Oxidation of SO2 by stabilized Criegee intermediate (sCI) radicals as a crucial source for atmospheric sulfuric acid concentrations Atmospheric Chemistry and Physics DOI 10.5194/acp-13-3865-2013 12 April 2013 The effect of increased reaction rates of stabilized Criegee intermediates (sCIs) with SO2 to produce sulfuric acid is investigated using data from two different locations, SMEAR II, Hyytiälä, Finland, and Hohenpeissenberg, Germany.

Inverse estimation of source parameters of oceanic radioactivity dispersion models associated with the Fukushima accident Biogeosciences DOI 10.5194/bg-10-2349-2013 9 April 2013 With combined use of the ocean–atmosphere simulation models and field observation data, we evaluate the parameters associated with the total caesium-137 amounts of the direct release into the ocean and atmospheric deposition over the western North Pacific caused by the accident of Fukushima Daiichi nuclear power plant that occurred in March 2011.

Scenario and modelling uncertainty in global mean temperature change derived from emission-driven global climate models Earth System Dynamics DOI 10.5194/esd-4-95-2013 8 April 2013 We compare future changes in global mean temperature in response to different future scenarios which, for the first time, arise from emission-driven rather than concentration-driven perturbed parameter ensemble of a global climate model.

Short- and long-term consequences of larval stage exposure to constantly and ephemerally elevated carbon dioxide for marine bivalve populations Biogeosciences DOI 10.5194/bg-10-2241-2013 5 April 2013 Experiments were performed to assess the short-term (days) and long-term (months) consequences of larval stage exposure to varying CO2 concentrations for calcifying bivalves. The findings suggested that high CO2 has a cascading negative physiological impact on bivalve larvae stemming in part from lower calcification rates. Read more
Ice-shelf buttressing and the stability of marine ice sheets The Cryosphere DOI 10.5194/tc-7-647-2013 4 April 2013 Ice-shelf buttressing and the stability of marine-type ice sheets are investigated numerically. Buttressing effects are analysed for a situation where a stable grounding line is located on a bed sloping upwards in the direction of flow. Read more
Interpreting muon radiographic data in a fault zone: possible application to geothermal reservoir detection and monitoring Geoscientific Instrumentation, Methods and Data Systems DOI 10.5194/gi-2-145-2013 27 March 2013 In this report, the data taken by Tanaka et al. (2011) are reanalyzed to estimate the porosity distribution as a function of a distance from the fault gouge. The result shows a similar pattern of the porosity distribution as measured by borehole sampling at Nojima fault. Read more
The influence of climate change on flood risks in France – first estimates and uncertainty analysis Natural Hazards and Earth System Sciences DOI 10.5194/nhess-13-809-2013 27 March 2013 This paper proposes a methodology to project the possible evolution of river flood damages due to climate change, and applies it to mainland France.

Mechanisms causing reduced Arctic sea ice loss in a coupled climate model The Cryosphere DOI 10.5194/tc-7-555-2013 26 March 2013 The fully coupled climate model HadGEM1 produces one of the most accurate simulations of the historical record of Arctic sea ice seen in the IPCC AR4 multi-model ensemble. In this study, we examine projections of sea ice decline out to 2030, produced by two ensembles of HadGEM1 with natural and anthropogenic forcings included. Read more
Meteorological observations on the northern Chilean coast during VOCALS-REx Atmospheric Chemistry and Physics DOI 10.5194/acp-13-3409-2013 25 March 2013 Surface coastal observations from two automatic weather stations at Paposo (~25° S) and radiosonde observations at Paposo and Iquique (~20° S) were carried out during VOCALS-REx (VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment).

Host model uncertainties in aerosol radiative forcing estimates: results from the AeroCom Prescribed intercomparison study Atmospheric Chemistry and Physics DOI 10.5194/acp-13-3245-2013 20 March 2013 In this AeroCom Prescribed intercomparison study we systematically isolate and quantify host model uncertainties on aerosol forcing experiments through prescription of identical aerosol radiative properties in twelve participating models.
