Abstract : Statistical air density data of five locations on the northern hemisphere were presented in an earlier report. (Alfuth, W. H., Some Features of Air Density Profiles up to the Middle Stratosphere, ABMA Report No. RR-TR-61-4, 10 Oct 61). Those statistical parameters of air density at constant altitude levels were derived from frequency distributions at constant pressure levels. The tacit assumption was made that the height of an isobaric surface does not change with time at a particular station, since all air density values of a certain pressure level had been assigned the mean altitude of that level when interpolating for fixed altitude levels. The purpose of this paper is to delineate the different types of errors possible in upper air climatology with particular emphasis on deficiencies of the previously presented air density data.
