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. ...
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 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 ...
Estimation of atmospheric total organic carbon (TOC) - Paving the path towards carbon budget closure
(Copernicus GmbH, 2019)
© Author(s) 2019. The atmosphere contains a rich variety of reactive organic compounds, including gaseous volatile organic carbon (VOCs), carbonaceous aerosols, and other organic compounds at varying volatility. Here we ...
Estimation of C2n based on scintillation of fixed targets imaged through atmospheric turbulence
(Optical Society Of America, 2015-12)
We define a pixel-based scintillation index for dynamic incoherent imaging of fixed high-contrast targets through atmospheric turbulence. We propose a simple setup to study this parameter varying the C2n constant in ...
Temporal correlations imaging fixed targets through turbulence
(Optical Society of America, 2016-06)
We study the temporal correlations from dynamic imaging through turbulence using incoherent light from fixed highcontrast targets. We conduct our experiment in controlled laboratory conditions using several values of the ...
STUDIES ON THE RELATIONSHIP BETWEEN THE PATHOGENICITY OF PARACOCCIDIOIDES-BRASILIENSIS IN MICE AND ITS GROWTH-RATE UNDER DIFFERENT OXYGEN ATMOSPHERES
(Kluwer Academic Publ, 1991-05-01)
We performed comparative studies of the pathogenicity of six strains of Paracoccidioides brasiliensis (Bt-9, Bt-4, Pb-9, Pb-18, Bt-7 and B-1183) for young adult male ddY mice and growth rate of each strain under different ...
A time series sequestration and storage model of atmospheric carbon dioxide
(Elsevier B.V., 2014-01-24)
One of the main challenges of environment planning is to identify a model that connects all factors that determine the carbon cycle, that is: ocean-terrestrial ecosystem-anthropogenic emissions-atmosphere. Basic principle ...
Atmospheric correction issues for retrieving total suspended matter concentrations in inland waters using OLI/Landsat-8 image
(Elsevier B.V., 2017-05-01)
The atmospheric effects that influence on the signal registered by remote sensors might be minimized in order to provide reliable spectral information. In aquatic systems, the application of atmospheric correction aims to ...
Host trait combinations drive abundance and canopy distribution of atmospheric bromeliad assemblages
(Oxford Univ Press, 2016-01-01)
Epiphytes are strongly dependent on the conditions created by their host's traits and a certain degree of specificity is expected between them, even if these species are largely abundant in a series of tree hosts of a given ...
