Value of medium range weather forecasts in the improvement of seasonal hydrologic prediction skill Hydrology and Earth System Sciences DOI 10.5194/hess-16-2825-2012 17 August 2012 We investigated the contribution of medium range weather forecasts with lead times of up to 14 days to seasonal hydrologic prediction skill over the conterminous United States (CONUS).

Photoproduction of ammonium in the southeastern Beaufort Sea and its biogeochemical implications Biogeosciences DOI 10.5194/bg-9-3047-2012 10 August 2012 During the August 2009 Mackenzie Light and Carbon (MALINA) Program, the absorbed photon-based efficiency spectra of NH4+photoproduction (i.e. photoammonification) were determined using water samples from the SE Beaufort Sea, including the Mackenzie River estuary, shelf, and Canada Basin.

Assessing climate model software quality: a defect density analysis of three models Geoscientific Model Development DOI 10.5194/gmd-5-1009-2012 9 August 2012 We found that the climate models all have very low defect densities compared to well-known, similarly sized open-source projects. We discuss the implications of our findings for the assessment of climate model software trustworthiness. Read more
Effects of business-as-usual anthropogenic emissions on air quality Atmospheric Chemistry and Physics DOI 10.5194/acp-12-6915-2012 1 August 2012 The atmospheric chemistry general circulation model EMAC has been used to estimate the impact of anthropogenic emission changes on global and regional air quality in recent and future years (2005, 2010, 2025 and 2050). The emission scenario assumes that population and economic growth largely determine energy and food consumption and consequent pollution sources with the current technologies (“business as usual”).

Aerosol information content analysis of multi-angle high spectral resolution measurements and its benefit for high accuracy greenhouse gas retrievals Atmospheric Measurement Techniques DOI 10.5194/amt-5-1809-2012 27 July 2012 In this paper, we investigate the combined aerosol and greenhouse gas retrieval using multiple satellite viewing angles simultaneously. We find that this method greatly enhances the ability to retrieve aerosol properties by 2–3 degrees of freedom. Read more
Statistical adaptation of ALADIN RCM outputs over the French Alps – application to future climate and snow cover The Cryosphere DOI 10.5194/tc-6-785-2012 24 July 2012 In this study, snowpack scenarios are modelled across the French Alps using dynamically downscaled variables from the ALADIN Regional Climate Model (RCM) for the control period (1961–1990) and three emission scenarios (SRES B1, A1B and A2) for the mid- and late 21st century (2021–2050 and 2071–2100).

Climatic and geologic controls on suspended sediment flux in the Sutlej River Valley, western Himalaya Hydrology and Earth System Sciences DOI 10.5194/hess-16-2193-2012 20 July 2012 Here, we present a comprehensive analysis of the spatiotemporal trends in suspended sediment flux based on daily data during the past decade (2001–2009) from four sites along the Sutlej River and from four of its main tributaries.

Enhancing flood resilience through improved risk communications Natural Hazards and Earth System Sciences DOI 10.5194/nhess-12-2271-2012 20 July 2012 A framework of guiding recommendations for effective pre-flood and flood warning communications derived from the URFlood project (2nd ERA-Net CRUE Research Funding Initiative) from extensive quantitative and qualitative research in Finland, Ireland, Italy and Scotland is presented.

Risk perception – issues for flood management in Europe Natural Hazards and Earth System Sciences DOI 10.5194/nhess-12-2299-2012 20 July 2012 Public perception of flood risk and flood risk information is often overlooked when developing flood risk management plans. As scientists and the public at large perceive risk in very different ways, flood risk management strategies are known to have failed in the past due to this disconnect between authorities and the public. This paper uses a novel approach in exploring the role of public perception in developing flood risk communication strategies in Europe. Read more
Detecting anthropogenic carbon dioxide uptake and ocean acidification in the North Atlantic Ocean Biogeosciences DOI 10.5194/bg-9-2509-2012 11 July 2012 Fossil fuel use, cement manufacture and land-use changes are the primary sources of anthropogenic carbon dioxide (CO2) to the atmosphere, with the ocean absorbing approximately 30% (Sabine et al., 2004). Ocean uptake and chemical equilibration of anthropogenic CO2 with seawater results in a gradual reduction in seawater pH and saturation states (Ω) for calcium carbonate (CaCO3) minerals in a process termed ocean acidification.
