AB: The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument aboard the TIMED (Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) satellite has been obtaining measurements since January 2002. The Version 1.02 Level 2A LTE temperature data have been compared with temperature data obtained by other satellites, lidars, and falling spheres. The agreement between the SABER temperature profiles and those for other data sets indicates that the Version 1.02 SABER LTE temperature versus pressure distributions should be suitable for use in dynamical studies of the middle atmosphere through the calculation of winds and potential vorticity. A first step in the calculation of dynamical parameters is to use a sequential estimation technique to obtain synoptic temperature distributions from the asynoptic SABER satellite data. The algorithm that was used generates Fourier coefficients of temperature (through zonal wavenumber 6) which are output at noon UT for each day as a function of latitude. From these spectral coefficients, synoptic temperature fields are estimated. Geopotential height fields are calculated from the mapped temperature data, and winds are obtained using the geopotential height fields. The estimated data are compared with products from the Met. Office analyses to further assess the quality of the SABER data.
