FIRST RESULTS FROM BUBBLE I: PROFILES OF FLUXES IN THE URBAN ROUGHNESS SUBLAYER

摘要

The Basel Urban Boundary Layer Experiment (BUBBLE) brings together activities in modeling, remote sensing and turbulence measurements, in order to increase the understanding of exchange processes in urban areas (Rotach, 2002). As part of the project, a field experiment is currently carried out in the city of Basel (Switzerland) with continuously operated micro-meteorological surface measurements at different sites from November 2001 to July 2002. This presentation focuses on turbulence profiles, measured during the first three months of operation.
