Historic Weather Station, Prague, Czech Republic Poster

"Historic Weather Station, Prague, Czech Republic" by Catherine Sherman. In 1752, the first regular meteorological measurement was initiated in the Clementinum complex in Prague, Czech Republic, and it has been continued to this day. The Climatological station Prague Clementinum (station number WMO 11514) - the oldest meteorological measuring station in the Czech Republic -- is considered unique in the whole Central Europe. Since 1775, measurements have been taken every day. The Clementinum (Czech: Klementinum) is a historic complex of buildings in Prague which houses the National Library of the Czech Republic. In Clementinum there are two meteorological boxes – slat, which is shown here, and iron-plate. The slat box measures temperature and air moisture on the first floor of north side of south annex. The iron-plate box is on the roof flat at east annex where a technical library is located. The amount of rainfalls and duration of sunshine is being noted every day by the help of an apparatus called heliograph.
