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 ...
Measuring emissions from nonuniform area sources, such as waste repository sites, has been a difficult problem. A simple but reliable method is not available. An objective method of inverting downwind concentration measurements, utilizing an assumed form o ...
From a data set collected during the MEDCAPHOT-TRACE field campaign, we demonstrate that ozone fluxes can be detd. with a shot-per-shot DIAL instrument operated in the UV spectral region. This is done by the simultaneous reconstruction of ozone concns. and ...
A study of the long-term changes of various climatic extremes was made jointly by a number of European countries. It was found that the changes in maximum and minimum temperatures follow, in broad terms, the corresponding well-documented mean temperature c ...
The first combined reconstruction of range-resolved wind velocities and O3 concns. is presented from the anal. of a single DIAL data set analyzed with a correlation method to det. wind speeds. The system can be used for the measurement of a unique componen ...
A new, parameter-free method, based on orthonormal wavelet expansions is proposed for calculating the principal time scale of coherent structures in atmospheric surface layer measurements. These organized events play an important role in the exchange of he ...
A combined measurement of O3 concn. and wind speed by lidar is presented, which permits a flux detn. of this pollutant. Measurements were obtained using a shot per shot differential absorption lidar (DIAL) system in which each return is recorded, stored, a ...
Previous work has identified bottom currents as a significant source of turbulence in stratified lakes. Sills may therefore be a major factor determining overall turbulent diapycnal (vertical) exchange in lakes with multi-basin hypolimnia. In order to inve ...
The artificial tracer sulphur hexafluoride (SF6) has been used to study the density-driven deep water exchange between two sill-separated basins of Lake Lucerne, Gersauersee and Urnersee. The sources of the density gradients between the two basins are (1) ...
Orthonormal wavelet expansions are applied to surface-layer measurements of vertical wind speed under various atmospheric stability conditions. The orthonormal wavelet transform allows for the unfolding of these measurements into space and scale simultaneo ...
