1st Iberian Meeting on Aerosol Science and Technology - RICTA 2013 PROCEEDINGS BOOK
No full textThis Proceedings Book contains the conference communications (oral and poster)
received before the editing deadline and presented at the 1st Iberian Meeting on
Aerosol Science and Technology (RICTA 2013), which was held from 1-3 July 2013,
in Évora, Portugal.
The event was simultaneously the VI Reunión Española de Ciencia y Tecnología de
Aerosoles and the IV Summer School on Aerosol Science and Technology, in 2013
organized and hosted by the Geophysics Centre of the University of Évora (CGE)
with the collaboration of the Asociación Española de Ciencia y Tecnologia de los
Aerosoles (AECTA).
The Meeting, for the first time a Portuguese-Spanish Reunion on Aerosol Science,
gathered over 90 participants covering a wide range of aerosol science and
technology. As in previous editions of RECTA, the participation of young researchers
was especially welcome, with the organization of the 4th Summer School on Aerosol
Science and Technology and awards for the best poster and PhD thesis.
The editors would like to express their sincere gratitude to all the participants, in
particular, those who contributed to this book by submitting their papers to convey
the science discussed at RICTA 2013. Finally, we also thank the referees for their
valuable revision of these papers

Habitar en la órbita terrestre baja. Un estudio desde la óptica de la arquitectura
Get PDFLa tecnología y la arquitectura dan al ser humano la capacidad de habitar en los entornos más hostiles del planeta. A finales del siglo XX, la revolución tecnológica tras las dos guerras mundiales nos dio al fin la capacidad de colonizar la última frontera de nuestro planeta: la órbita terrestre baja. En este trabajo se analiza, desde un punto de vista interdisciplinar con énfasis en la arquitectura, lo que supone romper esa frontera. Las condiciones, los efectos, la evolución histórica de los hábitats orbitales, hasta llegar a la Estación Espacial Internacional. Este último y exitoso hábitat, objeto principal del estudio, nos proporciona en su diseño una herramienta analítica para desmenuzar los múltiples estratos que componen este tipo de habitabilidad extrema, Sumando al análisis la inventiva de la arquitectura terrestre, que históricamente ha sabido resolver problemáticas similares, estaremos en condiciones de proponer mejoras y arquitecturas habitables, más allá de la funcionalidad estricta que históricamente ha dominado el campo de la exploración espacial.Universidad de Granada.

Validación de datos de la Misión satelital Aeolus mediante lidars de superficie en dos estaciones de la Península Ibérica
Get PDFActualmente los sistemas globales de observación aún presentan una gran deficiencia
relacionada con las medidas del viento, lo que provoca que aún no se dispongan de
modelos de predicción de vientos realmente precisos y eficaces a escala global,
principalmente por la falta de perfiles en las regiones inaccesibles o menos habitadas. En
este contexto, la Agencia Espacial Europea está desarrollando la misión de Aeolus,
mediante la que se ha puesto en órbita un satélite capaz de cubrir todo el planeta y generar
los perfiles de vientos necesarios, junto con otras variables también importantes como
son los perfiles de coeficiente de retrodispersión y extinción de los componentes
atmosféricos. En general, durante la vida útil de los satélites, y especialmente durante las
primeras fases, es fundamental la calibración y validación de sus productos. El presente
estudio contribuye a este aspecto mediante un proceso de intercomparación de los perfiles
de coeficiente de retrodispersión de partículas determinados mediante ALADIN, el lidar
a bordo del satélite Aeolus, y lidars en superficie, para dos estaciones distintas de la
Península Ibérica pertenecientes a la red EARLINET: Évora (Portugal) y Granada
(España). En primer lugar, se realiza un estudio preliminar, y fundamental, de los datos
disponibles procurando garantizar que las medidas utilizadas tengan la calidad requerida.
Tras esto, se realiza la intercomparación de los perfiles mediante diferentes estadísticos
con los que obtener conclusiones acerca de la calibración y fiabilidad de los productos de
retrodispersión generados por la misión Aeolus.Universidad de Granada. Máster Universitario en Geofísica y Meteorología. (GEOMET). Curso 2019-202
Perfis de núcleos de gelo durante eventos de poeira do Sahara por combinação de técnicas de deteção remota ativa e passiva
Get PDFNesta dissertação, analisam-se perfis de retrodispersão, despolarização e núcleos de gelo, durante eventos de poeira, em diferentes condições de temperatura e diferentes quanti-dade de aerossol. Utilizam-se medidas de despolarização LIDAR (LIght Detection And Ranging), e utiliza-se um método computacional de vanguarda, o POLIPHON (POlarization-Lidar PHOto-meter Networking).
Começa-se por fazer uma revisão de conceitos relacionados com a radiação solar, e uma descrição das interações entre os aerossóis e a radiação e as nuvens, bem como da tecnologia aplicada para o presente estudo, do funcionamento de um sistema lidar. Avalia-se um evento de poeiras, que afetou grande parte da Península Ibérica. Determinam-se perfis de núcleos de gelo, e simulam-se os efeitos nesses perfis, se as temperaturas fossem consideravelmente infe-riores.
Nas conclusões, são analisados alguns dos resultados e é feita uma análise sobre quais seriam os efeitos sobre a formação de nuvens, considerando as prováveis alterações climáticas; Abstract:
In this dissertation, profiles of backscatter, depolarization ratios and ice nuclei are analyzed during dust events at different temperature conditions and different amounts of aerosol. Measurements of LIDAR (LIght Detection and Ranging) depolarization were used along with a state-of-the-art computational method, POLIPHON (POlarization-Lidar PHOtometer Networking).
It begins with a review of concepts related to solar radiation, and a description of the interactions aerosol-radiation and aerosol-clouds, as well as the technology applied to the present study, of the functioning of a LIDAR system. An event of dust that affected great part of the Iberian Peninsula is analyzed. Ice nuclei profiles are determined, and the effects on these profiles are simulated if temperatures are considerably lower.
As a conclusion, some of the results are studied and an analysis of the effects on the formation of clouds, considering the probable climate changes is made
Propagación de ondas de presión y detección sísmica del meteoroide de Granada 2016
Get PDFAcoustical signals detected by seismic stations could be used to determine the location of a wave source located in the atmosphere. We study the propagation of sound pressure waves through the atmosphere in order to understand the basis of the method that uses arrival times at seismic stations and a proper atmospheric model to estimate the so-called supracenter. We apply the method to the available data from the seismic records of the shock-wave produced by the terminal burst of a meteoroid that flew over the provinces of Granada and Jaén in 2016. We use astronomical data to fix the occurrence time of the fragmentation of the meteoroid, aiming to improve the estimated location of the event. We find the optimal location of the supracenter to be at approximately 38 km over Alcalá la Real, Jaén, at 37.4939º N, 3.9083º O.Universidad de Granada. Máster en Geofísica y Meteorología (GEOMET).
