1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Santiago Arellano <santiago.arellano@xxxxxxxxxxx> Dear Colleagues, The NOVAC <https://novac-community.org/> (Network for Observation of Volcanic and Atmospheric Change) is a global collaboration of volcano observatories and research institutions for monitoring of volcanic gas emissions using ground-based remote sensing. We are pleased to present a detailed database of SO2 emission, plume location and meteorological conditions, derived from measurements conducted during the period 2005-2016 at 32 volcanoes in NOVAC. The database is hosted at https://novac.chalmers.se/. Data presented in this database is to a large extent complementary to data obtained by space-based sensors during the same period, and indicates the magnitude and natural variability of degassing observed at a daily temporal scale. These data are freely accessible but we expect that proper credit is given to volcano observatories in case of scientific use, as indicated in our Data Use Agreement <https://novac.chalmers.se/datauseagreement>. An article describing and analyzing these data was published by the collaboration (Arellano et al., 2021 <https://essd.copernicus.org/articles/13/1167/2021/essd-13-1167-2021.html>). Kind Regards, The NOVAC collaboration 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ------------------------------
