Mean daily PM<sub>10</sub> concentrations between 2001 and 2018, from the monitoring station established in Volos is used. The aim is to investigate the seasonality, intraweek, intraday, weekend effect and spatial variations of the PM<sub>10</sub> concentrations as well as trends of data, are statistically studied. The work may assist the formation of PM<sub>10</sub> forecasting models of hourly, daily, weekly, monthly and annual horizon. Significant changes observed in PM<sub>10</sub> series concentrations dusing the years were found. This may be due to economic and social reasons but also due to measures taken by the state so as to be harmonised with the European Directives concerning the protection of public health and the atmospheric environment of the European Union (EU) members.</div><div> <div> <div>Keywords: </div> PM<sub>10</sub> data series; statistical analysis; Volos; Greece</div> </div>

Research paper thumbnail of Trends and variability of precipitation within the Mediterranean region, based on Global Precipitation Climatology Project (GPCP) and ground based datasets

Besides, the trends of sea surface temperature (SST) and sea surface pressure (SLP) from NCEP/NCAR Reanalysis are investigated in order to explain the observed trends in precipitation. On the other hand, the influence of atmospheric circulation, by means of North Atlantic Oscillation Index (NAOI), on the precipitation variability is presented. The results showed that an anti-correlation, (statistically significant at 95% confidence level), exists between precipitation (mm/day), rain days and NAOI, within the rain season of the year (October-March), against a positive correlation within the dry season (April-September). Concerning the temporal distribution of precipitation, decreasing trends appear throughout the Mediterranean, especially in the eastern parts and within the rain season of the year, while these trends are positive within the dry period, but statistically insignificant (95% confidence level). Increasing trends of SST for both rain and dry season, and decreasing trends of SLP appear.

Research paper thumbnail of Food and climate in Greece. Their relationship from the antiquity to the 20th century

Abstract of EGU 2019 presentation, 2019

From these three famous S the first two have been present in the region since the antiquity and the third was a food invention of the twentieth century, the Greek version of what it is called fast (and cheap) food. The climatic studies, by foreign and Greek scientists, which started in a professional level since the mid-19th century have proved, beyond any question, that the prevailing weather in the Southern Balkan Peninsula has not changed significantly for about forty centuries, despite the fluctuations which have been appeared in certain periods. In our paper we aim to discuss the connection between food and weather in the Greek speaking lands during three distinctive periods: the antiquity, the Byzantium and the period of contemporary Hellenism until the 1970s. Since this decade, other cultural, political and social parameters have altered significantly the dietary habits of the Greeks, though in some extent, especially in the countryside and the lower social classes, these changes are not so marked as in the urban centres and the middle and upper classes. Our presentation will be based on visual and textual data, like representations in pottery and paintings and narratives in prose or poems. It is our scope to examine whether or not under relatively stable weather conditions, which undoubtedly are a very important factor for the formation of a general national identity, food could be used as a tracer to investigate the so called "fine structure phenomena" like the identities of certain social groups and certain local populations. Finally, having used Greece as a case study we may propose a theoretical scheme for the use of food as a climate indicator.
