AB: Observed upper atmospheric temperatures from the NASA SABER sensor and the NCAR WACCM theoretical model were made within the years 2002 to 2007. These upper atmospheric measurements come from the temperature data set derived using measurements from the CO2 channels aboard the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument. This sensor is part of the NASA Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite which has been operational since January 2002. Five years of data are used to identify global trends from and make comparisons with the Whole Atmosphere Community Climate Model (WACCM). Seasonal comparisons are made for atmospheric pressures between 10 and 10-4 millibars, and over a global range of latitudes and longitudes. These results are used to examine the long term trends of the temperature during a portion of a solar cycle, and help ascertain what factors affect the temperature trends. The F10.7 index will be used to enable correlations to be obtained.
