Abstract
Laser Absorption Spectroscopy (LAS) has been used over the last several decades for the measurement of trace gasses in the atmosphere. For over a decade, DOAS measurements from multiple sources and tens of retororeflectors have been combined with sparse-sample tomography methods to estimate the 2D distribution of trace gas concentrations and underlaying fluxes from pointlike sources. In this work, we consider the ability of such a system to detect and estimate the parameters of single point leaks which may arise as a failure mode for carbon dioxide storage. The leak is assumed to be at a constant rate giving rise to a plume which depends on the wind velocity. We demonstrate the ability of our approach to detect leaks using numerical simulation and a preliminary measurement.Citation
