Scientific paper

An important goal of the NASA TIMED satellite mission is to map the temperature field of earth's upper atmosphere (core region 60-180 km) on a global scale. The SABER instrument onboard TIMED uses measurements of the CO2 limb emissions at 15 microns to derive height profiles of atmospheric temperatures (altitude 40-135 km) with a vertical resolution of 2 km. As part of a novel program to investigate the dynamics of mesospheric temperature variability at low latitudes, ground-based measurements using the USU-CEDAR Mesospheric Temperature Mapper (MTM) located at Maui, Hawaii (20.8N, 156W) have recently been compared with TIMED/SABER overpasses within 500 km of the Hawaiian islands. The combination of these two separate measurement techniques provides a powerful and complimentary method for investigating temporal and spatial induced variability. This poster focuses on data from February and July/August 2002 to investigate winter-summer differences and nocturnal variability.
