Studies on the Transport of CO and Related Biomass Burning Emissions Using Ground-based Fourier Transform Infrared Spectrometry
This work deals with measurements and analysis of solar absorption spectra of atmospheric trace gases in the infrared spectral region, as recorded by a Fourier transform infrared (FTIR) spectrometer. The aim of this work is to study the transport of biomass burning emissions in the free troposphere,...
