BIPM News:
National Measurement Institutes demonstrate high accuracy reference measurement system for SARS-CoV-2 testing Twenty-one National Metrology Institutes and expert laboratories from sixteen countries have demonstrated that highly accurate measurements of the amount of the SARS-CoV-2 viral RNA can be achieved worldwide using reverse transcription-digital PCR (RT-dPCR). The comparison study (CCQM-P199.b) is organized by the CCQM Working Group on Nucleic Acid Analysis (CCQM-NAWG). New series of virtual seminars on ionizing radiation metrology The field of ionizing radiation metrology is constantly evolving, ensuring the effectiveness and safety of new cancer treatments being just one example. A series of international scientific virtual seminars has been launched to share information on progress in the field. Towards more accurate monitoring of surface ozone Participants at the BIPM virtual workshop on 'Accurate Monitoring of Surface Ozone' from air quality monitoring networks, environment agencies, instrument manufacturers and metrology institutes, agreed to work together to develop an implementation plan to enable more accurate surface ozone measurements world-wide. The workshop was held from 5 to 9 October 2020. Work by the NMIs to support the fight against COVID-19. A repository of actions The CIPM President has asked NMIs to share examples of how their work is supporting the fight against the COVID-19 pandemic. The responses received are listed in a dedicated 'Metrology in the fight against Covid-19' repository. First frequency comparison of distant optical clocks by VLBI and IPPP An international collaboration between the NICT, INRIM, INAF and BIPM has successfully achieved the frequency comparison of distant optical clocks using two independent radio techniques, VLBI and IPPP. Symposium to celebrate the centenary of the award of the Nobel Prize in Physics to Charles-Édouard Guillaume On 17 October 2020, the BIPM will celebrate the life and work of Charles-Édouard Guillaume with a symposium that will consider his legacy.

The BIPM's mission and role:

  • Our vision is to be universally recognized as the world focus for the international system of measurement.

  • Our mission is to work with the NMIs of our Member States, the RMOs and strategic partners world-wide and to use the BIPM's international and impartial status to promote and advance the global comparability of measurements.
