The Berlin stratospheric data series: cd documentation

The Berlin stratospheric data series contains temperature and geopotential height data on the 100, 50, 30, 10 mb pressure surfaces produced at the Meteorological Institute, Free University of Berlin, from radiosonde data and rocket observations. The data covers the northern hemisphere during the years 1957 to 2001 and is available on both a 10° x 10° and 5° x 5° grid. This data series is fully documented and contains remarks on summer, winter and annual trends and variability of the data, climatological monthly mean temperature and geopotential height at 30 mb, and intercomparisons with other data series. There are also sections on the quasi-biennial oscillation (QBO) and the global signal of the 11-year sunspot cycle in the stratosphere.
