Description

This event will explore recent advances in metrology for SHI technologies and their application within the CTBTO verification regime. It will focus on the transfer of laboratory calibration methods to the field, address key technical challenges, and highlight the importance of strengthening calibration traceability to ensure reliable IMS data.

Session Objectives:
- Review the most recent developments in metrology related to IMS seismic, hydroacoustic, and infrasound (SHI) monitoring, representing the state-of-the-art.
- Consider how laboratory calibration capability can be transferred to the field calibration requirements of the IMS.
- Outline the technical challenges and highlight further research necessary to fully implement field calibration requirements and establish measurement traceability for IMS seismic, hydroacoustic and infrasound data.
- Encourage manufacturers of SHI equipment and operators of SHI systems outside the IMS to contribute to the developments in metrology related to instrumentation and adopt a unified approach to calibration techniques compatible with IMS methods and requirements.

This side event provides an opportunity to share experiences and successes from across technologies and from geophysical monitoring activities beyond the IMS.
