The first Research Centre in Greece and the Balkans
The Institute for Environmental Research and Sustainable Development (IERSD) is one of three Institutes of the National Observatory of Athens, the first Research Centre in Greece and the Balkans. Initially named as Meteorological Institute (MI), it was established in 1846 while the first meteorological observations began in 1858. IERSD holds the longest and most complete climatological records in Greece, spanning a 150-yrs period. It constituted the first official Meteorological Service of Greece, operating almost all meteorological stations of the existing network until 1931, when the National Meteorological Service was founded.
Besides climatic records, IERSD holds a historical record of atmospheric ozone data, monitored from 1900 to1940, which is unique for Southeastern Europe. Milestone to the evolution of the Institute was the study of atmospheric pollution, well before its evident appearance in Athens, through the systematic monitoring of classical pollutants with a network of six stations. The network was passed to the Ministry of the Environment in 1984 and formed the basis of the National Network for the Monitoring of Atmospheric Pollution.
