Abstract
During 9 November 1994, the CRyogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) experiment measured vertical profiles of temperature up to an altitude of 120 km. Temperatures above 75 km are retrieved from 15 μm CO2 emissions, accounting for the deviation from the local thermodynamical equilibrium (non‐LTE, NLTE). This study presents the first amplitude and phase measurements of global temperature tides in a region of Earth's atmosphere where prior to CRISTA no daytime and nighttime temperature measurements were available. The migrating and 8 nonmigrating components of the diurnal tide are analyzed from 75–120 km and at 7.5°N. Combined amplitudes exceed 80 K with the nonmigrating components dominant above ∼90 km.
