Abstract : Subdivisions of the altitude range from surface to 25 km into four to eight layers are presented. These layer combinations were chosen to provide optimum average fit of the corresponding step functions to a combined set of individual air density profiles from the northern hemisphere. Separation into zones such as tropical, temperate, and arctic would render optimum layers different from the presented northern hemisphere combination. The investigation is based on evaluation of samples from the radiosonde stations Guam, Wiesbaden, and Fairbanks. The samples were selected to approximate closely the climatological frequency of occurence of density profiles. (Author)
