Gas metrology: Comparisons
The comparisons run by the BIPM form part of the CCQM and its Gas Analysis (CCQM-GAWG) and Isotope Ratio (CCQM-IRWG) Working Group activities to enable NMIs to demonstrate their measurement capabilities in the areas of:
- greenhouse gases, demonstrating consistency at levels required to support national energy and environmental priorities;
- major air-quality gases, demonstrating consistency at levels required to support national health and environmental priorities.
