Abstract

Extending our developments of a previously reported supercontinuum lidar system has increased the capability for measuring long path atmospheric concentrations. The multi-wavelength capability of the supercontinuum laser source has the advantage of obtaining multiple line differential absorption spectra measurements to determine the concentrations of various atmospheric constituents. Simulation software such as MODTRAN 5 has provided the means to compare and evaluate the experimental measurements. Improvements to the nanosecond supercontinuum laser fiber coupled transceiver system have allowed open atmospheric path lengths greater than 800 m. Analysis of supercontinuum absorption spectroscopy and measurements utilizing the updated system are presented.
