Abstract

Applications of Adjoint Modelling in Urban Air Pollution Guest contribution Robert Vautard\ Matthias Beekmann^, Laurent Menut* and Mireille Lattuati^ ' Laboratoire de Meteorologie Dynamique, 24 rue Lhomond, 75231 Paris Cedex 05, France * Service d 'Aeronomie, Universite P&M Curie, Tour 15, 75252 Paris Cedex 05, France * ARIA Technologies S.A., Colombes, France Introduction In many instances in environmental sciences it is desirable to estimate the derivative of some physical time-evolving variables with respect to various parameters. Such is the case, for instance, for estimating the sensitivity of atmospheric pollutant concentrations to the anthropogenic emissions. The problem is made difficult by the strongly nonlinear relationship between them. The classical strategy consists in performing "twin s
