DESCRIPTION:Speakers: Paulina Bittner (CTBTO Preparatory Commission\, Vien
 na\, Austria)\, Nicolas Brachet (Commissariat à l’énergie atomique et 
 aux énergies alternatives (CEA)\, France )\, Arora Nimar (Bayesian Logic)
 \, Ronan Le Bras (CTBTO Preparatory Commission\, Vienna\, Austria)\, David
  Brown (Former CTBTO Preparatory Commission\, Vienna\, Austria)\, Pierrick
  Mialle (CTBTO Preparatory Commission\, Vienna\, Austria)\n\nIn 2001\, whe
 n the first data from an IMS infrasound station started to arrive in near 
 real-time at the IDC\, its infrasound processing system was in a premature
  state. The IDC then embarked for a multi-year design and development of i
 ts dedicated processing system\, which led to operational IDC automatic pr
 ocessing and interactive analysis systems in 2010. The IDC went on in the 
 next ten years to produce over 40\,000 infrasound events reviewed by exper
 t analysts.\nIn an effort to continue advancing its methods\, improving it
 s automatic system and providing software packages to CTBTO users\, the ID
 C focused on several projects. First\, the automatic system for the identi
 fication of valid signals was redesigned with the development of DTK- PMCC
  (Progressive Multi-Channel Correlation)\, which is made available to CTBT
 O users within NDC-in-a-Box. And second\, an infrasound model was develope
 d for automatic waveform network processing software NET-VISA with an emph
 asis on the optimization of the network detection threshold by identifying
  ways to refine signal characterization methodology and association criter
 ia.\nFuture improvements of the IDC processing system are planned to furth
 er reduce analyst workload that includes atmospheric propagation modeling 
 and enhancements of the automatic pipeline components.\n\nhttps://conferen
