Guidelines for the Measurement of Atmospheric Carbon Monoxide
The Global Atmosphere Watch (GAW) Programme of the World Meteorological Organization (WMO) aims at providing reliable long-term observations of the chemical composition and physical properties of the atmosphere that are relevant for understanding atmospheric chemistry and climate change. Reactive gases are one of the foci of the GAW programme. This group includes carbon monoxide (CO), which is present only in trace quantities in the atmosphere but plays an important role in atmospheric chemistry. Compatibility of data from different observational platforms and sites is of crucial importance for the early detection of global trends or slight variations in chemical composition of the atmosphere. In many cases, decades of time series are required to assess these changes with a certain degree of confidence. Support of the long-term stability of the reference scales and its propagation to in-situ measurements are particular prerequisites to meet these demands. In this document we focus on continuous in-situ and flask measurements of carbon monoxide performed from different platforms.
