The 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 ...
Water 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...
This 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...
The study of soils contaminated by heavy metals (HMs) is a hard task that implies the collecting of soil samples in an area representative of the contaminated space. For example, for water samples, the law requires the creation of a study grid with 5 ha spacing. Considering this spacing requirement, to the soil from the São Domingos Mine, that have an area of approximately 2000 ha, we need to collect 400 sample...
O bem-estar animal é uma das condições que, concretizadas, colocam a humanidade mais perto de um estilo de vida mais sustentável e do usufruto de um planeta mais saudável. A sua importância é inclusive reconhecida por organizações como a ONU, estando patente em 2 dos 17 Objetivos de Desenvolvimento Sustentável da Agenda 2030 (objetivos 14 e 15). No entanto até que ponto a importância da causa animal é reconheci...
INTRODUCTION: Fenestrated and branched stent graft technology has come a long way over the past few years, enabling the treatment of complex juxtarenal aneurysms, thoracoabdominal aneurysms, and arch pathologies. Many innovations have been developed, namely device and delivery optimization and technical tricks. These concepts have proven to work well when there is sufficient time to plan and manufacture a custo...
Old and abandoned mines are testimonials of ancient industrial activities, and as such, they are able to convey environmental concerns. A multidisciplinary approach combining ground measurements—i.e., portable X-ray fluorescence and optical spectroradiometry—with airborne multispectral images—i.e., Sentinel-2 and unmanned aerial vehicles—was conducted to define a baseline for the characterization of areas that ...

O Projeto ALOP teve início formal a 25 de Maio de 2016 e terminou a 31 de dezembro de 2019. Neste relatório final procuramos dar conta das atividades efetuadas e principalmente dos resultados obtidos. A tarefa está facilitada pois o projeto, em conjunto com as sinergias geradas com outros projetos e as colaborações nacionais e internacionais dos vários membros da equipa permitiram a publicação de um invejável n...
