| Zusammenfassung |
| The European Academy (EURAC) and the Autonomous Province of Bozen/Bolzano have
started a new project for monitoring air quality in South Tyrol/Alto Adige. The project
is both scientific and operational. Starting from in-situ data of particulate matter
(PM) concentration and integrating them with remote sensing data, the aim of the
project is to develop a daily product for monitoring and assessing air quality in South
Tyrol.
South Tyrol is particularly interesting because of its orographic setting: the contrast
between the valleys at relatively low altitude and the steep slopes of the mountains causes an
accumulation of PM in the valleys, mainly in winter when inversions are frequent. Besides
these natural factors, the presence of small-medium towns and of the Brennero motorway
represents huge sources of pollution for the region which can become hazardous for human
health.
In this paper, we first present the structure and objective of the aforementioned project,
and second, results obtained from the time series analysis from 2005 to 2008 of the aerosol
optical depth (AOD) product from NASA’s MODIS instruments and the PM data provided by
the Province are shown. Analysing the extreme events statistics of PM concentration, it is
possible to observe a negative trend in the number of days in which the PM concentration is
over the threshold of 50μg/m3. The source of this trend is investigated using different data
sets and approaches. |
