The "Étude et Simulation de la QUalité
de l'air en Ile de France" (ESQUIF) project is the first integrated project
dedicated to the study of the processes leading to air pollution events over the
Paris area. The project was carried out over two years (summer 1998 to winter
2000) to document all types of meteorological conditions favourable to air
quality degradation, and in particular to photo oxydant formation. The goals of
ESQUIF are (1) to improve our understanding of the relevant chemical and
dynamical processes and, in turn, improve their parametrizations in numerical
models, and (2) to improve and validate existing models dedicated to pollution
analysis, scenarios and/or forecasting, by establishing a comprehensive and
thorough database. We present the rationale of the ESQUIF project and we
describe the experimental set-up. We also report on the first experiments which
took place during the summer of 1998 involving surface networks, and remote
sensing instruments as well as several aircraft. Focusing on three days of
August 1998, the relative contributions of long-range transported and
locally-produced ozone to the elevated ozone concentrations observed during this
period are discussed and chemistry-transport model preliminary results on this
period are compared to measurements.
