This was made in order to assess DOAS performance in a complicated area in terms of sources variety, terrain complexity and meteorological conditions. Measurements of aromatic hydrocarbon substances (benzene, toluene, styrene and xylene) are also presented for air quality purposes. Results between the conventional station and the DOAS system indicated the existence of significant correlations among some of the monitored trace gases, confirming this way the strong compatibility between the two systems. The low values of sulfur dioxide especially during the winter were attributed to the absence of central heating in the most of the buildings due to the use of district heating provided by the Greek Public Power Corporation. The averaged annual benzene and daily toluene concentrations exceeded their legislated limits. Meteorological parameters remain vital in the development of a clear understanding in DOAS performance due to its ability to cover a wide spatial scale over the open path length.</p></abstract><publication_date><month>04</month><day>29</day><year>2013</year></publication_date><pages><first_page>161</first_page><last_page>168</last_page></pages><publisher_item><identifier id_type="pii">498</identifier></publisher_item><doi_data><doi>10.30955/gnj.000498</doi><timestamp>1714156700</timestamp><resource>https://journal.gnest.org/publication/498</resource></doi_data></journal_article></journal></body></doi_batch> </div>
