EMPIR project STELLAR started with a kick-off-meeting on 17. September 2020 in the form of web conference.
STELLAR is a continuation of SIRS project. Where reference gases for stable isotope analysis have been developed. The project is coordinated by National Physical Laboratory from UK and includes partners form United Kingdom, Denmark, Italy, Germany, Turkey, Netherlands, Finland, Spain, Switzerland, and Slovenia.
The objectives of the project are:
- To develop gas reference materials of carbon dioxide and methane as pure gases and as ambient air mol fractions with even lower low target uncertainties.
- To develop SI traceable methods for absolute isotope ratio measurements of carbon dioxide.
- To develop and metrologically characterise field deployable spectroscopic methods and calibration approaches for isotope ratio measurements of carbon dioxide and methane.
- To facilitate the take-up of the technology and measurement infrastructure developed in the project by the measurement supply chain, standards developing organisations, and end users.
