The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) experiment was launched onboard the TIMED satellite by a Delta II rocket at 7:07:35 am PST on December 7, 2001 from the Western Test Range. The satellite was placed in a 74.1 degree inclined, 625 km orbit. The primary science goal of SABER is to achieve major advances in understanding the structure, energetics, chemistry, and dynamics in the atmospheric region extending from 60 to 180 km altitude. This will be accomplished using the space flight proven experiment approach of spectral broadband limb emission radiometry. The SABER instrument scans the earth limb in 10 spectral bands ranging from 1.27 (m to 17 (m wavelength. The observed limb emission profiles are being processed on the ground to provide vertical profiles with 2 km altitude resolution of the following parameters: temperature, O3, H2O, and CO2 mixing ratios; volume emission rates due to O2 (singlet delta), OH (v=3,4,5), OH (v=7,8,9), and NO; key atmospheric cooling rates, solar heating rates, chemical heating rates, and airglow losses; atomic oxygen, atomic hydrogen and geostrophic winds. Measurements are made both night and day over the latitude range from 52 S to 83 N with alternating hemispheric coverage every 60 days. This paper provides a brief description of the TIMED mission, its science goals and selected results. The SABER experiment will be discussed in more detail including its orbital performance, example data products, and comparisons with correlative observations. Response of the atmosphere to a large solar storm observed by SABER will be described.
