Abstract: Upper-air observations with kites, aircraft, and radiosondes were performed in the United States operationally since the 1890s. In this paper, the authors present a reevaluation of newly digitized monthly mean values from ...

Abstract: Historical radiosonde data are known to suffer from inhomogeneities. The first radiosonde intercomparison was made at Payerne, Switzerland, in 1954, and a major international effort to standardize the network, including ...

Abstract: Meteorological observations have been taken continuously at the summit of Mount Washington since 1932. Results of an analysis of the air temperature record over the 1935?2003 period show a statistically significant increase ...

Abstract: This work presents statistically reconstructed global monthly mean fields of temperature and geopotential height (GPH) up to 100 hPa for the period 1880?1957. For the statistical model several thousand predictors were used, ...

Abstract: Meteorological conditions have been recorded at the summit of Mount Washington, New Hampshire, (44°16?N, 71°18?W, 1914 m ASL) since November 1932. Use of consistent instrumentation allows analysis of humidity measurements ...
