4.out: downstream export; g C-CH<sub>4 </sub>d<sup>-1</sup>CH4.lat: lateral import; g C-CH<sub>4 </sub>d<sup>-1</sup>CH4.ox: consumption of CH<sub>4</sub> from oxidation; g C-CH<sub>4 </sub>d<sup>-1</sup>CH4.atm: atmospheric flux; g C-CH<sub>4 </sub>d<sup>-1</sup>CH4.in.err: upstream import error; g C-CH<sub>4 </sub>d<sup>-1</sup>CH4.out.err: downstream export error; g C-CH<sub>4 </sub>d<sup>-1</sup>CH4.lat.err: lateral import error; g C-CH<sub>4 </sub>d<sup>-1</sup>CH4.ox.err: consumption of CH<sub>4</sub> from oxidation error; g C-CH<sub>4 </sub>d<sup>-1</sup>CH4.atm.err: atmospheric flux error; g C-CH<sub>4 </sub>d<sup>-1</sup><br><br>
