Combining hectometric and decametric satellite observations to provide near real time decametric FAPAR product
2017
Abstract A wide range of ecological, agricultural, hydrological and meteorological applications at local to regional scales requires decametric biophysical data. However, before the launch of SENTINEL-2A, only few decametric products are produced and most of them remain limited by the small number of available observations, mostly due to a moderate revisit frequency combined with cloud occurrence. Conversely, kilometric and hectometric biophysical products are now widely available with almost complete and continuous coverage, but the associated spatial resolution limits the application over heterogeneous landscapes. The objective of this study is to combine unfrequent decametric spatial res…
High Arctic aircraft measurements characterising black carbon vertical variability in spring and summer
2019
The vertical distribution of black carbon (BC) particles in the Arctic atmosphere is one of the key parameters controlling their radiative forcing and thus role in Arctic climate change. This work investigates the presence and properties of these light-absorbing aerosols over the High Canadian Arctic (>70∘ N). Airborne campaigns were performed as part of the NETCARE project (Network on Climate and Aerosols: Addressing Key Uncertainties in Remote Canadian Environments) and provided insights into the variability of the vertical distributions of BC particles in summer 2014 and spring 2015. The observation periods covered evolutions of cyclonic disturbances at the polar front, which f…

Citizens' Political Discourses on Climate Change and Vaccines
2022
The main objective of this chapter is to compare the political discourses of Polish and Spanish citizens on science issues such as vaccines and climate change expressed by the citizens participating in the public consultations held in València (Spain) and Łódź (Poland) during the autumn of 2019. As the general elections were held very close to the public consultations in both countries, it was expected that there would be references to election campaigns, political parties, or public policymaking during the debates. Then, those statements explicitly expressing political views on climate change and vaccines were selected from the debate transcripts before applying five specific frames and va…

Trends in EU Energy Policy 1995–2007
2011
Today, climate change and a significant increase in energy consumption are considered to be the two greatest global challenges facing the energy world (e.g., Hasselmann et al. 2003: 1923; IPCC 2007; Kara 2007: 5; Karl and Trenberth 2003: 1719). In addition to the scientific community having a common understanding about these two issues relating to each other, the political decision makers also need to acknowledge it and start building a framework around it – with the same longterm targets. On the EU-level, climate change concerns were already manifested in the White Paper on Energy Policy for the European Union in 1995. The development of the EU’s common energy policy is also the result of …
Chemical, biochemical and cellular responses in the digestive gland of the mussel Mytilus galloprovincialis from the Spanish Mediterranean coast.
2013
Mussels (Mytilus galloprovincialis) were sampled in March 1996 from five stations along the Western Mediterranean coast (Barcelona, Ebro Delta, Alboraya, Cullera, Denia) corresponding to urban, industrial and agricultural areas. Different biochemical and cellular markers were determined in the mussels in order to assess the effects and/or exposure to pollutants. The cytochrome P450 system, acetylcholinesterase and metallothioneins were among the biochemical markers selected for the study. Histochemical analysis of ß-glucuronidase and catalase activity were performed as marker enzymes for lysosomes and peroxisomes. Chemical analyses indicated that mussels from Barcelona and Denia as highly e…

Abstract. As part of the Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) project, an airborne campaign was designed to measure a large range of atmospheric constituents, focusing on the effect of anthropogenic emissions on regional climate. The presented study details results of the French ATR42 research aircraft, which aimed to characterize gas-phase, aerosol and cloud properties in the region during the field campaign carried out in June/July 2016 in combination with the German Falcon 20 and the British Twin Otter aircraft. The aircraft flight paths covered large areas of Benin, Togo, Ghana and Côte d'Ivoire, focusing on emissions from large urban conurbations such …
Monitoring and Origin of Polycyclic Aromatic Hydrocarbons (PAHs) in Effluents from a Surface Treatment Industry
2017
In Europe, polycyclic aromatic hydrocarbons (PAHs) are a source of concern due to their toxic effects and are considered as priority pollutants by water authorities. In this study, we reported the ...
THE IMPACT OF TRAFFIC RELATED POLLUTION ON AIR QUALITY IN SIBIU REGION
2015
Urban areas represent the main zones of anthropogenic emissions and, at the same time, includes the largest number of population exposed to air pollution. Data related to traffic hot spots locations in Sibiu urban areas are presented and discussed in this paper. It is important to assess the impact of changing climate conditions and concentration of pollutants, these aspects are of special interest because of high and increasing population of urban regions exposed to consequences of climate change and air pollution. Paper tackling the problem of traffic related pollution and especially PM10 fraction as a novel research. No other research were previously done in Sibiu region emphasising part…
