“…The second flight of the CRyogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA-2) experiment on the ASTRO-SPAS (Wattenbach and Moritz, 1997) satellite took place in August 1997. CRISTA is an infrared limbsounding instrument that uses three simultaneously measuring telescopes to scan the atmosphere on a very dense horizontal grid.…”

“…CRISTA 2 measurements were taken during the period 8–16 August 1997. The basic configuration for CRISTA 2 was the same as for CRISTA 1 but during the second flight the outstanding maneuvering capability of the Astronomical Shuttle Pallet Satellite (ASTRO‐SPAS) carrier [ Wattenbach and Moritz , 1997] was used to extend the latitudinal coverage of the measurements. For most of the time, the ASTRO‐SPAS carrier satellite was continuously slewed backward and forward with constant angular velocity around the local vertical axis.…”

Geostrophic wind fields in the stratosphere and mesosphere from satellite data

[1] Daily maps of horizontally resolved zonal and meridional geostrophic wind fields in the altitude range of 20-90 km were obtained from the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) experiment during November 1994 and August 1997. Results are compared with zonal mean zonal winds from climatological sources and with assimilated data from standard analyses. Correlative data from groundbased and balloon-and rocket-borne measurements are used to validate the CRISTA winds. The comparisons show that geostrophic wind fields from high spatial resolution satellite-borne temperature measurements are a good approximation for the winds in the middle atmosphere up to mesopause heights. Therefore, they may be used as input for further modeling efforts particularly in the mesosphere, where no wind data from standard analyses are available.

“…During flight the CRISTA instrument is supported by the CRISTA-SPAS platform (Figure 1). CRISTA-SPAS is a shortlived satellite built to operate telescopes of the 1 m class during multiple missions [Wattenbach and Moritz, 1997]. It is equipped with telemetry/telecommand capability, a precise attitude control system, GPS receivers, tape recorders for data storage, batteries, etc.…”

Abstract. The Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) instrument was built to determine whether and to what extent small-scale structures in global trace gas distributions and in dynamics are present in the middle atmosphere. To achieve this, trace gases were measured in the middle infrared by the limb scan technique at the highest possible horizontal and vertical resolution. CRISTA uses three telescopes (i.e., three view directions) simultaneously, and has three grating spectrometers for the middle IR (4-14/xm) and one spectrometer for the far IR (15-71 /xm). The optics and detectors are cooled to cryogenic temperatures by supercritical helium or subcooled helium, respectively, in a double cryostat. An instrument overview is given, and the design guidelines are sketched. The CRISTA experiment was flown on the space shuttle STS 66 as part of NASA mission ATLAS 3 on November 3-14, 1994. Orbit altitude was 300 km, and inclination was 57 ø. A campaign of ground-based, balloon, and rocket validation and complementary measurements was performed simultaneously. The CRISTA instrument performed flawlessly. A horizontal resolution of 200 km x 650 km was achieved at the equator, with higher horizontal resolution at higher latitudes. A vertical resolution of 2.5 km (or better) was obtained. The middle atmosphere was found to be highly variable at scales of <1000 km in the stratosphere. Three streamers of tropic/ subtropic air extending to higher latitudes are described. Their meridional scale is -<1000 km, while the zonal scale is of the order of 10,000 km and more. The streamers appear to be typical of specific winter conditions and to play a role in meridional transport. At mesospheric heights a strong tidal temperature oscillation was observed which extended well into the lower thermosphere.
