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 ...
Beam wandering statistics of twin thin laser beam propagation under generalized atmospheric conditions
(Optical Society of America, 2012-11-29)
Under the Geometrics Optics approximation is possible to estimate the covariance between the displacements of two thin beams after they have propagated through a turbulent medium. Previous works have concentrated in long ...
Warm-season precipitation drivers in northeastern Argentina: Diurnal cycle of the atmospheric moisture balance and land–atmosphere coupling
(John Wiley & Sons Ltd, 2020-07)
Southeastern South America is influenced by moisture transport from lower latitudes, sustainsintense convective storms and is a land-atmosphere coupling hotspot, but the interconnectionbetween these processes is still not ...
Improving the Ni I atomic model for solar and stellar atmospheric models
(IOP Publishing, 2013-05-10)
Neutral nickel (Ni I) is abundant in the solar atmosphere and is one of the important elements that contribute to the emission and absorption of radiation in the spectral range between 1900 and 3900 Å. Previously, the Solar ...
Relationship between sea surface temperature anomalies in the Southwestern Atlantic Continental Shelf and atmospheric variability on intraseasonal timescales
(Springer-v D I Verlag Gmbh, 2022-09)
The intraseasonal (IS) variability of the sea surface temperature (SST) in the Southwestern Atlantic Continental Shelf (SWACS, 45–33° S—70–50° W), and its relationship with that in the atmosphere, was studied for the austral ...
Land-Atmosphere Coupling Sensitivity to GCMs Resolution: A Multimodel Assessment of Local and Remote Processes in the Sahel Hot Spot
(Amer Meteorological Soc, 2020-11)
Land–atmosphere interactions are often interpreted as local effects, whereby the soil state drives local atmospheric conditions and feedbacks originate. However, nonlocal mechanisms can significantly modulate land–atmosphere ...
Response of the lower atmosphere to intense geomagnetic storms
(Elsevier, 2011-09)
In this short paper we examine the possible connection between atmospheric parameters measured at low and middle altitudes and geomagnetic storms occurred in 2000 and 2003. For that, from a chain of stations located near ...
Atmospheric corrosion of reference metals in Antarctic sites
(Elsevier Science, 2004-12)
This paper presenta the results obtained at three Antarctic test sites participating in the "Ibero-American Map of Atmospheric Corrosiveness" (MICAT), a project on atmospheric corrosion carried out during the period 1988-1994 ...
Effect of atmospheric pollutants on the corrosion of high power electrical conductors: Part 1. Aluminium and AA6201 alloy
(Pergamon-Elsevier Science Ltd, 2006-10)
The aim of this study was to evaluate the joint effect of marine and industrial pollutants on the atmospheric corrosion of aluminium and its AA6201 alloy. Weight loss was determined after 4, 11, 16 and 24 months exposure ...
Atmospheric degradation of industrial fluorinated acrylates and methacrylates with Cl atoms at atmospheric pressure and 298 K
(Pergamon-Elsevier Science Ltd, 2018-04)
The gas-phase reaction of Cl atom with 2,2,2-trifluoroethylacrylate (k1), 1,1,1,3,3,3-hexafluoroisopropylacrylate (k2), 2,2,2-trifluoroethylmethacrylate (k3) and 1,1,1,3,3,3-hexafluoroisopropylmethacrylate (k4), have been ...
