Energy and radiation balance of a central European city
Andreas Christen,Roland Vogt +1 more
TL;DR: In this paper, the results from an experimental network of seven energy balance stations in and around a European city were presented, which allowed the simultaneous comparison of urban, suburban, and rural energy balance partitioning during one month of summertime measurements.
Journal ArticleDOI
BUBBLE - an urban boundary layer meteorology project
Mathias W. Rotach,Mathias W. Rotach,Roland Vogt,Christian Bernhofer,Ekaterina Batchvarova,Andreas Christen,Alain Clappier,B. Feddersen,Sven Gryning,Giovanni Martucci,Helmut Mayer,Valery Mitev,Timothy R. Oke,Eberhard Parlow,Hans Richner,Mattias Roth,Yves-Alain Roulet,Dominique Ruffieux,Jennifer Salmond,Michael Schatzmann,James A. Voogt +20 more
TL;DR: The Basel UrBan Boundary Layer Experiment (BUBBLE) was a year-long experimental effort to investigate in detail the boundary layer structure in the City of Basel, Switzerland as discussed by the authors.
Journal ArticleDOI
The energy balance experiment EBEX-2000. Part I: Overview and energy balance
Steven P. Oncley,Thomas Foken,Roland Vogt,W. Kohsiek,H.A.R. Debruin,Christian Bernhofer,Andreas Christen,Eva van Gorsel,David Grantz,Christian Feigenwinter,Irene Lehner,Claudia Liebethal,Heping Liu,Matthias Mauder,Andrea Pitacco,Luís Frölén Ribeiro,Tamás Weidinger +16 more
TL;DR: The Energy Balance Experiment (EBEX-2000) as discussed by the authors studied the ability of state-of-theart measurements to close the surface energy balance over a surface (a vegetative canopy with large evapotranspiration) where closure has been difficult to obtain.
Journal ArticleDOI
The Surface Urban Energy and Water Balance Scheme (SUEWS): Evaluation in Los Angeles and Vancouver
TL;DR: In this paper, an urban energy and water balance model is presented which uses a small number of commonly measured meteorological variables and information about the surface cover rates of evaporation-interception for a single layer with multiple surface types.
Journal ArticleDOI
Validation of modeled carbon-dioxide emissions from an urban neighborhood with direct eddy-covariance measurements
Andreas Christen,Nicholas C. Coops,Ben Crawford,Ronald Kellett,Kate Liss,Kate Liss,Inna Olchovski,Thoreau Rory Tooke,M. van der Laan,James A. Voogt +9 more
TL;DR: In this paper, the authors presented detailed maps of modeled local carbon-dioxide emissions for a 4 km 2 residential neighborhood in Vancouver, BC, Canada and validated the emissions from an urban area against direct eddy-covariance flux measurements.
