CRISTA: Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere


CRISTA temperature perturbations provide information on shorter vertical wavelength gravity waves than the MLS [Preusse et al., 1999]. The figure above shows largest amplitudes for short vertical wavelength waves nearest the equator. This dominant pattern can be related to the slow vertical group velocities of the short vertical wavelength and low frequency waves that occur near the equator [Alexander, et al., 2001; Ern et al., 2004].
