METHODOLOGICAL INFORMATION

Description of methods used for collection/generation of data: 

Methods for processing the data: 
	Soil greenhouse gas (GHG) fluxes (CO2, N2O, CH4) measured using static chamber 	method used with 16-minute deployment per point
	Measurements recorded at 4-minute intervals

	Gasmet Technologies Oy. (2020). How to measure greenhouse gas soil fluxes. 	https://info.gasmet.com/hubfs/Greenhouse%20Gas%20Flux%20Measurement%20Guide%	20Gasmet%202020.pdf.

Instrument- or software-specific information needed to interpret the data: 
	FTIR GT5000 Terra gas analyser
	eosAC automated flux chamber

Standards and calibration information, if appropriate: 
	Gas analyser calibrated before each sampling using nitrogen gas

Environmental/experimental conditions: 
	Oil palm age: 9 years
	Soil type: Jawa series (Sulfic Endoaquepts)
	Mean annual temperature: 28.9°C
	Annual rainfall: 2301 mm

Describe any quality-assurance procedures performed on the data: 
	Only regression results with R² ≥ 0.8 used for gas data
