The objectives for the NDC Capacity Building Workshop are:
- To strengthen participants’ knowledge of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) and the work of the Preparatory Commission;
- To further build up the national and regional capacities in implementing the Treaty and participating in the verification regime;
- To promote the civil and scientific application of verification technologies;
Additional objectives for the RSTT and Data Sharing and Integration Training are:
- To recognize the importance of obtaining better regional locations for future tomographic studies;
- To understand and learn how the RSTT model can help regional networks achieve more precise event locations;
- To learn how RSTT can be interfaced with current locators used in daily earthquake location procedures;
- To demonstrate the importance of Ground-Truth (GT) event locations in defining regional seismic velocity structures and models;
- To share data and to develop the Regional Seismic Travel Time Model (RSTT) in Middle East and South Asia (MESA) through the acquisition of GT seismic locations;
- To integrate local or regional non-IMS data with the NDC-in-a-Box software for event location;
- To stimulate regional cooperation in data exchange through the NDCs and/or regional network operators.
NDC Capacity Building
- Presentations of the latest developments, regarding the IMS, the IDC and capacity building and training;
- National experiences in establishing and operating an NDC and/or experience with the CTBTO: Speakers from each State Signatory in the MESA region represented at the workshop (15 minutes each);
- Establishment, operation and assistance of NDCs;
- Civil and scientific applications of IMS data and IDC products with emphasis on special interest to NDCs in MESA;
- Introduction to the RSTT project and data sharing activities.
Presentations and discussions on:
- Theoretical aspects behind the RSTT model and other 2.5D or 3D seismic velocity models
- Computational efficiency of the RSTT method.
- Tessellation grid and the importance of crustal parameters data input (compilation of published references).
- Availability of ground truth events (GT) and the need to test the model.
- How regional phase data exchange can help better understanding the regional crustal structure through tomographic studies.
Hands-on exercises on RSTT data sets:
- An introduction to Python and Jupyter
- Measurement of regional arrival times.
- Location of events using regional data.
- Combining regional and local data.
- Combining regional and teleseismic data.
- Testing location accuracy.
- Evaluation of residuals.
- Comparison with ground truth and other reference events.
- Establishing new reference (ground truth) events.
Applicants should be involved in the use of IMS Data and Products, in particular NDC analysts, scientific staff from seismological observatories, and/or tsunami warning centres or researchers from academic institutions with seismological background and experience The Workshop aims at having a broad representation from the MESA region.
Participation in the training requires the participants to have an advanced degree in seismology and/or geophysics, a good command of the English language and have worked in areas related to tomography, receiver functions, regional seismic studies and earthquake data processing. Participation in previous RSTT related activities is an asset. The tools that will be presented during the training are written in Python. Although experience in Python per se is not required (there will be a basic introduction to Python), experience with any programming language will be helpful.
It is highly recommended that participants bring their own laptops, with at least 20 GB free hard disk space and 4 GB (preferably 8 GB) of RAM to enable the use of the Virtual Machine and other software that will be provided by the Commission to efficiently perform the activities related to the Workshop.
Applicants are requested to visit our website Opens external link in new windowctnw.ctbto.org and apply online latest by 1 July 2020.
Financial support may be available for a limited number of participants. Such assistance must be requested at the time of registration (by selecting the relevant box during online registration).
States Signatories wishing to nominate experts are requested to inform the Provisional Technical Secretariat (see Point of Contact) through their respective Permanent Mission.
In accordance with the Staff regulations and rules and Administrative Directives, the PTS will provide the candidates with daily subsistence allowance (DSA) and financial support to cover the travel costs.
- The DSA will be sufficient for expenses during the workshop and training program;
- The PTS travel agent will reserve, issue and send tickets to the participants for the most direct and economic route;
- Funded participants are not allowed to purchase their own tickets unless, under exceptional circumstances, they are authorized to do so and only if this proves to be more cost efficient for the PTS;
- Health insurance will be provided for the duration of the workshop and training.
OTHER PERTINENT INFORMATION
The Training is available to a limited number of participants.
Participants should apply for visas, if needed, at the corresponding Consular office as soon as possible and upon receipt of an acceptance Note Verbale from the Provisional Technical Secretariat in order to ensure timely processing.
It is strongly recommended that prior to departure all participants acquire health and accident insurance for the duration of the workshop and training.
