International Recognition for the Meteorology in Bulgaria
Three meteorological stations in the network of the National Institute of Meteorology and Hydrology are among the 70 stations worldwide which have been working for more than a century without interruption. They have been recognized by the United Nations World Meteorological Organization as part of the world cultural and scientific heritage. These are the stations “Obraztsov Tchiflik” founded in 1889, “Sliven” founded in 1890 and “Knezha” founded in 1910. The stations did not stop working even during the wars of the first half of the 20th century.
