Abstract
The estimation of the source pollutant strength is a relevant issue for atmospheric environment. This characterizes an inverse problem in the atmospheric pollution dispersion studies. In the inverse analysis, a timedependent pollutant source is considered, where the location of such source term is assumed known. The inverse problem is formulated as a nonlinear optimization approach, whose objective function is given by the leastsquare difference between the measured and simulated by the mathematical model, pollutant concentration, associated with a regularization operator. The forward problem is addressed by a Lagrangian model, and a quasiNewton method is employed for minimizing the objective function. The secondorder Tikhonov regularization is applied and the regularization parameter is computed by using the Lcurve scheme. The inverseproblem methodology is verified with data from the tracer Copenhagen experiment.
