Validation of Thermosphere Ionosphere Mesosphere Energetics and Dynamics/Sounding of the Atmosphere using Broadband Emission Radiometry (TIMED/SABER) v1.07 ozone at 9.6 μm in altitude range 15–70 km

“…A number of satellite missions have been launched within the last 7 years to measure ozone and other parameters including, for example, POES/SBUV/2 (solar backscatter ultraviolet) [ Bhartia et al , 1996], ENVISAT/MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) from ESA (European Space Agency) [ Fischer et al , 2000], AURA/MLS (Microwave Limb Sounder) [ Waters et al , 2006], AURA/HIRDLS (High Resolution Dynamics Limb Sounder) [ Dials et al , 1998], and TIMED/SABER (Sounding of the Atmosphere Using Broadband Emission Radiometry) [ Russell et al , 1999] from NASA. Obtaining data at altitudes above 50 km is either marginal for most of these missions because it is near their upper limit of vertical coverage, or the vertical resolution is somewhat coarse (6–7 km).…”

A new method for the validation of the GOMOS high resolution temperature profiles products

“…few meters), but they are limited to regional studies and the related datasets can be sparse in time. In particular, balloon-borne experiments provide measurements of temperature profiles from ground up to the maximum altitude reached by the balloon, which is usually at ~30-35 km [Durre et al 2006], with a vertical resolution varying between 5 and 50 m. On the other hand, spaceborne experiments, such as the Microwave Limb Sounder (MLS) [Wu and Waters 1996], the Halogen Occultation Experiment (HALOE) on-board Upper Atmosphere Research Satellite (UARS) [Borchi et al 2005], the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) [Ridolfi et al 2007] on-board EN-VISAT, the High Resolution Dynamics Limb Sounder (HIRDLS) on the AURA spacecraft [Dials et al 1998], the Sounding of the Atmosphere by Broadband Emission Radiometry (SABER) on TIMED (Thermosphere Ionosphere Mesosphere Energetics Dynamics) satellite [Kumar et al 2008] and GPS radio occultation technique [Kursinski et al 1997, Schreiner et al 2007] as the Constellation Observing System for Meteorology Ionosphere and Climate (COSMIC/FORMOSAT-3) satellite [Kishore et al 2009], have been designed to retrieve temperature profiles in a wide altitude range, from troposphere to mesosphere, but with a vertical resolution much lower when compared to that of balloon sondes. An exception is represented by the High Resolution Temperature Profile (HRTP) of GOMOS (Global Ozone Monitoring by Occultation of Stars) tempera-ture and density products [Bertaux et al 2010], which have a vertical sampling of few tens of meters and an estimated vertical resolution of about 250 m (see Sofieva et al [2007aSofieva et al [ , 2007b).…”
