“…30. As reported in Remsberg et al (2008), the SABER profiles over this altitude range have approximately 1-2 K precision but may be biased 2-3 K warm in the lower stratosphere and 1-3 K cold in the upper stratosphere to lower mesosphere (for conditions where the stratopause is in the typical 1 mb region). As stated previously, SOFIE T (P ) has approximately 2 K uncertainty over this altitude range so the agreement seen in Fig.…”

Abstract. Measurement of atmospheric temperature as a function of pressure, T (P ), is key to understanding many atmospheric processes and a prerequisite for retrieving gas mixing ratios and other parameters from solar occultation measurements. This paper gives a brief overview of the solar occultation measurement technique followed by a detailed discussion of the mechanisms that make the measurement sensitive to temperature. Methods for retrieving T (P ) using both broadband transmittance and refraction are discussed. Investigations using measurements of broadband transmittance in two CO 2 absorption bands (the 4.3 and 2.7 µm bands) and refractive bending are then presented. These investigations include sensitivity studies, simulated retrieval studies, and examples from SOFIE.

“…Therefore, it is possible to compare HIRDLS random errors directly with the estimated gravity wave temperature variances. For SABER, the temperature precision was estimated by Remsberg et al (2008), and values are also given on the SABER website at http://saber.gats-inc.com/temp_errors.php. In Table 2 we have summarized these SABER precision estimates.…”

Abstract. Gravity waves are one of the main drivers of atmospheric dynamics. The spatial resolution of most global atmospheric models, however, is too coarse to properly resolve the small scales of gravity waves, which range from tens to a few thousand kilometers horizontally, and from below 1 km to tens of kilometers vertically. Gravity wave source processes involve even smaller scales. Therefore, general circulation models (GCMs) and chemistry climate models (CCMs) usually parametrize the effect of gravity waves on the global circulation. These parametrizations are very simplified. For this reason, comparisons 5 with global observations of gravity waves are needed for an improvement of parametrizations and an alleviation of model biases.We present a gravity wave climatology based on atmospheric infrared limb emissions observed by satellite (GRACILE).GRACILE is a global data set of gravity wave distributions observed in the stratosphere and the mesosphere by the infrared limb sounding satellite instruments High Resolution Dynamics Limb Sounder (HIRDLS) and Sounding of the Atmosphere 10 using Broadband Emission Radiometry (SABER). Typical distributions (zonal averages and global maps) of gravity wave vertical wavelengths and along-track horizontal wavenumbers are provided, as well as gravity wave temperature variances, potential energies and absolute momentum fluxes. This global data set captures the typical seasonal variations of these parameters, as well as their spatial variations. The GRACILE data set is suitable for scientific studies, and it can serve for comparison with other instruments (ground based, airborne, or other satellite instruments) and for comparison with gravity wave distri-15 butions, both resolved and parametrized, in GCMs and CCMs.

“…The temperature values are retrieved from SABER measurements of the atmospheric 15 μm CO2 limb emission. Utilized here are the SABER 1.07 data, which has good temperature accuracy with error in the order of ±1.4 K in lower stratosphere, ±1 K in middle stratosphere and ±2 K in upper stratosphere and lower mesosphere (e.g., Remsberg et al, 2008).…”

We investigate the role of convective processes in triggering middle atmospheric gravity waves with the help of simultaneous measurements of middle atmospheric temperature variability from two tropical stations, Gadanki (13.5 o N, 79.2 o E) and Arecibo (18.3 o N, 66.7 o W). Our data reveal that some of the wave periods are similar at both locations indicating the source regions of waves to be similar at both the stations. However, the potential energies of short period gravity waves are found to be significantly higher over Gadanki compared to that at Arecibo. The most striking observation is that background wind conditions were similar and convective processes occurred very close to Gadanki compared to Arecibo. In the view absence of other wave sources during the period of observations, we suggest the strength as well as the distance of convective cells from the location of the observations is responsible for the observed differences in gravity wave spectrum and energies.
