Séminaire du CEREA - 6 décembre 2004

Improvement of the Mobile Source Emission Inventory by means of Inverse Modeling in Santiago de Chile

The city of Santiago suffers severe air pollution, which is attributed mainly to mobile sources. The complex topography and the prevailing meteorological conditions (e.g, subtropical high and subsidence inversion) inhibit the dispersion of pollutants.
Efforts have been made to overcome these problems, and significant improvements have been achieved. However, as in many other mega-cities, there is a need of more accurate emission inventories and models to deal with transportation sources.
In this seminar, we show preliminary results of the application of two inverse modeling techniques, i.e, best unbiased linear estimator (BLUE) and adjoint, to assess emissions of carbon monoxide (CO) from mobile sources in Santiago de Chile using available observations as constraints. Our aim is to improve the official emission inventory and strengthen our modeling capabilities.

Le séminaire aura lieu dans la salle de réunion du CEREA B220 à 11h00.
