Water vapour measurements during the second mission of the CRyogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) instrument are presented in the altitude regime 8–20 km. Mixing ratios are shown on isentropic surfaces (300–50

The “wave turbopause” is defined as the mesospheric altitude level where the temperature fluctuation field indicates a substantial increase in wave amplitudes in the vertical direction. The turbopause altitude is analyzed on the basis of four yea

Upper mesosphere temperatures have been derived from hydroxyl near-infrared emissions at Wuppertal (51°N, 7°E) for many years. Recently a strong increase of temperature fluctuations was observed which forced a change of our data evaluation algorith

Global temperature measurements are available from CRISTA (CRyogenic Infrared Spectrometers and Telescopes for the Atmosphere) and from SABER (Sounding of the Atmosphere using Broadband Emission Radiometry) up to 110 km . Standard deviation from zona

Similarities of middle atmosphere structures are analyzed on the basis of CRISTA 1 and SABER data which extend from the upper troposphere up into the lower thermosphere. An event of planetary wave breaking is identified that leads to the formation of

Summer duration (SD) is defined here as the time interval between spring and autumn turn around of zonal winds in the stratosphere. SD long-term trends are obtained from analysis of middle stratosphere NCEP and ECMWF data. They are found to be depend

During the second mission of the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) from August 8 to 16, 1997, over 45,000 altitude profiles of infrared spectra were collected. A variety of atmospheric trace gases have been r

Zonal asymmetries are frequently seen in stratospheric temperature or trace gas fields as surf zones, streamers, filaments etc. They are also seen as very small-scale fluctuations, the intensity of which varies with longitude. Similar structures migh

In two separate orbital campaigns (November, 1994 and August, 1997), the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) instrument acquired global stratospheric data of high accuracy and high spatial resolution. The stand

The Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) experiment aboard the Shuttle Pallet Satellite (SPAS) was successfully flown in early November 1994 (STS 66) and in August 1997 (STS 85). This paper focuses on the first
