Improving the degree-day method for sub-daily melt simulations with physically-based diurnal variations

Bettina Schaefli, Guillermo Barrenetxea Kobas, Marc Parlange, Cara Christine Tobin, Andrea Rinaldo, Silvia Simoni, Ludovico Nicotina

This paper proposes a new extension of the classical degree-day snowmelt model applicable to hourly simulations for regions with limited data and adaptable to a broad range of spatially-explicit hydrological models. The snowmelt schemes have been tested wi ...

Are atmospheric surface layer f lows ergodic?

Valentin Simeonov, Martin Froidevaux, Marc Parlange, Chad Higgins, Gabriel George Katul

The transposition of atmospheric turbulence statistics from the time domain, as conventionally sampled in field experiments, is explained by the so-called ergodic hypothesis. In micrometeorology, this hypothesis assumes that the time average of a measured ...

Flow during the evening transition over steep Alpine slopes

Marc Parlange, Wolf Hendrik Huwald, Chad Higgins, Daniel Nadeau, Eric Richard Pardyjak

A field campaign, the Slope Experiment near La Fouly (SELF-2010), was conducted to monitor the evening transition of slope flows on clear-sky days from July to September 2010 in a narrow valley of the Swiss Alps. A steep west-facing slope with inclinations ...

Could electrical conductivity replace water level in rating curves for alpine streams?

Marc Parlange, Raphaël Mutzner, Steven Vincent Weijs

Streamflow time series are important for inference and understanding of the hydrological processes in alpine watersheds. Because streamflow is expensive to continuously measure directly, it is usually derived from measured water levels, using a rating curv ...

Measured and Estimated Water Vapor Advection in the Atmospheric Surface Layer

Valentin Simeonov, Martin Froidevaux, Marc Parlange, Chad Higgins, Eric Richard Pardyjak

The flux of water vapor due to advection is measured using high-resolution Raman lidar that was orientated horizontally across a land-lake transition. At the same time, a full surface energy balance is performed to assess the impact of scalar advection on ...

Data compression to define information content of hydrological time series

Marc Parlange, Nicolaas Cornelis van de Giesen, Steven Vincent Weijs

When inferring models from hydrological data or calibrating hydrological models, we are interested in the information content of those data to quantify how much can potentially be learned from them. In this work we take a perspective from (algorithmic) inf ...

Evaporation from a shallow water table: Diurnal dynamics of water and heat at the surface of drying sand

Marc Parlange, Scott W. Tyler, Ivan Lunati, Chad Higgins

Accurate estimates of water losses by evaporation from shallow water tables are important for hydrological, agricultural, and climatic purposes. An experiment was conducted in a weighing lysimeter to characterize the diurnal dynamics of evaporation under n ...

Infiltration in soils with a saturated surface

Marc Parlange, David Andrew Barry

An earlier infiltration equation relied on curve fitting of infiltration data for the determination of one of the parameters, which limits its usefulness in practice. This handicap is removed here, and the parameter is now evaluated by linking it directly ...

Summer methane fluxes from a boreal bog in northern Quebec, Canada, using eddy covariance measurements

Marc Parlange, Daniel Nadeau

A boreal bog located in the James Bay lowlands, Canada, was instrumented with an open-path gas analyzer to monitor the turbulent fluxes of methane throughout the summer of 2012. The mostly continuous eddy covariance measurements permitted the study of meth ...

Coherent structures and the k(-1) spectral behaviour

Valentin Simeonov, Marc Parlange, Marc Calaf Bracons, Holly Jayne Oldroyd

l Here we present unique evidence of a k(-1) scaling behaviour in the atmospheric boundary layer and its connection to large scale coherent structures within the boundary layer. Wind lidar measurements were conducted above a lake under cold atmospheric con ...

