Influence of Regional Transport Mechanisms on the Fingerprint of Biomass-Burning Aerosols in Buenos Aires

Autor: Ana G. Ulke

Publikováno v: Advances in Meteorology, Vol 2019 (2019)

The study focuses on the transport of aerosol particles resulting from biomass burning in central South America towards the megacity of Buenos Aires by the South American Low-Level Jet. In particular, the cases are studied in which the exit area of t

Aerosol properties and meteorological conditions in the city of Buenos Aires, Argentina, during the resuspension of volcanic ash from the Puyehue-Cordón Caulle eruption

Autor: Darrel Baumgardner, Graciela B. Raga, Ana G. Ulke, Marcela María Torres Brizuela

Publikováno v: Natural Hazards and Earth System Sciences, Vol 16, Iss 9, Pp 2159-2175 (2016)

The eruption in June 2011 of the Puyehue-Cordón Caulle Volcanic Complex in Chile impacted air traffic around the Southern Hemisphere for several months after the initial ash emissions. The ash deposited in vast areas of the Patagonian Steppe was sub

The objective of this exploratory work is to test the hypothesis that South American populations of Ophioglossum reticulatum L. derive from Africa. Spores cross the Atlantic transported by wind and arrive in South America in recurrent migration. Thre

The environmental impact of the Puyehue–Cordon Caulle 2011 volcanic eruption on Buenos Aires

Autor: Beata Kucienska, M. Torres Brizuela, Graciela B. Raga, Ana G. Ulke, Darrel Baumgardner

Publikováno v: Natural Hazards and Earth System Sciences, Vol 13, Iss 9, Pp 2319-2330 (2013)

On 4 June 2011, the volcanic complex Puyehue–Cordon Caulle located in the Chilean Andes erupted, producing a plume of gases and particles that eventually circled the Southern Hemisphere, disrupting air travel and depositing ash in large quantities.

Factors controlling sea salt abundances in the urban atmosphere of a coastal South American megacity

Autor: Ana G. Ulke, Patricia Smichowski, Marina Dos Santos, Laura Dawidowski, Darío Gómez

Publikováno v: Atmospheric Environment. 59:483-491

The South Atlantic oceanic influence in the ambient air of Buenos Aires was studied on the basis of the measured concentrations of Cl − , Mg 2+ and Na + , as chemical markers of marine aerosols. A total of 113 fine (PM 2.5 ) and 113 coarse (PM 2.5�

Modeling urban air pollution in São Paulo, Brazil: sensitivity of model predicted concentrations to different turbulence parameterizations

Autor: Ana G. Ulke, M. Fátima Andrade

Publikováno v: Atmospheric Environment. 35:1747-1763

Production and transport of urban air pollution were studied at Sao Paulo, Brazil, due to the importance of the megacity as source of pollutants and the flow pattern and topography of the region. An Eulerian air quality model was applied. An improved
