An analysis of diurnal cycles in the mass of ambient aerosols derived from biomass burning and agro-industry
(2013-08-16)
Strong diurnal cycles in ambient aerosol mass were observed in a rural region of Southeast Brazil where the trace composition of the lower troposphere is governed mainly by emissions from agro-industry. An optical particle ...
Aerosols monitoring in Rio Claro, Brazil: Using lidar and air pollution analyzers
(2011-04-26)
Brazil has an important role in the biomass burning aerosol activity. During the Dry Season (June-September) of 2009 an aerosol profiling campaign was carried out using a backscattering and Raman lidar system in Rio Claro-SP, ...
Influence of Intensive Agriculture on Dry Deposition of Aerosol Nutrients
(Soc Brasileira Quimica, 2010-01-01)
A procedure is presented for quantification of sources contributing to atmospheric aerosol chemical nutrient concentrations and dry deposition fluxes. Source apportionment using principal component analysis (PCA) and ...
A case study of the direct radiative effect of biomass burning aerosols on precipitation in the Eastern Amazon
(ELSEVIER SCIENCE INC, 2009)
Numerical experiments with the Brazilian additions to the Regional Atmospheric Modeling System were performed with two nested grids (50 and 10 km horizontal resolution, respectively) with and without the effect of biomass ...
Characterization of atmospheric aerosols in the city of So Paulo, Brazil: comparisons between polluted and unpolluted periods
(SPRINGERDORDRECHT, 2012)
The objective of this study was to determine the size and composition of atmospheric aerosols in the downtown area of the city of So Paulo, Brazil, for a polluted and an unpolluted period. Aerosols were sampled with a ...
Retrieving the relative contribution of aerosol types from single particle analysis and radiation measurements and calculations: A comparison of two independent approaches
(Elsevier, 2013-06)
The main purpose of this work is to determine the relative contribution of different types of aerosols at an urban site by using two independent approaches: individual particle analysis, and radiative transfer calculations ...
