Recent Jimsphere/Jimsonde measurements of tropospheric temperature profile spectra in the wavelength band 50 ≤ λ ≤ 2000 meters above the atmospheric boundary layer, taken over Cape Kennedy, Florida, are summarized. The results suggest that the spectra can be represented in the nondimensional form (ωg/σw)ϕ(k)/σT2 = S(K), where ϕ(k) is the temperature profile spectrum at wave number k, ωg is the Brunt‐Väsälä frequency, σw, and σT denote the standard deviations of the vertical velocity and temperature profiles, and S is a universal function of nondimensional wave number K = kσw/ωg. As K → ∞, the results suggest that S(K) ∼ K−1, whereas, for intermediate values of K ∼ O (10−2), S(K) ∼ K−3.
