BIPM News:
Time Department launches database and interactive tool for time scale contributors The BIPM Time Department has launched a new database and interactive tool for time scale contributors that is updated monthly with an inventory of laboratories that contribute to UTC and UTCr, their equipment and calibrations. BIPM-WADA Symposium on Standards and Metrology in support of Anti-Doping Analysis The BIPM hosted a joint symposium with the World Anti-Doping Agency (WADA) on 28-29 September. One hundred invited experts from NMIs, the clinical chemistry and laboratory medicine community and from WADA and the WADA-accredited anti-doping laboratories discussed the latest initiatives in areas of metrology for organic and biological analysis relevant to this high-profile measurement sector. JCRB meeting held in east Africa for the first time The JCRB met in Nairobi (Kenya) on 14-15 September 2016. This marked the first time it has met in east Africa. Discussions centred around the actions and recommendations of the Working Group on the Implementation and Operation of the CIPM MRA. Human Resources collaboration between NIST and the BIPM As part of the BIPM's objective to continuously improve its administrative procedures, Ms Susanne Porch, Human Resources Director, NIST (USA), visited the BIPM on 5-8 September 2016 to share experience on HR best practices. Pioneering research improves the stability of timescale computation A paper entitled "A new approach to UTC calculation by means of the Kalman filter" has been published in Metrologia following a collaborative research project in the Time Department. Katharine Gebbie (1932-2016) We are sorry to report the death of Katharine Gebbie on 17 August 2016 at the age of 84. Dr Gebbie was a visionary physicist and senior government research administrator at NIST (USA). Her contributions to international metrology were highly regarded around the world and included membership of the CIPM from 1994 to 2000, where she served as Vice-President for three years. Leap second to be added to UTC at end of 2016 The IERS has announced that a leap second will be added to UTC at the end of 2016.

The BIPM's mission and role:

The mission of the BIPM is to ensure and promote the global comparability of measurements, including providing a coherent international system of units for:

  • Scientific discovery and innovation,
  • Industrial manufacturing and international trade,
  • Sustaining the quality of life and the global environment.

The unique role of the BIPM enables it to achieve its mission by developing the technical and organizational infrastructure of the International System of Units (SI) as the basis for the world-wide traceability of measurement results. This is achieved both through technical activities in its laboratories and through international coordination.
