Abstract

A supercontinuum absorption spectroscopy (SAS) approach for measurement of atmospheric constituents is extended to offer increased capability of detecting concentrations of gaseous species. An atmospheric path length greater than 600 m is utilized in the multi-wavelength differential absorption setup. A multi-wavelength algorithm for analysis of the spectra measurements obtained from the return of the supercontinuum source is used to determine the concentrations of species, with comparison to MODTRAN™ 5 simulation spectra. Further developments to the SAS approach and measurements are presented.
