[{"@context":"http:\/\/schema.org\/","@type":"Dataset","name":"Stockholm Historical Weather Observations \u2014 Air pressure","description":"Data for air pressure at the old astronomical observatory in Stockholm since 1756 are provided. Over time, different barometers have been used and measurements have been made in different units.\r\n\r\nEfforts have been made to convert all individual observations to hPa reduced to 0\u00b0C, normal gravity and sea level back to 1756. Homogenization of the record has been done by applying adjustments such that the long term trend agrees with other long air pressure measurements in Northern Europe.\r\n\r\nData are divided into two separate datasets: (i) individual barometer observations in original units, (ii) daily sea level pressure data, both with and without the homogenization. Despite the efforts made, the homogenized record is judged to not reliably show long-term trends in air pressure over the entire period, but the short term day-to day changes are likely rather accurate.\r\n\r\n\r\n","url":"http:\/\/bolin.su.se\/data\/?n=stockholm-historical-pressure","keywords":["Atmosphere","Weather observations","Air pressure","Daily data","Monthly data","Early instrumental data","Homogenized data","Sweden","Stockholm","Earth science > Atmosphere"],"creator":{"@type":"Person","name":"Anders Moberg"},"citation":"Moberg A, Bergstr\u00f6m H, Ruiz Krigsman J, Svanered O. 2002: Daily air temperature and pressure series for Stockholm (1756\u20131998).
