Measurement: CO2, CO, CH4, N2O and 13C in CO2
Instrument: in situ FTIR greenhouse gas and isotope analyser (Griffith 2012)
Owner: UOW
Campaign: MUMBA
Location: Main measurement site - Nissan Hut Kids Campus / Campus East, Wollongong (-34.3972, 150.8996)
Dates of operation: 21-Dec-2012 to 15-Feb-2013
Original measurement time resolution: ~3 minutes
Averaging time: 1 hour
Units: 	ppm for CO2
	ppb for CO, CH4, N2O  
	per mil del13C in CO2

Inlet/Installation detail (inc. flow rate if relevant): Inlet height: ~10m. Flow: 1 L/minute. Air was passed through a membranous (Nafion) dryer, followed by a chemical (Mg(ClO4)2) dryer.
Data/sample collection detail: Ambient measurements were collected over 23.5 hours with the remaining 0.5 hours dedicated to measurements of air of constant composition (target tank). Target tank measurements began at midnight.
Data/sample analysis detail (inc. references if needed): Trace gas mole fractions were retrieved over four broad spectral regions (2097-2242, 2150-2310, 3001-3150, and 3520-3775 cm-1) using the non-linear least-squares program MALT (Multiple Atmospheric Layer Transmission) (Griffith et al., 2012).
Calibration: The instrument measured from a target tank daily, and complete calibration was performed at the start and at the end of the campaign using three tanks of constant, but differing composition and traceable to the WMO scale through CSIRO's Gaslab
Precision and accuracy: meet the World Meteorological Organisation - Global Atmosphere Watch standards for baseline air for CO2, CO, CH4 and N2O (Griffith 2012)

Issues: The cell temperature went above the range calibrated for on 18-Jan-2013. This period was excluded from the dataset 
Corrections: data were corrected for cross-sensitivity to parameters such as pressure and flow determined using a set of experiments as described in Hammer et al 2013.
Uncertainties (conservative): CO2 0.5 ppm (0.1%), CH4 2 ppb (0.1%), N2O 0.3ppb (0.1%), CO 1 ppb (2% at 50 ppb)
