Researchers at the University of Arkansas have established a link between climate patterns in the Amazon and large parts of North and South America using a newly developed tree-ring chronolo...
Emission and dry deposition of accumulation mode particles in the Amazon Basin
mode particles the Amazon Basin
2010/11/29
Size-resolved vertical aerosol number fluxes of particles in the diameter range 0.25–2.5 μm were measured with the eddy covariance method from a 53 m high tower over the Amazon rain forest, 60 km NNW ...
Impact of Manaus City on the Amazon Green Ocean atmosphere: ozone production, precursor sensitivity and aerosol load
Manaus City the Amazon Green Ocean atmosphere ozone production precursor sensitivity aerosol load
2010/10/11
We used a Single Column Chemistry and Transport Model (SCM) to infer the urban pollution emission fluxes of Manaus City, implying observed mixing ratios of CO, NOx and VOC. The model can reproduce the...
Transport of North African dust from the Bodélé depression to the Amazon Basin: a case study
North African dust the Bodélé depression the Amazon Basin

In the rainy season in Rondônia, convection in low-level westerly flows with low aerosol content resembles oceanic convection with precipitation from warm rain processes and little electrificati...
Direct measurements of the effect of biomass burning over the Amazon on the atmospheric temperature profile
biomass burning Amazon atmospheric temperature profile
2009/11/19
Aerosols suspended in the atmosphere interact with solar radiation and clouds, thus change the radiation energy fluxes in the atmospheric column. In this paper we measure changes in the atmospheric te...
