N1 - Funding Information:
Through the cooperative projects CLU and TUE, the UBL/CLU-ESCO-MPTE experiment was funded by the CNRS programmes for atmospheric dynamics (PATOM) and remote sensing from space (PNTS). Bernard Cros and the ESCOMPTE committees deserve warm thanks. As an associate project it also benefited from ESCOMPTE funding. Part of the funding of the North American participants was provided by the National Science Foundation (NSF), the Natural Sciences and Engineering Research Council of Canada (NSERC) and the Canadian Foundation for Climate and Atmospheric Science (CFCAS). The BDTopo urban database was provided by the Institut Géographique National (IGN). The RASS-sodar profiler and one sonic anemometer were made available by Alliance Technologies, and the stand-alone Vertical Ozone Profiler by Elight Laser System GmbH. Trade and company names are given for the benefit of the reader and do not imply endorsement of the product or company by the authors. The authors would like to thank A. Delaval, G. Beffrey, M. Chiriaco, C. Boitel, P. Del-ville, and B. Romand for their assistance with the TWL; F. Parmigiani (University of Modena) who collected the NOAA-AVHRR images; P. Jackson and C. Walsh for field assistance at the CAA site; J. Jagoury, Y. Lorin and D. Gaudin (ECN), Y. Tétard and Y. Queveau (CSTB); and Sir-iatech (Villeneuve d’Ascq, France) for assistance and support.

N2 - The UBL/CLU (urban boundary layer/couche limite urbaine) observation and modelling campaign is a side-project of the regional photochemistry campaign ESCOMPTE. UBL/CLU focuses on the dynamics and thermodynamics of the urban boundary layer of Marseille, on the Mediterranean coast of France. The objective of UBL/CLU is to document the four-dimensional structure of the urban boundary layer and its relation to the heat and moisture exchanges between the urban canopy and the atmosphere during periods of low wind conditions, from June 4 to July 16, 2001. The project took advantage of the comprehensive observational set-up of the ESCOMPTE campaign over the Berre-Marseille area, especially the ground-based remote sensing, airborne measurements, and the intensive documentation of the regional meteorology. Additional instrumentation was installed as part of UBL/CLU. Analysis objectives focus on (i) validation of several energy balance computational schemes such as LUMPS, TEB and SM2-U, (ii) groundtruth and urban canopy signatures suitable for the estimation of urban albedos and aerodynamic surface temperatures from satellite data, (iii) high resolution mapping of urban land cover, land-use and aerodynamic parameters used in UBL models, and (iv) testing the ability of high resolution atmospheric models to simulate the structure of the UBL during land and sea breezes, and the related transport and diffusion of pollutants over different districts of the city. This paper presents initial results from such analyses and details of the overall experimental set-up.
