Relatório Final do projeto ALOP (ALT20-03-0145-FEDER-000004)

Salgado, Rui; Palma, Patrícia; Morais, M. Manuela; Almeida, Adelaide; Alvarenga, Paula; Antunes, Célia; Aranha, Sergio; Bárias, Samuel; Barrenho, Joel

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...


Estimativa do potencial fotovoltaico no Sul de Portugal através de simulações d...

Pereira, Sara; Abreu, Edgar; Iakunin, Maksim; Canhoto, Paulo; Salgado, Rui

O objetivo deste trabalho é a geração de mapas de recurso solar e de po- tencial fotovoltaico (PV) para o Sul de Portugal. Estes mapas foram obtidos com base em simulações de um modelo de Previsão Numérica do Tempo (NWP) para um Ano Meteorológico Típico (TMY). Os TMYs reproduzem as estatísticas de longo prazo e consistem em 12 meses típicos concatenados. Para determinar um TMY para Évora foram usados dezasseis ...


Improved method for solar resource assessment using simulations from the numeri...

Pereira, Sara; Abreu, Edgar F.M.; Iakunin, Maksim; Canhoto, Paulo; Salgado, Rui

Numerical Weather Prediction (NWP) models tend to show significant errors to what solar radiation forecast is concerned, mainly due to difficulties with the correct parameterization of clouds, the usage of monthly-mean aerosol climatology, and the high computational effort associated to the detailed modeling of radiative transfer in the atmosphere. This is especially evident in the case of direct normal (DNI) a...


Lightning modelling in numerical weather prediction

Salgado, Rui; Couto, Flavio; Iakunin, Maksim; Pinto, Paulo; Viegas, Tânia; Pinty, Jean-Pierre

The explicit representation of the atmospheric electric field in numerical weather prediction models is a current challenge. This representation will allow a physically based lightning forecast. Present study aims to assess the performance of the Cloud ELectrification and Lightning Scheme (CELLS) [1] coupled to the Meso-NH atmospheric mesoscale research model [2] in simulating Cloud-to-Ground (CG) flashes. The ...

Palma, Patrícia; Penha, Alexandra Marchã; Novais, Maria Helena; Fialho, Sofia; Lima, Ana; Catarino, Adriana; Mourinha, Clarisse; Alvarenga, Paula

The Guadiana Basin is a transnational basin, presenting historical contamination with potentially toxic metals (PTM), which origin can be both natural and anthropogenic. This study explores the use of a set of observational, chemical and ecotoxicological assays with Heterocypris incongruens, Vibrio fischeri, Pseudokirchneriella subcapitata, Thamnocephalus platyurus, identifying the most sensitive to be included...


Water-Sediment Physicochemical Dynamics in a Large Reservoir in the Mediterrane...

Palma, Patrícia; Marchã Penha, Alexandra; Novais, Maria Helena; Fialho, Sofia; Lima, Alexandra; Mourinha, Clarisse; Alvarenga, Paula; Rosado, Anabela

Nowadays, the Mediterranean freshwater systems face the threat of water scarcity, along with multiple other stressors (e.g., organic and inorganic contamination, geomorphological alterations, invasive species), leading to the impairment of their ecosystem services. All these stressors have been speeding up, due to climate variability and land cover/ land use changes, turning them into a big challenge for the wa...

Lightning Prediction with a mesoscale atmospheric model

Salgado, Rui; Couto, Flavio; Iakunin, Maksim; Pinto, Paulo; Viegas, Tânia; Pinty, Jean-Pierre

Predicting the probability of lightning strikes, particularly under very hot weather, can be useful for assess the risk of natural ignitions. The present study aims to assess the performance of the Cloud Electrification and Lightning Scheme (CELLS) [1] coupled to the Meso-NH atmospheric mesoscale model [2] in simulating Cloud-to-Ground (CG) flashes. For this purpose, a simulation of a case study in which many l...

Pereira, Sara; Abreu, Edgar F.M.; Iakunin, Maksim; Cavaco, Afonso; Salgado, Rui; Canhoto, Paulo

In this work a method for regional solar resource assessment based on numerical weather prediction (NWP) and artificial neural network (ANN) models is presented. The method was developed using typical meteorological and solar radiation data and applied to the location of E ́vora, Portugal with the goal of assessing solar global horizontal (GHI) and direct normal (DNI) irradiations with 1.25 km of horizontal res...


Modelling dry thunderstorm environment during a wildfire episode in Portugal

Couto, Flavio; Iakunin, Maksim; Salgado, Rui; Pinto, Paulo; Viegas, Tânia; Pinty, Jean-Pierre

Under future climate uncertainties, a better understanding of wildfires is necessary both from physical and operational points of view, which are the goals of the CILIFO (Centro Ibérico para la Investigacion y Lucha contra Incendios Forestales) Interreg POCTEP project. Among several sources of fire ignition, lightnings are the main natural source of wildfires and an important contributor to burned areas in many...
