Solar Fourier transform infrared spectra (Darwin)

UOW has operated two ground based remote sensing stations measuring atmospheric composition continuously at Wollongong since 1995 and Darwin since 2005. The measurement technique is high resolution solar Fourier transform infrared spectroscopy as part of two international networks - the Total Carbon column Observing Network (TCCON, https://tccon-wiki.caltech.edu/) and Network for Detection of Atmospheric Composition Change (NDACC, http://www.ndsc.ncep.noaa.gov/). Spectra are analysed to provide total column amounts of over 40 trace gases in the atmosphere. TCCON is focused on high accuracy greenhouse gas measurements, and NDACC a wider range including stratospheric gases involved in ozone depletion and recovery. Both datasets are continuous and provide an increasingly valuable long term records of atmospheric composition.
