Solar Fourier transform infrared spectra (Wollongong)

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.

伍伦贡大学（University of Wollongong, UOW）自1995年起在伍伦贡、2005年起在达尔文运营两座地基遥感站，持续开展大气成分监测工作。该监测技术采用高分辨率太阳傅里叶变换红外光谱（high resolution solar Fourier transform infrared spectroscopy），作为两个国际网络的组成部分——总碳柱观测网（Total Carbon column Observing Network, TCCON, https://tccon-wiki.caltech.edu/）与大气成分变化探测网（Network for Detection of Atmospheric Composition Change, NDACC, http://www.ndsc.ncep.noaa.gov/）。通过对光谱数据进行分析，可获取大气中40余种痕量气体的总柱含量。TCCON聚焦高精度温室气体监测，而NDACC的监测范围更广，涵盖与臭氧损耗及恢复相关的平流层气体。两类数据集均为连续观测序列，为大气成分研究提供了愈发珍贵的长期观测记录。
