The Berlin dataset consists of 35 years of daily (every two days in summer) geopotential height and temperature fields at 50, 30 and 10hPa in the northern hemisphere. The hemispheric analyses were produced in real time by a subjective analysis technique,using the 00UT radiosonde reports from the observational network, by a team of experienced meteorologists. Both geostrophic and hydrostatic balance were assumed in the analysis procedure, and the wind observations were given a high priority. The imposition of these balance conditions ensures a consistent dataset; further, temporal continuity is assured by meteorological inspection. Note that these balance conditions can result in, say, temperatures which deviate from the local radiosonde reports, which include meso-scale structures as well as any random or systematic observational errors. The Berlin analyses thus represent the synoptic-scale structure of the lower and middle stratosphere.
Daily Plots of the stratosphere
The data are available in regular northern hemispheric latitude-longitude grids:
geopotential height from November 1964 to June 2001,
temperatures from July 1965 to June 2001.
In summer Berlin Data are available only on even numbered days. Requests for odd numbered days will be linear interpolated!
After 1971 the 10hPa data are available only from September through February!
The archive does not contain 10hPa data later than November 1997!
