Re-establishing glacier monitoring in Kyrgyzstan and Uzbekistan, Central Asia
(2017)Geoscientific Instrumentation, Methods and Data SystemsGlacier mass loss is among the clearest indicators of atmospheric warming. The observation of these changes is one of the major objectives of the international climate monitoring strategy developed by the Global Climate Observing System (GCOS). Long-term glacier mass balance measurements are furthermore the basis for calibrating and validating models simulating future runoff of glacierised catchments. This is essential for Central Asia, ...Journal Article -
A non-stationary stochastic ensemble generator for radar rainfall fields based on the short-space Fourier transform
(2017)Hydrology and Earth System SciencesIn this paper we present a non-stationary stochastic generator for radar rainfall fields based on the short-space Fourier transform (SSFT). The statistical properties of rainfall fields often exhibit significant spatial heterogeneity due to variability in the involved physical processes and influence of orographic forcing. The traditional approach to simulate stochastic rainfall fields based on the Fourier filtering of white noise is only ...Journal Article -
An upper-branch Brewer-Dobson circulation index for attribution of stratospheric variability and improved ozone and temperature trend analysis
(2016)Atmospheric Chemistry and PhysicsWe find that wintertime temperature anomalies near 4 hPa and 50 N/S are related, through dynamics, to anomalies in ozone and temperature, particularly in the tropical stratosphere but also throughout the upper stratosphere and mesosphere. These mid-latitude anomalies occur on timescales of up to a month, and are related to changes in wave forcing. A change in the meridional Brewer–Dobson circulation extends from the middle ...Journal Article -
PathfinderTURB: an automatic boundary layer algorithm. Development, validation and application to study the impact on in situ measurements at the Jungfraujoch
(2017)Atmospheric Chemistry and PhysicsWe present the development of the PathfinderTURB algorithm for the analysis of ceilometer backscatter data and the real-time detection of the vertical structure of the planetary boundary layer. Two aerosol layer heights are retrieved by PathfinderTURB: the convective boundary layer (CBL) and the continuous aerosol layer (CAL). PathfinderTURB combines the strengths of gradient- and variance-based methods and addresses the layer attribution ...Journal Article -
Measurements of differential cross sections for associated production of a W boson and jets in proton-proton collisions at √s = 8 TeV
(2017)Physical Review DDifferential cross sections for a W boson produced in association with jets are measured in a data sample of proton-proton collisions at a center-of-mass energy of 8 TeV recorded with the CMS detector and corresponding to an integrated luminosity of 19.6 fb−1. The W bosons are identified through their decay mode W→μν. The cross sections are reported as functions of jet multiplicity, transverse momenta, and the scalar sum of jet transverse ...Journal Article -
Test beam performance measurements for the Phase I upgrade of the CMS pixel detector
(2017)Journal of InstrumentationA new pixel detector for the CMS experiment was built in order to cope with the instantaneous luminosities anticipated for the Phase I Upgrade of the LHC . The new CMS pixel detector provides four-hit tracking with a reduced material budget as well as new cooling and powering schemes. A new front-end readout chip mitigates buffering and bandwidth limitations, and allows operation at low comparator thresholds. In this paper, comprehensive ...Journal Article -
A comparison of two chemistry and aerosol schemes on the regional scale and the resulting impact on radiative properties and liquid- and ice-phase aerosol-cloud interactions
(2017)Atmospheric Chemistry and PhysicsThe complexity of atmospheric aerosol causes large uncertainties in its parameterization in atmospheric models. In a process-based comparison of two aerosol and chemistry schemes within the regional atmospheric modeling framework COSMO-ART (Consortium for Small-Scale Modelling, Aersosol and Reactive Trace gases extension), we identify key sensitivities of aerosol parameterizations. We consider the aerosol module MADE (Modal Aerosol Dynamics ...Journal Article -

Community climate simulations to assess avoided impacts in 1.5 and 2°C futures
(2017)Earth System DynamicsThe Paris Agreement of December 2015 stated a goal to pursue efforts to keep global temperatures below 1.5 °C above preindustrial levels and well below 2 °C. The IPCC was charged with assessing climate impacts at these temperature levels, but fully coupled equilibrium climate simulations do not currently exist to inform such assessments. In this study, we produce a set of scenarios using a simple model designed to achieve long-term 1.5 ...Journal Article -
Research on Natural Resources: The Quest for Integration Revisited
(2017)GAIA - Ecological Perspectives for Science and SocietyThe dysfunctional use of resources in modern societies arises from increasingly fragmented ways of understanding natural resources. Consequently, there have been repeated calls for integrative knowledge production, and various approaches to integration have been proposed, including such as interdisciplinary or transdisciplinary resource research and integrated resource management. The conceptual space proposed here can be applied as a ...Journal Article
