AB: Singular Value Decomposition (SVD) analysis is both a powerful diagnostic tool and an effective method of noise filtering. We present the results of an SVD analysis of an ensemble (~ 500) of spectral residuals (observed - calculated) acquired in September 2004 from a 16-orbit (26 hours) Aura Tropospheric Emission Spectrometer (TES) Global Survey and compare them to alternative methods such as zonal averages. In particular, the technique highlights issues such as the orbital variation of instrument response and incompletely modeled effects of surface emissivity and atmospheric composition. Thus it becomes a driver for improving calibration and retrieval algorithms.
