Antonio Herráiz, mueblista de la vivienda de Julio Muñoz Ramonet en Barcelona.
No full textAntonio Herráiz was the author of the pieces of furniture from two of Julio Muñoz Ramonet Barcelona’s houses, which were decorated in 1945. We document the authorship and analyze the aesthetic keys of these high bourgeoisie houses, which have come down to us intact. The paper allow us to study the work this important furniture and art bronzes company from Madrid with branch in Barcelona, specialized in recreate European classic styles.Antonio Herráiz fue el autor de los muebles de los dos edificios que Julio Muñoz Ramonet compró en Barcelona en 1945. Documentamos la autoría y analizamos las claves estéticas de unos destacados interiores de la alta burguesía barcelonesa que han llegado intactos hasta nosotros. El trabajo nos ha permitido referenciar la obra de esta importante empresa de muebles y bronces artísticos de Madrid con sucursal en Barcelona, que versionaba los estilos clásicos europeos

Ramonet (2010) Is the recent build-up of atmospheric CO 2 over Europe reproduced by models. Part 2: an overview with the atmospheric mesoscale transport model CHIMERE, A B S T R A C T In this issue, Ramonet et al. revealed a positive trend in European, atmospheric CO 2 concentrations relative to a marine, North Atlantic reference baseline, for the years 2001-2006. The observed build up mainly occurred during the cold season where it reaches a 0.8 ppm yr −1 at low-altitude stations to a 0.3 ppm yr −1 at mid-altitude stations. We explore the cause of this build-up using the mesoscale model CHIMERE. We first model the observed trends, using interannually varying fluxes and transport, then suppress the interannual variability in fluxes or aspects of transport to elucidate the cause. The run with no interannual variability in fluxes still matches observed trends suggesting that transport is the major cause. Separate runs varying either boundary layer height or winds show that changes in boundary layer height explain the trends at low-altitude stations within the continents while changes in wind regimes drive changes elsewhere

No full textHigh time resolution aerosol mass spectrometry measurements were conducted during a field campaign at Mace Head Research Station, Ireland, in June 2007. Observations on one particular day of the campaign clearly indicated advection of aerosol from volcanoes and desert plains in Iceland which could be traced with NOAA Hysplit air mass back trajectories and satellite images. In conjunction with this event, elevated levels of sulphate and light absorbing particles were encountered at Mace Head. While sulphate concentration was continuously increasing, nitrate levels remained low indicating no significant contribution from anthropogenic pollutants. Sulphate concentration increased about 3.8 g/m3 in comparison with the background conditions. Corresponding sulphur flux from volcanic emissions was estimated to about 0.3 TgS/yr, suggesting that a large amount of sulphur released from Icelandic volcanoes may be distributed over distances larger than 1000 km. Overall, our results corroborate that transport of volcanogenic sulphate and dust particles can significantly change the chemical composition, size distribution, and optical properties of aerosol over the North Atlantic Ocean and should be considered accordingly by regional climate models

Radon-222 (222Rn) measurements were added in May 2009. Background seasonal cycles, based on afternoon values, exhibit an amplitude of 45 and 60 ppb for H2 and CO, respectively, for the three different heights (50, 100 and 180 m above ground). The vertical gradient also shows seasonal variations with a maximum (during the night) of 20 and 45 ppb for H2 and CO, respectively.We also observe diurnal cycles for H2 and CO for the three different heights. In the afternoon, the mixing ratios at the three different heights are similar and are comparable with maritime background stations, such as Mace Head (Ireland). The diurnal cycle of 222Rn follows the boundary layer height variations, with maximum values in the morning. Throughout the year but especially in summer and autumn, the H2 mixing ratio shows nighttime depletion, with the lowest values at 06:00 UTC, due to soil uptake and the low boundary layer height. Using a simple box approach and the Radon-Tracer-Method, the H2 deposition velocity is calculated for the catchment area of Trainou.We find a mean value for the H2 deposition velocity of 2.6 ± 0.9 10-2 cm-2 s-1. During wintertime, H2 and CO are sometimes strongly correlated leading to a H2/CO ratio around 0.25. This ratio is lower than the ratio from traffic emissions, thus highlighting the mixing of sources in this area
