The parameterization of the atmospheric boundary layer is essential for accurate numerical weather predictions. The near-surface values of air temperature or wind speed for instance are highly dependent on the complex land – atmosphere interactions over he ...
This work outlines two approaches for small unmanned aerial vehicles (UAVs) performing surveillance with fixed cameras. Small UAVs present significant control challenges, due to relatively low-bandwidth actuation and significant disturbances due to wind. T ...
This paper presents a novel method to predict the outdoor ground surface temperature, which can be useful in the estimation of urban heat islands (UHI) eect. A model is developed based on a multi-layer ground surface energy balance calculated on an hourly ...
The relative pollen productivity (RPP) of Pinus cembra, Larix, Picea, Gramineae, and Cyperaceae was estimated for the Upper Engadine area, an inner-alpine sub-continental valley in SE Switzerland lying above 1800 m a.s.l. The influx of pollen originating f ...
When assessing the economic viability of a wind farm, the estimation of the on-site wind power potential is perhaps the most important step. The most common way of evaluating the wind power potential of an area of interest consists of making on-site measur ...
Accurate microscale windfields computations over complex topography is crucial to many particle transport models but remains a challenging task. The objective of this work focuses on the numerical simulations of micro-scale windfields over the steep Gauder ...
Since regulations concerning traffic noise are becoming more and more demanding, meteorological effects (turbulence, temperature and wind speed gradients) can no more be neglected in noise propagation prediction at long ranges. To validate numerical models ...
