ABSTRACT

A major use of SODAR and RASS technology is in monitoring and understanding the atmospheric boundary layer in relation to air pollution and dispersion modeling. Traditionally it has been difficult for these instruments to work effectively in closely built-up urban areas, because of echoes from buildings and because of impact on residents, but this is changing as the acoustic design of the instruments improves. We give here a few results from Salfex, an urban “street canyon” momentum and heat flux study in Salford, Greater Manchester, UK, which was led by Janet Barlow of Reading University (Barlow et al., 2007).
