| Zusammenfassung |
| There have been relatively few tracer experiments carried out that have
looked at vertical plume spread in urban areas. In this paper we present
results from two tracer (cyclic perfluorocarbon) experiments carried out in
2006 and 2007 in central London centred on the BT Tower as part of the
REPARTEE (Regent's Park and Tower Environmental Experiment) campaign. The
height of the tower gives a unique opportunity to study vertical dispersion
profiles and transport times in central London. Vertical gradients are
contrasted with the relevant Pasquill stability classes. Estimation of
lateral advection and vertical mixing times are made and compared with
previous measurements. Data are then compared with a simple operational
dispersion model and contrasted with data taken in central London as part of
the DAPPLE campaign. This correlates dosage with non-dimensionalised
distance from source. Such analyses illustrate the feasibility of the use of
these empirical correlations over these prescribed distances in central
London. |
