Monitoring data and their analysis are central to the verification effort of the CTBT/CTBTO. It is often emphasized that the data belong to the Member States. A State Signatory has the right of full access to all monitoring data and data bulletins, which can assist a State in exercising its prerogative to make the final judgement in the case of a suspicious event.
In order to enable Member States to come to an informed judgement on a suspicious event, they need to have at their disposal all raw data and data analysis results in a reliable, equal and timely fashion. The International Data Centre (IDC) makes sure that these requirements are met and is supported in its efforts by the Global Communications Infrastructure (GCI).
Over 900 users in 100 States are currently authorized to receive CTBTO data and data bulletins. And the numbers are increasing. Who are these users and who authorizes them?
A Member State that wants to use its right of full access to monitoring data and analysis reports must establish a secure signatory account with the CTBTO. This is the mechanism by which authorized users can communicate with the IDC and transfer data securely. The person responsible for overseeing and managing this account is the principal point of contact.
