Four Years of Atmospheric Boundary Layer Height Retrievals Using COSMIC-2 Satel...
Garnés-Morales, Ginés; Costa, Maria João; Bravo-Aranda, Juan Antonio; Granados-Muñoz, Maria José; Salgueiro, Vanda; Abril-Gago, JesusThis work aimed to study the atmospheric boundary layer height (ABLH) from COSMIC-2 refractivity data, endeavoring to refine existing ABLH detection algorithms and scrutinize the resulting spatial and seasonal distributions. Through validation analyses involving different ground-based methodologies (involving data from lidar, ceilometer, microwave radiometers, and radiosondes), the optimal ABLH determination re...
Fine and coarse dust radiative impact during an intense Saharan dust outbreak o...
López-Cayuela, M.A.; Córdoba-Jabonero, C.; Sicard, M.; Abril-Gago, J.; Salgueiro, Vanda; Comerón, A.; Granados-Muñoz, M.J.; Costa, Maria JoãoMineral dust has a key role in the Earth’s radiative balance, and it has become significant over the Iberian Peninsula (IP), where Saharan dust outbreaks have seemed to increase in frequency and intensity. This study quantifies the dust direct radiative effect (DRE) in the short-wave range (SW) during an intense persistent springtime dust episode over the IP. In particular, the vertical distribution of dust opt...
Large-Scale Network-Based Observations of a Saharan Dust Event across the Europ...
Papanikolaou, Christina-Anna; Papayannis, Alexandros; Gidarakou, Marilena; Abdullaev, Sabur F.; Ajtai, Nicolae; Baars, Holger; Balis, DimitrisBetween 14 March and 21 April 2022, an extensive investigation of an extraordinary Saharan dust intrusion over Europe was performed based on lidar measurements obtained by the European Aerosol Research Lidar Network (EARLINET). The dust episode was divided into two distinct periods, one in March and one in April, characterized by different dust transport paths. The dust aerosol layers were studied over 18 EARLI...

Monthly Convective Boundary Layer Height Study over Brazil Using Radiosonde, ER...
de Arruda Moreira, Gregori; Pérez Herrera, María Jesús; Garnés Morales, Ginés; Costa, Maria João; Cacheffo, Alexandre; Carbone, SamaraAlthough the atmospheric boundary layer height (ABLH) is a highly relevant parameter for various meteorological studies, the analysis of its behavior remains undersampled in South America, especially in Brazil. In this context, this work presents a monthly characterization of the ABLH during the convective period (Convective Boundary Layer Height-CBLH) using radiosonde data and a comparison between the monthly ...

Oliveira, Rui; Caldeira, Bento; Bortoli, Daniele; Guerrero-Rascado, Juan; Costa, Maria João; Bezzeghoud, Mourad; Salgueiro, VandaA publicação do Livro de Resumos Estendidos da 11a Assembleia Luso-Espanhola de Geodesia e Geofísica (ALEGG 2024) que decorreu na Universidade de Évora, de 24 a 27 de junho de 2024, reuniu investigadores de referência para a partilha de resultados nas mais variadas disciplinas. A ALEGG 2024 representou um momento crucial para a comunidade científica luso-espanhola, promovendo a partilha de conhecimentos, a disc...
Climate Effect on Morphological Traits and Polyphenolic Composition of Red Wine...
Rouxinol, Maria Inês; Martins, Maria Rosário; Salgueiro, Vanda; Costa, Maria João; Barroso, João; Rato, Ana ElisaWine quality is determined by the development of grape maturation, which is highly dependent on climate variations. Extreme weather events are becoming more common, which will affect the productivity and quality of grapes and wine. Grape development depends on many factors, including weather, and extreme events will influence berry size, skin thickness and the development of some key compounds, such as phenolic...
Fire-Pollutant-Atmosphere Components and Its Impact on Mortality in Portugal Du...
Duarte, Ediclê de Souza Fernandes; Salgueiro, Vanda; Costa, Maria João; Lucio, Paulo Sérgio; Potes, Miguel; Bortoli, Daniele; Salgado, RuiThis study analyzed fire-pollutant-meteorological variables and their impact on cardio-respiratory mortality in Portugal during wildfire season. Data of burned area, particulate matter with a diameter of 10 or 2.5 μm (μm) or less (PM10, PM2.5), carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), temperature, relative humidity, wind speed, aerosol optical depth and mortality rates of Circulatory System Dis...
Pollutant-meteorological factors and cardio-respiratory mortality in Portugal: ...
Duarte, Ediclê de Souza Fernandes; Lucio, Paulo Sérgio; Costa, Maria João; Salgueiro, Vanda; Salgado, Rui; Potes, Miguel; Hoelzemann, Judith J.Seasonal variations in cardiorespiratory diseases may be influenced by air pollution and meteorological factors. This work aims to highlight the relevance of a complete seasonal characterization of the pollutant-meteorological factors and cardio-respiratory mortality in Portugal and the relationships between health outcomes and environmental risk factors. To this end, air pollution and meteorological variables ...
