International comparisons of ozone standards (BIPM.QM-K1)
BIPM.QM-K1 is an ongoing key comparison for ozone reference standards and capabilities.
Coordinated by the BIPM, 21 National Metrology Institutes or Designated Institutes have been taking part in this comparison since its start in 2007. The WMO World Calibration Center for surface ozone has participated, and the WMO guidelines for continuous measurement of ozone in the troposphere recognize BIPM.QM-K1 as the way to demonstrate metrological traceability of surface ozone measurements.
The comparison protocol and associated forms can be downloaded from this page. Completed registration forms should be sent to the comparison coordinator, Dr J. Viallon (BIPM).
