Incorporation of advanced aerosol activation treatments into CESM/CAM5: Model evaluation and impacts on aerosol indirect effects

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

One of the greatest sources of uncertainty in the science of anthropogenic climate change is from aerosol-cloud interactions. The activation of aerosols into cloud droplets is a direct microphysical linkage between aerosols and clouds; parameterizations of ...

Modelling Small-Scale Drifting Snow with a Lagrangian Stochastic Model Based on Large-Eddy Simulations

Michael Lehning, Marc Parlange, Marc Diebold, Jan Overney, Gian-Duri Lieberherr

Observations of drifting snow on small scales have shown that, in spite of nearly steady winds, the snow mass flux can strongly fluctuate in time and space. Most drifting snow models, however, are not able to describe drifting snow accurately over short ti ...

Understanding the contributions of aerosol properties and parameterization discrepancies to droplet number variability in a global climate model

Athanasios Nenes

Aerosol indirect effects in climate models strongly depend on the representation of the aerosol activation process. In this study, we assess the process-level differences across activation parameterizations that contribute to droplet number uncertainty by ...

Solving Richards Equation for snow improves snowpack meltwater runoff estimations in detailed multi-layer snowpack model

Michael Lehning, Nander Wever, Charles Fierz

The runoff from a snow cover during spring snowmelt or rain-on-snow events is an important factor in the hydrological cycle. In this study, three water balance schemes for the 1 dimensional physically-based snowpack model SNOWPACK are compared to lysimeter ...

Modeling the monthly mean stream temperature dynamics

Michael Lehning, Wolf Hendrik Huwald, Bettina Schaefli, Aurélien Gallice

Water temperature is a hydrological factor which affects the habitat suitability of many aquatic (fish) species, and is therefore of great concern in the actual context of climate change. Two types of models are currently used to simulate stream temperatur ...

Observation of Sensible and Latent Heat Fluxes Over a Mixed Savanna – Agricultural Catchment in the Semi-Arid Sudanian Savanna, Burkina Faso

Andrea Rinaldo, Marc Parlange, Natalie Claire Ceperley, Theophile Mande, Nicolaas Cornelis van de Giesen, Scott W. Tyler

Evaporation and the surface energy balance over two land cover types in Sudanian savanna were investigated in terms of their seasonal and interannual variability using four years of eddy covariance measurement (2009-2013). The observations demonstrate the ...

Urban Form Optimization for the Energy Performance of Buildings Using Citysim

Jérôme Henri Kämpf

The energy efficiency of the urban texture relies notably on the buildings’ form, which characterizes its capability to take profit of the solar potential as well as its loss of energy through the envelope. Therefore, the general layout at the district sca ...

EPFL Solar Energy and Building Physics Laboratory (LESO-PB)2013

The Uncertainty of Seasonal Snow Energy- and Mass Balance Simulations as a Function of Typical Input Uncertainty

Michael Lehning, Mathias Thierry Pierre Bavay, Charles Fierz

The assessment of water resources and their change in time as well as many other applications from hydrology to meteorology require the successful modelling of the dynamics of the seasonal snow cover. Especially if extrapolation in time, e.g. for climate c ...

Beyond Point Measurements: Sea Ice Floes Characterized in 3-D

Katherine Colby Leonard, Ernesto Trujillo Gomez

A new methodology for coincident floe-scale measurements of the surface elevation, snow depth, and ice draft (the thickness below the water line) of Antarctic sea ice has been demonstrated during two recent research voyages: the Australian-led Sea Ice Phys ...
