At this meeting will be discussed the outcome of the European metrology research project SRT-v04, running 2013-2017, on new standards and measurement methods for important greenhouse gases. In particular will be discussed 1) development of new dynamic generation methods to produce SI-traceable, trace concentration reference gas mixtures for CO, N2O and F-gases; and 2) new spectroscopic methods for isotopic composition measurements of CO2, CH4 and N2O and transfer standards.
Results of interest for the scientific community will be presented in session AS3.27.
