The CRISTA instrument was designed to measure global data sets of
temperature and trace gases with high spatial resolution. The first CRISTA flight occurred
during early November 1994. During this seven day mission CRISTA took 50000 height
profiles. The vertical sampling of most of these profiles was 1.5 km. Fast helium cooled
infrared detectors allow measurements of high precision and the narrow field of view is
well suited to resolving small vertical structures. Thus, it is possible to deduce
amplitudes of small spatial scale waves from the CRISTA data. Temperature profiles
measured in the lee of the Andes are discussed in terms of vertical and horizontal
wavelength. As predicted from two-dimensional radiance calculations, horizontal
wavelengths of the order of the weighting function are detectable by the CRISTA
instrument. Evidence is found that waves with even shorter horizontal wavelength can be
