Trends in land cover and in pollen concentration of Quercus genus in Alentejo, ...
Galveias, Ana; Duarte, Ediclê; Raposo, Mauro; Costa, Maria João; Costa, Ana; Antunes, CéliaMediterranean forests dominated by Quercus species are of great ecological and economic value. The Quercus pollen season, peaking in April, varies in concentration due to geographical and climatic factors and has a remarkable allergenic potential. This study investigates Quercus trends in the Alentejo region of Portugal and examines the influence of meteorological parameters on DPC, PSD and SPIn, as well as the...
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...
Hydrometeorological dataset (2018–2023) from the largest Portuguese reservoir: ...
Rodrigues, Gonçalo; Purificação, Carolina; Potes, Miguel; Costa, Maria João; Salgado, RuiThe databases provided for two meteorological stations installed in the Alqueva reservoir (the largest artificial lake in Europe), one located on a floating platform and the other on the shore (approximately 1 km away in a straight line), cover a period of 6 years, from 2018 to 2023. The data available are, the hourly accumulated precipitation as well as the hourly averages of surface water temperature (0.25 m ...
Moisture Content Vegetation Seasonal Variability Based on a Multiscale Remote S...
Santos, Filippe; Rodrigues, Gonçalo; Potes, Miguel; Couto, Flavio; Costa, Maria João; Dias, Susana; Monteiro, Maria José; Ribeiro, Nuno; Salgado, RuiWater content is one of the most critical characteristics in plant physiological development. Therefore, this information is a crucial factor in determining the water stress conditions of vegetation, which is essential for assessing the wildfire risk and land management decision-making. Remote sensing can be vital for obtaining information over large, limited access areas with global coverage. This is important...
Assessment of Water Surface Reflectance and Optical Water Types Over Two Decade...
Rodrigues, Gonçalo; Potes, Miguel; Costa, Maria JoãoThis study focuses on comparing surface reflectances and optical water types (OWTs) obtained in Alqueva reservoir, located in the Alentejo region (Portugal), over a period of two decades (2003–2022) using four datasets: the moderate resolution imaging spectroradiometer (MODIS), themedium-resolution imaging spectrometer, the ocean and land color instrument aboard Sentinel-3, and the multispectral instrument aboa...
Impact of monthly air pollution and weather conditions on cardiorespiratory mor...
Duarte, Ediclê de Souza Fernandes; Lucio, Paulo Sérgio; Lígia, Henriques-Rodrigues; Costa, Maria JoãoThis study analyses cardiorespiratory mortality rates (CARDIO) and their association with air pollutants - particulate matter with aerodynamic diameters lower of equal to 10 or 2.5 (μm) (PM10, PM2.5), carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3) - and meteorological variables (temperature, humidity, wind speed, direction) in the Lisbon (LMA) and Porto (PMA) metropolitan areas from 2011 to 2020. Mont...
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...

Tools for managing metal contaminated areas: multidisciplinary approach to deve...
Oliveira, Rui Jorge; Caldeira, Bento; Palma, Patrícia; Costa, Maria João; Fialho, AnaThis work aims to develop an environmental management model specifically designed for mining areas that have been contaminated by toxic metals. A sustainable management model is suggested to be established, utilizing a combination of developed tools. This model will provide tools and strategies to effectively manage and mitigate the environmental impact of such contamination, with the goal of promoting an incre...
Instrumento de gestão de áreas contaminadas por metais combinando dados de Quím...
Oliveira, Rui Jorge; Caldeira, Bento; Palma, Patrícia; Costa, Maria João; Fialho, AnaO Projeto INCOME propõe a criação de um modelo de gestão ambiental para áreas mineiras contaminadas por metais tóxicos. Este modelo integra os resultados da aplicação de um conjunto de métodos analíticos e instrumentos de monitorização de áreas contaminadas, como análises biofísicas, química do solo e da água (parâmetros de qualidade e quantificação de metais potencialmente tóxicos em amostras de solo e água), ...
