Multiscale Modeling of Convection and Pollutant Transport Associated with Volcanic Eruption and Lava Flow: Application to the April 2007 Eruption of the Piton de la Fournaise (Reun...
Published 2021-04-01“…This local modification of the wind flow strongly impacts the organization of the volcanic convection (injection height) and the regional transport of the sulfur dioxide emitted at the vent. These results show that explicitly solving volcanic activity/atmosphere complex interactions provides realistic forecasts of induced pollution.…”

Soot and SO[subscript 2] contribution to the supersites in the MILAGRO campaign from elevated flares in the Tula Refinery
Published 2013“…The flame of a representative sour gas flare is modeled with a CFD combustion code in order to estimate emission rates of combustion by-products of interest for air quality: acetylene, ethylene, nitrogen oxides, carbon monoxide, soot and sulfur dioxide. The emission rates of NO[subscript 2] and SO[subscript 2] were compared with measurements obtained at Tula as part of MILAGRO field campaign. …”

Intercontinental influence of NO[subscript x] and CO emissions on particulate matter air quality
Published 2015“…Anthropogenic emissions of nitrogen oxides (NO[subscript x] ≡ NO + NO[subscript 2]) and carbon monoxide (CO) affect particulate matter (PM) air quality on an intercontinental scale by changing background concentrations of oxidants (OH, ozone, H[subscript 2]O[subscript 2]) and thus increasing the oxidation rate of sulfur dioxide (SO[subscript 2]) to sulfate and NOx to nitrate. …”

Comprehensive analysis of combustion behavior, kinetics, and gas emissions of fungus bran biofuel through torrefaction pretreatment and polypropylene addition
Published 2024“…Additionally, the torrefaction process also increased biomass calcium content, which resulted in the effective reduction of sulfur dioxide (SO2) emissions. The incorporation of PP also demonstrated superior biomass binding capabilities and amplified pellet quality, when combined with co-torrefaction. …”

Magma storage, transport and degassing during the 2008-10 summit eruption at Kilauea Volcano, Hawai'i
Published 2013“…The aim of this work was to test the hypothesis that gases emitted from a summit lava lake will be rich in carbon dioxide (CO) and similar to those measured during the persistent lava lake activity in the early 20th century at Kīlauea Volcano (Gerlach and Graeber, 1985). We measured the sulfur dioxide (SO) and CO concentrations in the gas plume from Halema'uma'u using electrochemical and non-dispersive infrared sensors during April 2009. …”
