However, little is known about their SO2 contribution into the atmosphere, due to isolation and access difficulties. Existing SO2 emission budgets for the Indonesian archipelago are based on extrapolations and inferences as there is a considerable lack of field assessments of degassing. Here, we present the first SO2 flux measurements using differential optical absorption spectroscopy (DOAS) for Papandayan and Bromo, two of the most active volcanoes in Indonesia. Results indicate mean SO2 emission rates of 1.4 t d(-1) from the fumarolic activity of Papandayan and more than 22-32 t d(-1) of SO2 released by Bromo during a declining eruptive phase. These DOAS results are very encouraging and pave the way for a better evaluation of Indonesian volcanic emissions. specialized INDONESIE 066 13 10 2399-2407 2013 1561-8633 https://www.documentation.ird.fr/hor/fdi:010061331 10.5194/nhess-13-2399-2013 1561-8633 [F B010061331] https://www.documentation.ird.fr/hor/fdi:010061331 https://www.documentation.ird.fr/intranet/publi/2013/12/010061331.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2013-12-23 2020-08-28 fdi:010061331 fre