Raman Lidar for Meteorological Observations, RALMO - Part 1: Instrument description

Bertrand Calpini, Hubert van den Bergh, Valentin Simeonov, Pablo Roberto Ristori, Todor Dinoev, Marc Parlange

A new Raman lidar for unattended, round-the-clock measurement of vertical water vapor profiles for operational use by the MeteoSwiss has been developed during the past years by the Swiss Federal Institute of Technology, Lausanne. The lidar uses narrow fiel ...

Thermal diffusivity of seasonal snow determined from temperature profiles

Marc Parlange, Wolf Hendrik Huwald, Chad Higgins, Holly Jayne Oldroyd

Thermal diffusivity of snow is an important thermodynamic property associated with key hydrological phenomena such as snow melt and heat and water vapor exchange with the atmosphere. Direct determination of snow thermal diffusivity requires coupled point m ...

A New Wall Shear Stress Model for Atmospheric Boundary Layer Simulations

Marc Parlange, Marc Calaf Bracons

A new wall shear stress model to be used as a wall boundary condition for large-eddy simulations of the atmospheric boundary layer is proposed. The new model computes the wall shear stress and the vertical derivatives of the streamwise velocity component b ...

Similarity Scaling Over a Steep Alpine Slope

Marc Parlange, Chad Higgins, Daniel Nadeau, Eric Richard Pardyjak

In this study,we investigate the validity of similarity scaling over a steep mountain slope (30–41◦). The results are based on eddy-covariance data collected during the Slope Experiment near La Fouly (SELF-2010); a field campaign conducted in a narrow vall ...

A Raman lidar to measure water vapor in the atmospheric boundary layer

Hubert van den Bergh, Valentin Simeonov, Martin Froidevaux, Pablo Roberto Ristori, Marc Parlange, Ilya Serikov, Chad Higgins, Eric Richard Pardyjak

A new multi-telescope scanning Raman lidar designed to measure the water vapor mixing ratio in the atmospheric boundary layer for a complete diurnal cycle with high resolution spatial (1.25 m) and temporal (1 s) resolutions is presented. The high resolutio ...

Geomorphic signatures on brutsaert base flow recession analysis

Marc Parlange, Raphaël Mutzner, Andrea Rinaldo, Enrico Bertuzzo, Nevena Tomasic, Serena Ceola, Ludovico Nicotina, Steven Vincent Weijs

This paper addresses the signatures of catchment geomorphology on base flow recession curves. Its relevance relates to the implied predictability of base flow features, which are central to catchment-scale transport processes and to ecohydrological functio ...

Flow over Hills: A Large-Eddy Simulation of the Bolund Case

Jiannong Fang, Marc Diebold, Marc Parlange, Chad Higgins

Simulation of local atmospheric flows around complex topography is important for several applications in wind energy (short-term wind forecasting and turbine siting and control), local weather prediction in mountainous regions and avalanche risk assessment ...

HydroZIP: How Hydrological Knowledge can Be Used to Improve Compression of Hydrological Data

Marc Parlange, Nicolaas Cornelis van de Giesen, Steven Vincent Weijs

From algorithmic information theory, which connects the information content of a data set to the shortest computer program that can produce it, it is known that there are strong analogies between compression, knowledge, inference and prediction. The more w ...

On the use of spatially discrete data to compute energy and mass balance

Marc Parlange, Ivan Lunati, Francesco Ciocca

In many practical applications the state of field soils is monitored by recording the evolution of temperature and soil moisture at discrete depths. We theoretically investigate the systematic errors that arise when mass and energy balances are computed di ...

Carbon monoxide as a tracer of gas transport in snow and other natural porous media

Marc Parlange, Marc Calaf Bracons, Wolf Hendrik Huwald, Scott W. Tyler, Nicolaas Cornelis van de Giesen

The movement of air in natural porous media is complex and challenging to measure. Yet gas transport has important implications, for instance, for the evolution of the seasonal snow cover and for water vapor transport in soil. A novel in situ multi-sensor ...
