Bias correction of dynamically downscaled precipitation to compute soil water deficit for explaining year-to-year variation of tree growth over north…
2017
This paper documents the accuracy of a post-correction method applied to precipitation regionalized by the Weather Research and Forecasting (WRF) Regional Climate Model (RCM) for improving simulated rainfall and feeding impact studies. The WRF simulation covers Burgundy (northeastern France) at a 8-km resolution and over a 20-year long period (1989–2008). Previous results show a strong deficiency of the WRF model for simulating precipitation, especially when convective processes are involved. In order to reduce such biases, a Quantile Mapping (QM) method is applied to WRF-simulated precipitation using the mesoscale atmospheric analyses system SAFRAN («Système d'Analyse Fournissant des Rense…
Intense magmatic degassing through the lake of Copahue volcano, 2013–2014
2015
Here we report on the first assessment of volatile fluxes from the hyperacid crater lake hosted within the summit crater of Copahue, a very active volcano on the Argentina-Chile border. Our observations were performed using a variety of in situ and remote sensing techniques during field campaigns in March 2013, when the crater hosted an active fumarole field, and in March 2014, when an acidic volcanic lake covered the fumarole field. In the latter campaign, we found that 566 to 1373 t d -1 of SO 2 were being emitted from the lake in a plume that appeared largely invisible. This, combined with our derived bulk plume composition, was converted into flux of other volcanic species (H 2 O ~ 1098…

The Messinian stromatolites of the Sierra del Colmenar (Western Mediterranean): facies characterization and sedimentological interpretation
2018
A representative outcrop of the Messinian stromatolites belonging to the Terminal Carbonate Complex unit, from the northern sector of the Bajo Segura basin (Caja de Ahorros del Mediterraneo section, Sierra del Colmenar, SE Spain) has been studied. Here, we present a detailed analysis of the architecture, external morphology, and internal morphology in order to reconstruct the environmental and palaeoecological conditions for their growth. The stromatolites macrostructure consists of a continuously doming type morphology (build up and sheets areas).These developed close to the coast and acted as a palaeogeographic barrier, reducing physical stress, channeling the erosive effect of water and …
Anche in Francia è un dilemma: accettare o no i petroldollari del Qatar? 150 milioni per le banlieue parigine
2013
Iniziano a indirizzarsi verso città europee forme di cooperazione internazionale alla rovescia: l'articolo parla dell'infuocato dibattito francese sull'opportunità di accettare finanziamenti dal Qatar per la micro-imprenditoria di soggetti svantaggiati che abitano nelle periferie di Parigi.
Actividad y territorio : la localización de la población extranjera en Barcelona
2005
Este texto analiza el papel selectivo del territorio en el asentamiento de la población de nacionalidad extranjera y, en especial, de la función de la ciudad de Barcelona como lugar de atracción, filtro y selección de esta población en el contexto de Cataluña. Con este objetivo, en primer lugar se describen las pautas de distribución espacial de la población extranjera en Cataluña, para posteriormente comparar las características sociodemográficas de la población de nacionalidad extranjera censada en Barcelona y la censada en el resto de Cataluña en 2001, teniendo en cuenta como principales variables la estructura por sexo, edad y nacionalidad, el nivel de instrucción y la relación con la a…
