Abstract
The purpose of this article is to summarize the attempts made to carry out spectrum reconstruction for interferograms obtained from the Tropospheric Emission Spectrometer (TES) on-board the Aura satellite, after the laser used to trigger the sampling unit malfunctioned in the spring of 2016. In particular, we highlight the drawbacks that made reconstruction problematic and the approaches attempted to overcome them. These drawbacks include ill-conditioning of the reconstruction problem incurred with nonuniformly spaced interferogram samples, discrepancies in the reported and true spatial locations of the samples, and low resolution of the spatial location data. Algorithms used to overcome these pitfalls, involving regularized reconstruction methods in the case of unknown/imperfect sample locations, are presented, along with reconstruction results showing the difficulties associated with the spectrum reconstruction problem.
