Eastern Mediterranean air temperature follows the northern hemisphere (NH) secular trend till 1970s, while the NH warming of the last 30 years is not noticeable in the eastern Mediterranean till 1990s. National Observatory of Athens (NOA) meteorological time series start from the last decades of the 19th Century, therefore are at first suitable for detection of long term trends in the region. In this study we investigate whether the abrupt increase of the NOA air temperature time series, which appears during the last few years, is the finger-print of the broader scale climatic change or it is a discontinuity in the record of urban effect or of station’s problems origin. It is shown that NOA air temperature records display a statistically significant discontinuity attributable to change of the station thermometers on 1995 and therefore NOA records must be treated with caution for long term air temperature trends detection. </p></abstract><publication_date><month>04</month><day>29</day><year>2013</year></publication_date><pages><first_page>107</first_page><last_page>116</last_page></pages><publisher_item><identifier id_type="pii">436</identifier></publisher_item><doi_data><doi>10.30955/gnj.000436</doi><timestamp>1713419129</timestamp><resource>https://journal.gnest.org/publication/436</resource></doi_data></journal_article></journal></body></doi_batch> </div>
