| Zusammenfassung |
| The aim of this paper is to compare two different modelling systems and to
evaluate their ability to simulate high values of ozone concentration in
typical summer episodes which take place in the north of Spain near the
metropolitan area of Barcelona. As the focus of the paper is the comparison
of the two systems, we do not attempt to improve the agreement by adjusting
the emission inventory or model parameters.
The first model, or forecasting system, is made up of three modules. The
first module is a mesoscale model (MASS). This provides the initial
condition for the second module, which is a nonlocal boundary layer model
based on the transilient turbulence scheme. The third module is a
photochemical box model (OZIPR), which is applied in Eulerian and Lagrangian
modes and receives suitable information from the two previous modules. The
model forecast is evaluated against ground base stations during summer 2001.
The second model is the MM5/UAM-V. This is a grid model designed to predict
the hourly three-dimensional ozone concentration fields. The model is
applied during an ozone episode that occurred between 21 and 23 June 2001.
Our results reflect the good performance of the two modelling systems when
they are used in a specific episode. |
