The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) experiment was launched onboard the TIMED satellite at 7:07:35 am PST on December 7, 2001 from the Western Test Range. The satellite was placed in a 74.1o inclined, 625 km orbit by a Delta II rocket. 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 selected spectral bands ranging from 1.27 mm to 17 mm wavelength. The observed limb emission profiles are being processed on the ground to provide vertical profiles with 2 km altitude resolution the following: temperature, O3, H2O, and CO2 mixing ratios; volume emission rates due to O2 (1D), OH (u=3,4,5), OH (u=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 54oS to 87oN with alternating hemisphere coverage every 60 days. SABER measurements taken just after activation include data on the cold summer mesopause in the southern hemisphere and observations of the dynamically active northern hemisphere winter. This paper provides an experiment overview, orbital performance, example data products, and preliminary comparisons with correlative observations. Science implications of the data will be discussed.
