Abstract : Arrays of means and standard deviations of temperature and density for 2-km intervals of altitude up to 30 km, together with inter- and intra-level coefficients of correlation of density with density, temperature with temperature, and temperature with density, are presented for midseason months at four locations. Temperature and density at the same level are, in general, negatively correlated at altitudes below 30 km. A level of minimum seasonal and latitudinal temperature variability occurs between 12 and 14 km. Seasonal temperature variability is largest near the earth's surface, and the latitudinal variability is greatest between 14 and 17 km. Density variability is least near 8 km, the isopycnic level. A level of maximum seasonal and latitudinal density variability occurs between 12 and 14 km. Means and standard deviations of surface pressure and coefficients of correlation between surface pressure and temperatures at levels up to 30 km are presented and discussed. An examination of the relationship between the standard deviation of surface pressure and the coefficients of variation of density at the level of maximum variability indicates that the variation of surface pressure is not a good index of variations in the vertical density distribution.
