Abstract
In this paper, the small-scale (<1 km) structure of temperature near the tropopause, as indicated by ozone concentration, is examined using data recorded during GALE from the NCAR Sabreliner. A systematic difference is observed in the temperature microstructure of the troposphere and stratosphere in qualitative agreement with evidence from VHF radar observations. Spectral distribution of the temperature variations also differs across the tropopause.
