NDSD-1000: High-resolution, high-temperature Nitrogen Dioxide Spectroscopic Databank

We present a high-resolution, high-temperature version of the Nitrogen Dioxide Spectroscopic Databank called NDSD-1000. The databank contains the line parameters (positions, intensities, self- and air-broadening coefficients, exponents of the temperature dependence of self- and air-broadening coefficients) of the principal isotopologue of NO₂. The reference temperature for line intensity is 296 K and the intensity cutoff is 10⁻²⁵ cm⁻¹/molecule cm⁻² at 1000 K. The broadening parameters are presented for two reference temperatures 296 K and 1000 K. The databank has 1,046,808 entries, covers five spectral regions in the 466–4776 cm⁻¹ spectral range and is designed for temperatures up to 1000 K. The databank is based on the global modeling of the line positions and intensities performed within the framework of the method of effective operators. The parameters of the effective Hamiltonian and the effective dipole moment operator have been fitted to the observed values of the line positions and intensities collected from the literature. The broadening coefficients as well as the temperature exponents are calculated using the semi-empirical approach. The databank is useful for studying high-temperature radiative properties of NO₂. NDSD-1000 is freely accessible via the internet site of V.E. Zuev Institute of Atmospheric Optics SB RAS (ftp://ftp.iao.ru/pub/NDSD/). - Highlights: • NDSD-1000 is a high-temperature infrared spectroscopic NO₂ databank. • NDSD-1000 contains calculated line parameters for the 466–4776 cm^–1 spectral range. • NDSD-1000 can be used for temperatures up to 1500 K. • NDSD-1000 is freely accessible at (ftp.iao.ru/pub/NDSD/).
