Simulation of Long-Term Changes of the Equilibrium Line Altitude in the Central Chilean Andes Mountains Derived From Atmospheric Variables During the 1958-2018 Period
(2019)
Interannual variability and trends of the Equilibrium Line Altitude (ELA) in the Andes mountains can be modeled using an empirical relationship between the annual average of the 0 degrees C isotherm altitude (ZIA) and the ...
Modeling study of biomass burning plumes and their impact on urban air quality; a case study of Santiago de Chile
(2017)
On January 4, 2014, during the summer period in South America, an intense forest and dry pasture wildfire occurred nearby the city of Santiago de Chile. On that day the biomass-burning plume was transported by low-intensity ...
Measurements from ground and balloons during APE-GAIA - A polar ozone library
(Elsevier, 2005-12)
Many long-term monitoring sites in Antarctic regions, which deploy ground-based stratospheric remote sensors and fly radiosondes or ozonesondes on balloons, supported the Airborne Polar Experiment in September and October ...
Total column water vapor estimation over land using radiometer data from SAC-D/Aquarius
(Elsevier, 2018-02)
The aim of this study is retrieving atmospheric total column water vapor (CWV) over land surfaces using a microwave radiometer (MWR) onboard the Scientific Argentine Satellite (SAC-D/Aquarius). To research this goal, a ...
Dinâmica e morfologia da tropopausa sobre a região de NatalRN utilizando dados de radiossondagens do Centro de Lançamento da Barreira do Inferno
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIAS CLIMÁTICAS, 2020-05-14)
The terrestrial equatorial tropopause is generally analyzed as a region of modest temperature variations and defined only as an interface between the troposphere and the
stratosphere. However, recent works have suggested ...
Evaluation of the WRF model configuration for zonda wind events in a complex terrain
(2015)
Abstract: The Weather Research and Forecasting (WRF) Model was used to simulate two mesoscale events of Zonda winds that occurred in August 2010 and April 2011. The model was applied on a complex terrain area of high ...
Validity and behaviour of tropospheric gradients estimated by GPS in Corsica
(Elsevier B.V., 2015-01-01)
Estimation of tropospheric gradients in GNSS data processing is a well-known technique to improve positioning (e.g. Bar-Sever et al., 1998; Chen and Herring, 1997). More recently, several authors also focused on the ...
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 ...
Evidence of horizontal and vertical transport of water in the Southern Hemisphere tropical tropopause layer (TTL) from high-resolution balloon observations
(2016-09-29)
High-resolution in situ balloon measurements of water vapour, aerosol, methane and temperature in the upper tropical tropopause layer (TTL) and lower stratosphere are used to evaluate the processes affecting the stratospheric ...
Estudo da camada limite interna térmica em condições de brisa do mar, utilizando diferentes parametrizações: Aplicação do modelo wrf na região da grande vitória
(2016-01-01)
In the present study, the physical parameterizations of the Weather Research and Forecasting (WRF) model are verified for making accurate inferences about the dynamics of the Thermal Internal Boundary Layer (TIBL) generated ...
