Abstract

Detectability of gravity waves (GW) for a limb sounding experiment is investigated: Limb radiances emitted from a modeled GW field are calculated. Horizontal and vertical wavelengths of the GW are varied. Distinguishable amplitudes are found in altitude radiance profiles, even if wavelengths are short compared to the weighting function of radiative transfer. Altitude profiles of temperature retrieved from CRISTA limb radiances are analysed for small vertical scale waves. Because of their short spatial scales, they are tentatively interpreted here as GW. Amplitudes are deduced from single height profiles. This leads to a high resolution spatial distribution of GW activity. Results for the first CRISTA flight are presented and compared to recent satellite-based measurements of GW.
