NOVAC: Global Network for Volcanic Gas Emissions & Atmospheric Change Studies

Join the NOVAC network to observe volcanic gas emissions & study atmospheric changes. Established using mini-DOAS instruments to aid geophysical research, risk assessment, & atmospheric change studies. Over 1.2 million emission measurements. Future focus includes risk assessment, research, instrument development, data exploitation, networking, and environmental impact studies.

Presentation Transcript

  1. NOVAC A Global Network for Observation of Volcanic Gas Emissions and studies of Atmospheric Change Based on results from EU-project DORSIVA

  2. NOVAC Network for Observation of Volcanic and Atmospheric Change EU-project Oct 2005 – March 2010 Aim: • To establish a network based on Dual-Beam Scanning mini-DOAS instruments on volcanoes. • To use the data for local geophysical research and risk assessment • To improve global gas assessments, validate satellites and study correlation of gas emission in time and space • In addition spectra will be used for atmospheric change research

  3. Installations completed May 2010 56 instruments installed on 22 volcanoes,

  4. The NOVAC Database 1.2 million emission measurements in the archive More then 1.7 million flux measurements

  5. Future Risk assessment DORSIVA NOVAC Geophysical research Instrument development Instrument implementation Data exploitation Networking Research Data exploitation Support existing network Maintain archive Supply instruments Provide platform Volcanology Atmospheric chemistry Environmental impact Instrument development Volcano risk assessment Climate change modelling Satellite validation Volcanic ash advisory
