Absorption cross-sections of atmospheric constituents: NO2, O-2, and H2O

Absorption spectroscopy, which is widely used for concentration measurement s of tropospheric and stratospheric compounds, requires precise values of t he absorption cross-sections of the measured species. NO2, O-2 and its coll ision-induced absorption spectrum, and H2O absorption cross-sections have b een measured at temperature and pressure conditions prevailing in the Earth 's atmosphere. Corrections to the generally accepted analysis procedures us ed to resolve the convolution problem are also proposed.
