Scientific paper

This paper will review the system (both software and hardware) used for operational processing of data taken by SABER (Sounding of the Atmosphere using Broadband Emission Radiometry). The SABER experiment was launched aboard the TIMED satellite December 7, 2001 and began science operations January 8, 2002. SABER data will be used to refine the understanding of dynamical and photo-chemical processes in the mesosphere and lower thermosphere. Code for analyzing SABER measurments must rigorously model non-LTE (Local Thermodynamic Equilibrium) processes. If data inversion is to proceed at speeds matching or exceeding measurment collection, then operational processing demands both fast robust radiative transfer codes and efficient computer architecture. The operational codes developed for SABER are based on the rapid GATS BANDPAK algorithms and validated by results from several independent non-LTE research models. Executing these codes on a Beowulf PC cluster enables operational processing at data collection speeds with rigorous and fully coupled non-LTE models.
