Scale lengths, defined in four different ways, have been derived from previously reported spectra and autocorrelations of vertical air velocity component measured from an aircraft at heights between 10 and 1,310 m. Below about 200 m the scale length increases with height more slowly than linearly and it does not seem possible to attribute this result to stability effects. At higher levels, no systematic height dependence can be shown. The results offer some support for the suggestion that the scale length is greater in lapse conditions than otherwise.
