| Zusammenfassung |
| During the months of June and July 2013, over the Euro–Mediterranean area,
the ADRIMED (Aerosol Direct Radiative Impact on the regional climate in the MEDiterranean
region) project was dedicated to characterize the ozone and aerosol
concentrations in the troposphere. It is first shown that this period was not
highly polluted compared to previous summers in this region, with a moderate
ozone production, no significant vegetation fire events and several
precipitation periods scavenging the aerosol. The period is modeled with
the WRF (Weather Research and Forecasting) and CHIMERE models, and their ability to quantify the observed pollution
transport events is presented. The CHIMERE model simulating all kinds of
sources (anthropogenic, biogenic, mineral dust, vegetation fires); the
aerosol speciation, not available with the measurements, is presented: during
the whole period, the aerosol was mainly constituted by mineral dust, sea
salt and sulfates close to the surface and mainly by mineral dust in the
troposphere. Compared to the AERONET (Aerosol Robotic Network) size distribution, it is shown that the
model underestimates the coarse mode near mineral dust sources and
overestimates the fine mode in the Mediterranean area, highlighting the need
to improve the model representation of the aerosol size distribution both
during emissions, long-range transport and deposition. |
