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
