The global carbon cycle and the distribution, sources and sinks of greenhouse gases such as carbon dioxide and methane are crucial drivers of climate change. The Total Carbon Column Observing Network (TCCON) measures the amounts of greenhouse and other trace gases in the atmosphere by solar remote sensing from the ground with unprecedented accuracy and precision. TCCON data are the "gold standard" for total column measurements and an essential part of greenhouse gas science. They are used to improve knowledge of the carbon cycle and future climate change, both directly and by validating global-scale satellite measurements. This project will continue to expand TCCON in the southern hemisphere and the enhanced scientific understanding it will provide.

全球碳循环以及二氧化碳和甲烷等温室气体的分布、来源和汇是气候变化的关键驱动因素。总碳柱观测网络（TCCON）通过从地面进行太阳遥感，以前所未有的准确度和精度测量大气中的温室气体和其他痕量气体的数量。TCCON数据是总柱测量的“黄金标准”，也是温室气体科学的重要组成部分。它们被用于直接或通过验证全球范围的卫星测量来提高对碳循环和未来气候变化的认识。该项目将继续在南半球扩大TCCON，并加强其提供的科学认识。
