One of the goals of NOVAC is to disseminate instrumentation, background knowledge, and experience in monitoring and data interpretation for the benefit of all partners. In this context, the 6th NOVAC workshop was held in Arequipa and Chivay, Peru from 22 to 29 April, 2018. At the workshop, 42 participants from 20 countries gathered to discuss their experience monitoring volcanic degassing using passive scanning DOAS. The workshop was co-organized by Christoph Kern of the USGS Volcano Disaster Assistance Program (VDAP) and Pablo Masias and Fredy Apaza of the Peruvian Instituto Geológico, Minero y Metalurgico (INGEMMET-OVI).
