Characterization of submicron aerosols during a month of serious pollution in Beijing, 2013 Atmospheric Chemistry and Physics DOI 10.5194/acp-14-2887-2014 20 March 2014 In January 2013, Beijing experienced several serious haze events. To achieve a better understanding of the characteristics, sources and processes of aerosols during this month, an Aerodyne high-resolution time-of-flight aerosol mass spectrometer was deployed at an urban site between 1 January and 1 February 2013 to obtain the size-resolved chemical composition of non-refractory submicron particles.

Observed decline of the Atlantic meridional overturning circulation 2004–2012 Ocean Science DOI 10.5194/os-10-29-2014 6 February 2014 The Atlantic meridional overturning circulation and its component parts are monitored by combining a transatlantic array of moored instruments with submarine-cable-based measurements of the Gulf Stream and satellite derived Ekman transport. The time series has recently been extended to October 2012 and the results show a downward trend since 2004. Read more
Using palaeo-climate comparisons to constrain future projections in CMIP5 Climate of the Past DOI 10.5194/cp-10-221-2014 5 February 2014 We present a selection of methodologies for using the palaeo-climate model component of the Coupled Model Intercomparison Project (Phase 5) to attempt to constrain future climate projections using the same models.

Autonomous thermal camera system for monitoring the active lava lake at Erebus volcano, Antarctica Geoscientific Instrumentation, Methods and Data Systems DOI 10.5194/gi-3-13-2014 5 February 2014 In December 2012, the Mount Erebus Volcano Observatory installed a thermal infrared camera system to monitor the volcano’s active lava lake. The new system is designed to be autonomous, and capable of capturing images of the lava lake continuously throughout the year. Read more
