    Description: The Measurements of Urban, Marine and Biogenic Air (MUMBA) campaign took place in Wollongong, New South Wales (a small coastal city approximately 80 km south of Sydney, Australia), from 21st December 2012 to 15th February 2013. Instruments were deployed during MUMBA to measure the gaseous and aerosol composition of the atmosphere with the aim of providing a detailed characterisation of the complex environment of the ocean/forest/urban interface that could be used to test the skill of atmospheric models. Gases measured included ozone, oxides of nitrogen, carbon monoxide, carbon dioxide, methane and many of the most abundant volatile organic compounds. Aerosol characterisation included total particle counts above 3 nm, total cloud condensation nuclei counts; mass concentration of PM2.5, number concentration size distribution, aerosol chemical analyses and elemental analysis. Meteorological measurements and LIDAR measurements were also performed. The campaign captured varied meteorological conditions, including two extreme heat events, providing a potentially valuable test for models of future air quality in a warmer climate. There was also an episode when the site sampled clean marine air for many hours, providing a useful additional measure of background concentrations of these trace gases within this poorly sampled region of the globe. Here we present the observations recorded at the MUMBA site during the campaign, as well as radon and air quality data from nearby sites. These records can be used for testing chemical transport models.

    Description: Location Spectrometer: Roof of 2 storey building at 2 Percy St, Auburn NSW 2144 Australia, -33.85472, 151.0373, 20.6 m rooftop above sea level, height rooftop above street level = 6.72 m; height measurement path above rooftop= 1.2 m Location Reflectors: Roof of 3 story building, Cumberland City Council, Auburn Office, at 1 Susan St Auburn 2144, Australia, -33.85311, 151.0335, 40.8 m rooftop above sea level, height roof top above street = 12.8 m, height mid-mirrors above rooftop = 2.4 m, Distance between Spectrometer and reflectors = 395.8 m one-way (instrument to reflector) + 1 m Return Measurement path = 792.6 m (including 1 m internal reflectance) Measurement Path Slope: = 5.3 Degrees; Difference in altitude = 20.9 m Measurement Path Bearing: 296.0278 degrees Gas Species Reported (units): Carbon Monoxide (CO, ppbv) Carbon Dioxide (CO2, ppmv) Nitrous Oxide (N2O, ppbv), Ammonia (NH3, ppbv), Methane (CH4, ppbv). Instrument description: The open path FTIR system is based on an FTIR spectrometer (Matrix-M IR cube, Bruker Optik, Ettlingen, Germany) which provides modulated infrared radiation with 1 cm-1 resolution from a globar source in a nominally parallel 25 mm diameter output beam. The beam passes through a beamsplitter (ZnSe window, 50 x 3 mm) to the secondary mirror of an on-axis beam expander which expands the beam diameter to 250 mm and reduces the divergence by a factor of 10. The beam expander was constructed from a modified 10 inch Schmidt-Cassegrain telescope (Model LX200R, Meade Instrument Corp., California, USA) by removing the standard Schmidt correction plate and secondary mirror and replacing it with a convex mirror of effective focal length 50mm. The beam expander is focussed by shifting the secondary mirror along the optic axis so that its focus is coincident with that of the primary mirror. An optically black mask ~ 5 mm in diameter at the centre of the secondary mirror blocks the back reflection of radiation to the detector from the centre of the mirror. The expanded beam follows an open path to 3 x 300 mm diameter retroreflector arrays (PLX Industries, New York, USA) located ~500 m distant from the spectrometer. The retroreflector returns the beam back on itself through the beam expander to the beamsplitter. The reflected beam from the beamsplitter is focussed by a 29 mm focal length 90 degrees off-axis paraboloidal mirror to a cooled MCT detector (Infrared Associates Inc., Florida, USA). The detector is cooled to liquid nitrogen temperature by a Stirling cycle mechanical refrigerator (RicorK508), removing the need for a liquid nitrogen supply in field applications. The FTIR spectrometer, beamsplitter, beam expander and detector are mounted on a single 100 mm optical rail to allow simple and robust alignment. The optical rail is mounted to a heavy duty tripod (Gibralter model 4-60450-OA, Quickset International Inc., Illinois, USA ) with a computer controlled Automated Instrument Mount (AIM Colterlec, Unanderra, Australia) to the allow accurate and stable alignment of the beam between spectrometer and retroreflector. The reported precision of the instrument is: NH3 1 ppb, N2O 0.6 ppb, CO2 0.5 ppm, CH4 2 ppb, CO 1 ppb. Data Collection Rate: average 5 min, timestamped at start of data collection period. Spectral Analysis: MALT (Griffith, D.W.T., Synthetic calibration and quantitative analysis of gas phase infrared spectra, Applied Spectroscopy, 50 (1), 59-70, 1996) with spectral parameters from HITRAN08 database (www.hitram.com). Spectral Micro Windows: CO2, N2O, CO and H2O 2150-2280 cm-1 CH4, H2O 3001-3140 cm-1 NH3, H2O 900-945 and 955-995 cm-1 Data QA: Data were removed when the maximum spectral intensity in the 2300 cm-1 spectral region was reduced to 〈 40% of the typical maximum value. Reduction in spectral intensity was typically due to rain, dew or dust on the telescope or retro-reflector surfaces. Calibration and Validation: Data (CO, CO2, CH4 and N2O) were compared with concurrent data from the Spectronus in-situ FTIR spectrometer. The regression results used to correct the OP-FTIR data (data collected at wind speed 〈 1 ms-1 were removed from the regression). Interruptions and Issues: Instrument Failure: UoW OP-FTIR OP3 failed with laser failure on 28 May 2017 14:15 and was replaced by OP5 on 31 May 2017 14:14; Optics on OP-FTIR updated on 16 June 2017 10:35. Instrument shut down when air temperature exceeded 42 C to protect instrument against over-heating.

