Estimations of the effect of modern ozone absorption cros-ssections data on calculation of the atmospheric transmission and fluxes, measured using Sun photometers in the UV spectral region, are made. The ozone absorption cross-sections, often used in radiative codes, and new data of Serdyuchenko et al. are considered.
This paper presents study results of the technical features of Cr2+:ZnSe laser, which performs differential absorption LIDAR measurements for atmospheric constituents and pollutants. Simulation of atmospheric optical depth was carried out using HITRAN2012 for a Cr2+:ZnSe laser spectral wavelength tunability range on the line-by-line basis. The best wavelengths pairs of λON and λOFF and suitable gases to be detected in DIAL measurements of several molecular species were chosen.
Our research into generation of a set of absorption cross sections of atmospheric molecules is reviewed briefly. Particular emphasis is placed on a description of a software toolkit for building information objects that characterize molecules and weakly bound molecular complexes, an application that provides the import and export of the absorption cross sections and representation of metadata and ontolology of information resources collected in a set.
