Mapping the physico-chemical properties of mineral dust in western Africa: mineralogical composition Atmospheric Chemistry and Physics DOI 10.5194/acp-14-10663-2014 10 October 2014 In the last few years, several ground-based and airborne field campaigns have allowed the exploration of the properties and impacts of mineral dust in western Africa. This paper explores the synthesis of these observations to provide a large-scale quantitative view of the mineralogical composition and its variability according to source region and time after transport.

The origin of noise and magnetic hysteresis in crystalline permalloy ring-core fluxgate sensors Geoscientific Instrumentation, Methods and Data Systems DOI 10.5194/gi-3-201-2014 29 September 2014 In certain polycrystalline permalloy fluxgate sensors, a single phenomenon may cause both fluxgate noise and magnetic hysteresis; explain Barkhausen jumps, remanence and coercivity; and avoid domain denucleation. This phenomenon, domain wall reconnection, is presented as part of a theoretical model. Read more
The effect of changing sea ice on the physical vulnerability of Arctic coasts The Cryosphere DOI 10.5194/tc-8-1777-2014 26 September 2014 Sea ice provides a first-order control on the physical vulnerability of Arctic coasts to erosion, inundation, and damage to settlements and infrastructures by ocean water. This paper focuses on how the changing sea-ice cover has influenced coastal erosion over the satellite record. Read more
A framework for benchmarking of homogenisation algorithm performance on the global scale Geoscientific Instrumentation, Methods and Data Systems DOI 10.5194/gi-3-187-2014 25 September 2014 The International Surface Temperature Initiative (ISTI) is striving towards substantively improving our ability to robustly understand historical land surface air temperature change at all scales. A key recently completed first step has been collating all available records into a comprehensive open access, traceable and version-controlled databank. Read more
The XWS open access catalogue of extreme European windstorms from 1979 to 2012 Natural Hazards and Earth System Sciences DOI 10.5194/nhess-14-2487-2014 22 September 2014 This papers introduces the XWS (eXtreme WindStorms) catalogue, which consists of storm tracks and model-generated maximum 3 s wind-gust footprints for 50 of the most extreme winter windstorms to hit Europe in the period 1979–2012. XWS open access catalogue of extreme European windstorms from 1979 to 2012">Read more
The length of the world’s glaciers – a new approach for the global calculation of center lines The Cryosphere DOI 10.5194/tc-8-1741-2014 19 September 2014 Here the authors present a first global assessment of glacier length using an automated method that relies on glacier surface slope, distance to the glacier margins and a set of trade-off functions.

Smoothing error pitfalls Atmospheric Measurement Techniques DOI 10.5194/amt-7-3023-2014 18 September 2014 The difference due to the content of a priori information between a constrained retrieval and the true atmospheric state is usually represented by a diagnostic quantity called smoothing error. In this paper it is shown that the concept of the smoothing error as a component of the retrieval error budget is questionable because it is not compliant with Gaussian error propagation. Read more
