Comparison between open-site and below-canopy climatic conditions in Switzerland for different types of forests over 10 years (1998-2007)

We compared below-canopy and open-site climatic conditions for 14 different forest sites in Switzerland and analysed the forest influence on local summer and winter climate according to the forest type (coniferous, mixed, deciduous), soil type, slope orien ...

Extreme temperature analysis under forest cover compared to an open field

Anthony Christopher Davison, Martine Rebetez, Jacques Ferrez

We analyse air temperature data from 14 sites in Switzerland, each with two weather stations in close proximity, one under a forest canopy and the other in the open. We use the statistics of extremes to investigate how extremely high maximum and extremely ...

Comparaison des caractéristiques climatiques sous couvert forestier et hors couvert

Valentine Renaud

We compared open-site and below-canopy climatic conditions from 14 different sites in Switzerland based on LWF data (Long-term Forest Ecosystem Research). The 14 sites represent different locations, orientations and elevations, from the Jura Mountains to t ...

Wind sheltering of a lake by a tree canopy or bluff topography

Fernando Porté Agel, Corey Dean Markfort

[1] A model is developed to quantify the wind sheltering of a lake by a tree canopy or a bluff. The experiment-based model predicts the wind-sheltering coefficient a priori, without calibration, and is useful for one-dimensional (1-D) lake hydrodynamic and ...

Field experiments using CO2 enrichment: a comparison of two main methods

The dramatic increase in global atmospheric carbon dioxide over the past century is hypothesized to have significant impacts on the earth system. To understand the effects of elevated CO2 on terrestrial ecosystems, two main methods have been used to simula ...

Gravel bar inundation frequency : an indicator fort he ecological potentiel of a river

Anton Schleiss, Walter Gostner

In braiding river systems, gravel bars fulfill important ecological functions. At the River Sense, one of the last unregulated rivers in Switzerland, the frequency of gravel bar inundation of a 2 km long site maintaining indicator species such as Myricaria ...

Comparison between open-site and below-canopy climatic conditions in Switzerland during the exceptionally hot summer of 2003

Martine Rebetez, Valentine Renaud

We compared open-site and below-canopy climatic conditions from 14 different sites in Switzerland based on LWF (Long-term Forest Ecosystem Research) data. The 14 sites represent different locations, orientations and elevations, from the Jura Mountains to t ...

Topographic, meteorologic, and canopy controls on the scaling characteristics of the spatial distribution of snow depth fields

Ernesto Trujillo Gomez

In this study, LIDAR snow depths, bare ground elevations (topography), and elevations filtered to the top of vegetation (topography + vegetation) in five 1-km2 areas are used to determine whether the spatial distribution of snow depth exhibits scale invari ...

Short-term effects of cattle browsing on tree sapling growth in mountain wooded pastures

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

Browsing by livestock has been identified as an important factor preventing tree regeneration in wooded pastures. Two field experiments were performed to investigate the effects of cattle browsing on tree sapling growth in a mountainwooded pasture. Two siz ...

Frequency- and Time-Domain Measurement of Bare Soils and Wheat Canopy Using Monostatic Horn Antenna GPR - Implications and Applications for Radar Remote Sensing

Dani Or

GPR with a suspended 1 GHz horn antenna was deployed in the greenhouse and field for measurement of near-surface hydrologic parameters over bare and wheat canopy covered soils. Analyses of time-domain (TD) surface reflections (SR) and signal propagation ti ...
