Assessment of neutral atmospheric delay predictions based on the temporal resolution of an atmospheric model
(2020-01-01)
In Global Navigation Satellite Systems (GNSS), the effects of neutral atmosphere in electromagnetic signal propagation impacts directly on the quality of the final estimated position, leading to errors in the metric order. ...
Lower and middle atmosphere and ozone layer responses to solar variation
(Cambridge University Press, 2010-02)
Global warming in the troposphere and the decrease of stratospheric ozone concentration has become a major concern to the scientific community. The increase in greenhouse gases and aerosols concentration is believed to be ...
Effects of atmospheric oscillations on infectious diseases: The case of chagas disease in Chile
(Fundacao Oswaldo Cruz, 2019)
Effect of atmosphere and dopants on sintering of SnO2
(2002-12-01)
Tin oxide is an n type semiconductor material with a high covalent behavior. Mass transport in this oxide depends on the surface state promoted by atmosphere or by the solid solution of aliovalent oxide doping. The sintering ...
Optimization of the atmospheric pollution monitoring network at Santiago de Chile
(Elsevier Ltd, 2003)
Environmental pollution is a problem affecting many cities in our planet. Santiago de Chile is one with the worst indices. Because of that, local authorities implemented a few years ago an air quality monitoring network ...
Including the sub-grid scale plume rise of vegetation fires in low resolution atmospheric transport models
(2007-08-03)
We describe and begin to evaluate a parameterization to include the vertical transport of hot gases and particles emitted from biomass burning in low resolution atmospheric-chemistry transport models. This sub-grid transport ...

Effect of atmospheric pollution on the respiratory system
(1998)
Santiago de Chile has a high level of air pollution with ozone (O3), carbon monoxide (CO) and particles equal or smaller than 10 μm (PM10) usually exceeding the accepted standards. This situation should be noxious for the ...
Effect of atmosphere on the sintering and grain growth of tin oxide
(1999-12-01)
High purity SnO 2 powder (>99.9%) was compacted in cylindrical pellets and sintered in atmospheres of dry argon, argon with water vapor, oxygen and CO 2 using 10 °C/min up to 1200 °C or isotherms in the range of 1000 to ...
