Journal ArticleDOI
Application of a multiscale, coupled MM5/chemistry model to the complex terrain of the VOTALP valley campaign
Georg Grell,Stefan Emeis,William R. Stockwell,Thomas Schoenemeyer,Renate Forkel,John Michalakes,Richard Knoche,Winfried Seidl +7 more
TL;DR: In this paper, a coupled complex meteorology/chemistry model has been used to simulate the flow field and the concentration fields of atmospheric pollutants in Alpine valleys during the VOTALP (Vertical Ozone Transports in the ALPs) Valley Campaign in southern Switzerland.
Journal ArticleDOI
Surface-based remote sensing of the mixing-layer height a review
TL;DR: In this article, the authors summarized and compared the available methods for the determination of the mixing-layer height from surface-based acoustic, optical and electro-magnetic remote sensing.
Journal ArticleDOI
Atmospheric boundary-layer structure from simultaneous SODAR, RASS, and ceilometer measurements
TL;DR: In this article, a comparison of the determination of boundary-layer structures by a SODAR, by a RASS, and by a ceilometer is presented, focusing on 3 days with an evolution of a convective boundary layer over a larger city in Germany.
Journal ArticleDOI
Secondary effects of urban heat island mitigation measures on air quality
TL;DR: In this article, a mesoscale chemical transport model is used to investigate the impact of urban greening and highly reflective surfaces on the concentrations of primary (CO, NO) as well as secondary pollutants inside the urban canopy.
Journal ArticleDOI

TL;DR: The first direct in situ measurements of the existence and shape of large wind farm wakes by a specially equipped research aircraft in 2016 and 2017 confirm wake lengths of more than tens of kilometres under stable atmospheric conditions, with maximum wind speed deficits of 40%, and enhanced turbulence.