    Description: It is recognised that Western Sydney experiences poorer air quality compared to the eastern suburbs due to the topography of the Sydney basin resulting in pollution produced in eastern Sydney being transported by the easterly sea breeze to Western Sydney, where it pools against the mountain range. As part of the Western Air-Shed and Particulate Study for Western Sydney (WASPSS), targeted air quality measurement campaigns were conducted in Western Sydney with the aim to identify hot spots for poor air quality and understand the variability in air quality in western Sydney, in particular how well the existing air quality monitoring network represents the air quality where people live. The measurement campaigns were operated in collaboration with the Office of Environment and Heritage (OEH), supplementing the information available from the ongoing OEH measurement network. The Auburn Air Quality measurement site was established on the roof a 2 story building at 2 Percy St, on the edge of the Auburn CBD in Western Sydney, and operated between 25 May 2016 and 9 September 2017. The site is adjacent to major rail line, used for heavy diesel freight, and major road networks. To the east is light industry, to the north and west is the Auburn CBD, with residential areas to the west. The site included a portable air monitoring station (OEH), containing instrumentation comparable to the OEH monitoring stations, an extended open path Fourier transform infrared (OP-FTIR) spectrometer, measuring atmospheric CO2, CO, N2O, CH4 and NH3 and an open path ultra-violet visible (UV-visible) Differential Optical Absorption Spectrometer (DOAS) measuring O3, SO2, NO2, HCHO & HONO. The two open path instruments operated with parallel measurement paths of ~ 400m, with the measurement paths terminated by mirror arrays located on the roof of a 3 story building within the Auburn CBD, on a small hill above the Percy St building. The open path FTIR and DOAS operated from October 2016 to March 2017, and May 2017 to September 2017. In August 2017 an in-situ FTIR tracer gas analyser (CO, CO2, N2O, CH4 and 13C in CO2) was installed with an air intake adjacent to the OEH monitoring station intake, and operated until September 2017. Meteorological data supplied by a 3D sonic anemometer from July 2017 to September 2017 complimented the weather station data from the portable monitoring station. Location: Roof of 2 storey building at 2 Percy St, Auburn NSW 2144, Australia, -33.85472, 151.0374; Height: roof top above sea level 20.6 m; height rooftop above street level 6.72m Site operational Dates: 28-October-2016 13:00 to 18-September-2017 13:00 Time zone: Australian Eastern Standard Time, UTC+10 hours

    Description: We assess the performance of an inverse Lagrangian dispersion technique for its suitability to quantify leakages from geological storage of CO2. We find the technique is accurate ((QbLS/Q)=0.99, sigma=0.29) when strict meteorological filtering is applied to ensure that Monin–Obukhov Similarity Theory is valid for the periods analysed and when downwind enrichments in tracer gas concentration are 1% or more above background concentration. Because of their respective baseline atmospheric concentrations, this enrichment criterion is less onerous for CH4 than for CO2. Therefore for geologically sequestered gas reservoirs with a significant CH4 component, monitoring CH4 as a surrogate for CO2 leakage could be as much as 10 times more sensitive than monitoring CO2 alone. Additional recommendations for designing a robust atmospheric monitoring strategy for geosequestration include: continuous concentration data; exact inter-calibration of up- and downwind concentration measurements; use of an array of point concentration sensors to maximise the use of spatial information about the leakage plume; and precise isotope ratio measurement to confirm the source of any concentration elevations detected.

    Description: Speleothem palaeo-climate records rely on the transfer of external weather and climate signals to growing speleothems in the cave environment. Both cave atmosphere and drip-water chemistry affects this signal transfer. Speleothem growth may be detected by measuring the isotopic composition of CO2 in the cave atmosphere. Our study was designed to measure the rapid response of cave atmosphere to changes in external weather and the incorporation of environmental signals into speleothems. The approach to data collection was to define the sources and sinks of trace gases in the cave measured at high frequency (hour) to match rapid changes in weather, principally temperature, which drives convective cave ventilation. This time series data-set collected at the Jenolan Caves experiment site in NSW, Australia is the first long-term (3 yr) continuous measurement of d13C in CO2 and CH4 in-situ in a cave. Spectroscopic methods, Cavity Ring Down Spectroscopy (CRDS) and Fourier Transform Infra Red (FTIR) were used. In addition to d13C in CO2 and CH4, time-series data for N2O, CO and 222Rn were also recorded.
