[{"title":"Stockholm Historical Weather Observations","summary":"Weather observations have been made continuously at the old astronomical observatory in Stockholm since 1754. This is one of the world's longest records of meteorological observations, and probably the very longest continuous record from one and the same local site. Thus, the Stockholm observation series provides invaluable information about weather and climate change for more than 260 years.\r\n\r\nIn the 18th century, the weather observations were made by astronomers as a part of their studies of the universe. Today, the observation site in Stockholm is a weather station within the national station network managed by the Swedish Meteorological and Hydrological Institute (SMHI).\r\n\r\nThis data collection contains observations of air temperature, air pressure and cloud amount together with calculated daily and monthly averages of air temperature since 1756. Observed maximum snow depth each winter since 1904\/05 is also included.","citations":"Moberg A. 1996: Temperature variations in Sweden since the 18th century.
