Light-absorbing impurities enhance glacier albedo reduction in the southeastern Tibetan plateau

Light‐absorbing impurities (LAIs) in snow of the southeastern Tibetan Plateau (TP) and their climatic impacts are of interest not only because this region borders areas affected by the South Asian atmospheric brown clouds but also because the seasonal snow ...

Top-of-atmosphere radiative forcing affected by brown carbon in the upper troposphere

Yi Zhang, Athanasios Nenes, Junqiu Liu, Yi Wang

Carbonaceous aerosols affect the global radiative balance by absorbing and scattering radiation, which leads to warming or cooling of the atmosphere, respectively. Black carbon is the main light-absorbing component. A portion of the organic aerosol known a ...

Asymmetric effects of cooler and warmer winters on beech phenology last beyond spring

Alexandre Buttler, Rodolphe Schlaepfer, Yann Vitasse, Constant Signarbieux, María Paula Sanginés De Cárcer, Ester Toledano Díaz

In temperate trees, the timings of plant growth onset and cessation affect biogeochemical cycles, water, and energy balance. Currently, phenological studies largely focus on specific phenophases and on their responses to warming. How differently spring phe ...

Negative elevation-dependent warming trend in the Eastern Alps

Mountain regions and the important ecosystem services they provide are considered to be very vulnerable to the current warming, and recent studies suggest that high-mountain environments experience more rapid changes in temperature than environments at low ...

Experimental and Numerical Characterization of a New 45 kWel Multisource High-Flux Solar Simulator

Sophia Haussener, Gaël Jean Clément Levêque

The performance of a new high-flux solar simulator consisting of 18 × 2.5 kWel radiation modules has been evaluated. Grayscale images of the radiative flux distribution at the focus are acquired for each module individually using a water-cooled Lambertian ...

Spatial estimates of snow water equivalent from reconstruction

Annelen Kahl

Operational ground-based measurements of snow water equivalent (SWE) do not adequately explain spatial variability in mountainous terrain. To address this problem, we combine satellite-based retrievals of fractional snow cover for the period 2000 to 2011 w ...

Assessing wet snow avalanche activity using detailed physics based snowpack simulations

Nander Wever, Charles Fierz

Water accumulating on microstructural transitions inside a snowpack is often considered a prerequisite for wet snow avalanches. Recent advances in numerical snowpack modeling allow for an explicit simulation of this process. We analyze detailed snowpack si ...

Numerical study of potential heat flux mitigation effects in the TCV snowflake divertor

Basil Duval, Holger Reimerdes, Benoît Labit, Marco Wischmeier, Wouter Vijvers

We report on EMC3-Eirene simulations of the plasma and neutral particle transport the TCV boundary layer of a series of snowflake (SF) equilibria characterized by the normalized poloidal flux coordinate rho(x2) of the secondary X-point x(2). We refer to a ...

Operational snowcover simulations with avalanche dynamics calculations coupling to assess avalanche danger in high altitude mining operations

Nander Wever

The Codelco Andina copper mine is operating in high alpine terrain where avalanches pose a threat to the operations and the infrastructure. A dedicated avalanche warning service is responsible for opening and closing the heavily used access road. To suppor ...

Incorporating an advanced aerosol activation parameterization into WRF-CAM5: Model evaluation and parameterization intercomparison

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

Aerosol activation into cloud droplets is an important process that governs aerosol indirect effects. The advanced treatment of aerosol activation by Fountoukis and Nenes (2005) and its recent updates, collectively called the FN series, have been incorpora ...
