Investigation of snow melt dynamics and boundary layer processes over a melting snow surface

In this thesis, we investigate the surface energy balance of a snow pack for a continuous and a patchy snow cover. Snow surface temperatures have been validated to assess the accuracy of the surface energy balance of a continuous snow pack for individual p ...

Improving surface heat flux estimation for a large lake through model optimization and two-point calibration: The case of Lake Geneva

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Andrea Cimatoribus, Abolfazl Irani Rahaghi

Net Surface Heat Flux (SurHF) was estimated from 2008 to 2014 for Lake Geneva (Switzerland/France), using long‐term temperature depth profiles at two locations, hourly maps of reanalysis meteorological data from a numerical weather model and lake surface w ...

Spatial variability of multi-annual seasonal surface heat flux patterns of Lake Geneva

David Andrew Barry, Ulrich Lemmin, Andrea Cimatoribus, Abolfazl Irani Rahaghi

The dynamics of the spatiotemporal surface heat flux (SurHF) of Lake Geneva (Switzerland/France) was estimated for a 7-y period. Data sources included hourly maps of over-the-lake assimilated meteorological data from a numerical weather model and Lake Surf ...

From COP21 pledges to a fair 2°C pathway

Marc Vielle, Frédéric Louis François Babonneau, Alain Haurie

At COP21, about 160 countries proposed the so-called INDCs that define GHG abatement objectives by 2030. While encouraging, these commitments are not ambitious enough to achieve the 2°C threshold by 2100, and further negotiations are needed for sharing the ...

Representation of Horizontal Transport Processes in Snowmelt Modeling by Applying a Footprint Approach

Michael Lehning, Sebastian Schlögl, Charles Fierz

The energy balance of an alpine snow cover significantly changes once the snow cover gets patchy. The local advection of warm air causes above-average snow ablation rates at the upwind edge of the snow patch. As lateral transport processes are typically no ...

Is the Thorpe and Mason model valid for drifting and blowing snow?

Varun Sharma, Michael Lehning, Francesco Comola

Sublimation of drifting and blowing snow has been recognized as an important component of the surface mass budget of polar and alpine regions. The Thorpe and Mason (TM) model is the basis of all existing small and largescale estimates of drifting snow sub ...

A new method to retrieve the real part of the equivalent refractive index of atmospheric aerosols

Athanasios Nenes

In the context of the international experimental campaign Hygroscopic Aerosols to Cloud Droplets (HygrA-CD, 15 May to 22 June 2014), dry aerosol size distributions were measured at Demokritos station (DEM) using a Scanning Mobility Particle Sizer (SMPS) in ...

Large wind farms can destroy stratocumulus clouds-evidence from large eddy simulations.

Varun Sharma, Michael Lehning, Marc Parlange, Marc Calaf Bracons

Stratocumulus is one of the most common cloud types found in the atmospheric boundary layer (ABL) and have been shown to have a significant impact on modulating the global radiation and energy balance. In spite of their ubiquitousness however, their shallo ...

Simulated heat storage in Canada's most northern lake: Towards a 3 dimensional model

Nicolas Bochaton

This work focuses on heat fluxes and hydrodynamic of Ward Hunt Lake, Canada's most northern lake, as well as its response to climate variations. The project aims to implement a heat budget model, in order to improve our understanding of underlying mechanis ...

Measurement of the impact of buildings on meteorological variables

Jean-Louis Scartezzini, Dasaraden Mauree, Laurent Deschamps, Pierre Loesch, Paul Becquelin

A meteorological tower was installed on the EPFL campus in a semi-urban environment for the high frequency monitoring of the micro-climate. This project was done in the larger framework of the measurement of the meteorological profiles and also a quantific ...
