Global Network Measurements of Atmospheric Trace Gas Isotopes

Abstract

The Earth’s atmosphere is critical to life on Earth and human activities have been altering its composition since at least the industrial revolution. The global climate change during the twenty-first century will very likely be larger than that observed during the twentieth century. Atmospheric monitoring programs provide critical observations with long-term direct measurements of greenhouse gases and their isotopes that help constrain our understanding of that global climate change by driving models that improve our knowledge of biosphere/ocean processes at the heart of the climate system. In this chapter we highlight the importance of global atmospheric monitoring, explore several global measurement programs, and outline the critical elements necessary to operate these observational networks. We revisit the criteria necessary for intercomparison and linking of atmospheric isotopic data sets from the global measurement community, and present some recent data products and results for isotopic models that shed important light on sources and sinks of greenhouse gases.
