Abstract: AbstractSurface-layer-resolving large-eddy simulations (LESs) of free-convective to near-neutral boundary layers are used to study Monin?Obukhov similarity theory (MOST) functions. The LES dataset, previously used for the ...

Abstract: The diurnal wind system of the Kali Gandaki Valley in Nepal was explored in September and October 1998 in a field campaign using pilot balloons as the main observational tool. This valley connects the Plateau of Tibet with ...

Abstract: irect covariance flux (DCF) measurements taken from floating platforms are contaminated by wave-induced platform motions that need to be removed before computation of the turbulent fluxes. Several correction algorithms ...

Abstract: A versatile two-axis tracking system with datalogger is presented. It is designed with regard to high pointing accuracy, high torque and mechanical load, high accuracy of the data acquisition, extended weather resistance, ...

Abstract: n this study, it is demonstrated how temperature, humidity, and wind profile data from the lower troposphere obtained with a lightweight unmanned aerial system (UAS) can be used to improve high-resolution numerical weather ...

Abstract: In 1998 a field campaign has been conducted in the north?south-oriented Kali Gandaki valley in Nepal to explore the structure of its extreme valley wind system. Piloted ballon (pibal) observations were made to map the ...

Abstract: In July and August 2003 a field campaign was conducted to explore the diurnal circulation of the Bolivian Altiplano. Vertical soundings by remote-controlled aircraft yielded profiles of temperature, pressure, and humidity ...
