Effects of atmospheric stability conditions on the pollutants dispersion near roads using CFD
This study quantifies the effects of atmospheric stability conditions on the concentration of atmospheric pollutants near roads. We used as a base case scenario the resulting concentrations obtained solving numerically the ...
RETROGRADE AND DIRECT POWERED AERO-GRAVITY-ASSIST TRAJECTORIES AROUND MARS
(Univ Nacional Autonoma Mexico, Inst De Astronomia, 2018-04-01)
A Gravity-Assist maneuver is used to reduce fuel consumption and/or trip times in interplanetary missions. It is based in a close approach of a spacecraft to a celestial body. Missions like Voyager and Ulysses used this ...

Effect of thermal treatment under oxygen atmosphere on the superconducting properties of RuSr2GdCu2O8
(2006-12-01)
The discovery of the spatial uniform coexistence of superconductivity and ferromagnetism in rutheno-cuprates, RuSr2GdCu2O8 (Ru-1212), has spurred an extraordinary development in the study of the competition between magnetism ...
Using vertically pointing broad beam to measure atmospheric aspect sensitivity of VHF radar echoes
(1989)
Conventionally, atmospheric aspect sensitivlty of VHF radar echoes is measured using a narrow beam radar in order to avoid the complications due to broad beam effects. However, in this study, a new technique using beam ...
The effect of buildings on atmospheric turbulence in open spaces in Western Sao Paulo State, Brazil
(Univ Politecnica Valencia, 2018-01-01)
This paper seeks to identify a pattern of air turbulence that reflects the effect of buildings on air turbulence characteristics measured in open spaces in Western Sao Paulo State, Brazil. Atmospheric turbulence was estimated ...
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 ...
50 years of synergy between space geodesy and meteorology: From a GNSS positioning error to precipitation nowcasting applications50 anos de sinergia entre geodésia espacial e meteorologia: Do erro no posicionamento GNSS a aplicações de previsão de precipitação de curtíssimo prazo
(2020-12-01)
The neutral atmosphere (or troposphere) causes refraction in radio frequency signals, which results in errors in Global Navigation Satellite Systems (GNSS) measurements. In meteorology, this effect can represent important ...
