Estimating the Greenland ice sheet surface mass balance contribution to future sea level rise using the regional atmospheric climate model MAR The Cryosphere DOI 10.5194/tc-7-469-2013 14 March 2013 To estimate the sea level rise originating from changes in surface mass balance of the Greenland ice sheet, we present 21st century climate projections obtained with the regional climate model MAR (Modèle Atmosphérique Régional), forced by output of three CMIP5 (Coupled Model Intercomparison Project Phase 5) general circulation models.

The Geminid meteor shower during the ECOMA sounding rocket campaign: specular and head echo radar observations Annales Geophysicae DOI 10.5194/angeo-31-473-2013 12 March 2013 The ECOMA (Existence of Charge state Of meteoric smoke particles in the Middle Atmosphere) sounding rocket campaign was conducted during the Geminid meteor shower in December 2010 in order to explore whether there is a change of the properties of meteoric smoke particles due to the stream.

Quantifying the uncertainty in simulating global tropospheric composition due to the variability in global emission estimates of Biogenic Volatile Organic Compounds Atmospheric Chemistry and Physics DOI 10.5194/acp-13-2857-2013 11 March 2013 In this study we examine the contribution of biogenic volatile organic compounds towards global tropospheric composition using the global 3-D chemistry transport model TM5 and the recently developed modified CB05 chemical mechanism.

Application of soil quality indices to assess the status of agricultural soils irrigated with treated wastewaters Solid Earth DOI 10.5194/se-4-119-2013 7 March 2013 In this work two soil quality indices were used to evaluate the effects of irrigation with treated wastewater in soils. The indices were developed studying different soil properties in undisturbed soils in SE Spain, and the relationships between soil parameters were established using multiple linear regressions.

A statistical analysis of insurance damage claims related to rainfall extremes Hydrology and Earth System Sciences DOI 10.5194/hess-17-913-2013 4 March 2013 In this paper, a database of water-related insurance damage claims related to private properties and content was analysed. The aim was to investigate whether the probability of occurrence of rainfall-related damage was associated with the intensity of rainfall. Read more
Surface undulations of Antarctic ice streams tightly controlled by bedrock topography The Cryosphere DOI 10.5194/tc-7-407-2013 1 March 2013 In our work we use recently acquired airborne radar data for the Rutford Ice Stream and Evans Ice Stream, and we show that the surface response of fast-flowing ice is highly sensitive to bedrock irregularities with wavelengths of several ice thicknesses.

A unified approach to infrared aerosol remote sensing and type specification Atmospheric Chemistry and Physics DOI 10.5194/acp-13-2195-2013 25 February 2013 Here we use high resolution infrared measurements for aerosol type differentiation, exploiting, in that part of spectrum, the dependency of their refractive index on wavelength. We review existing detection methods and present a unified detection method based on linear discrimination analysis. Read more
An unknown oxidative metabolism substantially contributes to soil CO2 emissions Biogeosciences DOI 10.5194/bg-10-1155-2013 21 February 2013 The respiratory release of CO2 from soils is a major determinant of the global carbon cycle. It is traditionally considered that this respiration is an intracellular metabolism consisting of complex biochemical reactions carried out by numerous enzymes and co-factors. Here we show that the endoenzymes released from dead organisms are stabilised in soils and have access to suitable substrates and co-factors to permit function. Read more
Ion motion in the current sheet with sheared magnetic field – Part 1: Quasi-adiabatic theory Nonlinear Processes in Geophysics DOI 10.5194/npg-20-163-2013 21 February 2013 We present a theory of trapped ion motion in the magnetotail current sheet with a constant dawn–dusk component of the magnetic field. Particle trajectories are described analytically using the quasi-adiabatic invariant corresponding to averaging of fast oscillations around the tangential component of the magnetic field. Read more
Radiative forcing of the direct aerosol effect from AeroCom Phase II simulations Atmospheric Chemistry and Physics DOI 10.5194/acp-13-1853-2013 19 February 2013 We report on the AeroCom Phase II direct aerosol effect (DAE) experiment where 16 detailed global aerosol models have been used to simulate the changes in the aerosol distribution over the industrial era. All 16 models have estimated the radiative forcing of the anthropogenic DAE, and have taken into account anthropogenic sulphate, black carbon and organic aerosols from fossil fuel, biofuel, and biomass burning emissions.
