From:Atmospheric Measurement Techniques (Vol. 9, Issue 12) Peer-ReviewedScanning spectrometer networks using scattered solar radiation in the ultraviolet spectral region have become an increasingly important tool for monitoring volcanic sulfur dioxide (SO.sub.2) emissions. Often measured...

From:Atmospheric Chemistry and Physics (Vol. 21, Issue 5) Peer-ReviewedVolcanic emissions are a source of halogens in the atmosphere. Rapid reactions convert the initially emitted hydrogen halides (HCl, HBr, and HI) into reactive species such as BrO, Br.sub.2, BrCl, ClO, OClO, and IO. The...

From:Solid Earth (Vol. 10, Issue 3) Peer-Reviewed
Long-term measurements of volcanic gas emissions conducted during the last decade suggest that under certain conditions the magnitude or chemical composition of volcanic emissions exhibits periodic variations with a...

From:Atmospheric Chemistry and Physics (Vol. 21, Issue 12) Peer-ReviewedMasaya (Nicaragua, 12.0.sup." N, 86.2.sup." W; 635 m a.s.l.) is one of the few volcanoes hosting a lava lake, today. This study has two foci: (1) discussing the state of the art of long-term SO.sub.2 emission flux...

The carbon isotopic signature ([delta].sup.13 CH.sub.4) of several methane sources in Germany (around Heidelberg and in North Rhine-Westphalia) were characterised. Mobile measurements of the plume of CH.sub.4 sources...
