TL;DR: The HITRAN compilation consists of several components useful for radiative transfer calculation codes: high-resolution spectroscopic parameters of molecules in the gas phase, absorption cross-sections for molecules with very dense spectral features, aerosol refractive indices, ultraviolet line-by-line parameters and absorptionCross-sections, and associated database management software.
Abstract: This paper describes the status circa 2001, of the HITRAN compilation that comprises the public edition available through 2001. The HITRAN compilation consists of several components useful for radiative transfer calculation codes: high-resolution spectroscopic parameters of molecules in the gas phase, absorption cross-sections for molecules with very dense spectral features, aerosol refractive indices, ultraviolet line-by-line parameters and absorption cross-sections, and associated database management software. The line-by-line portion of the database contains spectroscopic parameters for 38 molecules and their isotopologues and isotopomers suitable for calculating atmospheric transmission and radiance properties. Many more molecular species are presented in the infrared cross-section data than in the previous edition, especially the chlorofluorocarbons and their replacement gases. There is now sufficient representation so that quasi-quantitative simulations can be obtained with the standard radiance codes. In addition to the description and justification of new or modified data that have been incorporated since the last edition of HITRAN (1996), future modifications are indicated for cases considered to have a significant impact on remote-sensing experiments.

TL;DR: In this paper, the authors summarized the cross-sections and indices of refraction on the HIgh-resolution TRANsmission (HITRAN) database and discussed data uncertainties and applications.
Abstract: The cross-sections and indices of refraction on the HIgh-resolution TRANsmission (HITRAN) database are summarized. HITRAN contains a tabulation of cross-sections of atmospheric chemical reservoir and source species, chlorofluorocarbons, hydrochlorofluorocarbons, and hydrofluorocarbons, and indices of refraction of liquid and solid compounds. The temperature and pressure dependences of the cross-sections and the temperature dependence of the indices of refraction are illustrated. Data uncertainties and applications are discussed, and some future needs of the remote-sensing community are identified.

TL;DR: In this paper, multiple wavelength techniques for HALOE and SAGE II data are used to distinguish cirrus from aerosol observations following the eruption of Mount Pinatubo in 1991.
Abstract: [1] Averages of Halogen Occultation Experiment (HALOE) aerosol extinction at 121 hPa for 1993–1999 and Stratospheric Aerosol and Gas Experiment (SAGE II) aerosol extinction between 100 and 140 hPa for 1987–1999 are analyzed in the tropics (20°S–20°N). Multiple wavelength techniques for HALOE and SAGE II data are used to distinguish cirrus from aerosol observations following the eruption of Mount Pinatubo in 1991. SAGE II and HALOE cirrus extinction values are 34 and 28% less, respectively, in 1993 than in 1995–1999, while aerosol extinction decreases over the same time period. SAGE II and HALOE decreases in the frequency of occurrence of cirrus in 1993 are qualitatively similar to the SAGE II decreases in the frequency of occurrence of cirrus, discussed by Wang et al. [1995], after the eruption of El Chichon. Tropopause temperature anomalies in 1993 most likely do not account for the decrease in cirrus observed in 1993 by both the HALOE and SAGE II experiments.

TL;DR: In this article, the relative extinction coefficients for Arctic polar stratospheric clouds (PSCs) were determined using a transmittance-ratio technique from spectral data observed in early 1997 by the Improved Limb Atmospheric Spectrometer (ILAS).
Abstract: [1] The relative extinction coefficients for Arctic polar stratospheric clouds (PSCs) are determined using a transmittance-ratio technique from spectral data observed in early 1997 by the Improved Limb Atmospheric Spectrometer (ILAS). The observed relative extinction coefficients are compared with theoretical coefficients calculated by the Mie theory for single mode lognormal size distributions of PSCs. The observed PSCs are then classified into three types: nitric acid droplets (HNO3/H2O), and nitric acid trihydrate (NAT) solid particles in the form of α-NAT and β-NAT. However, the definitive detection of α-NAT is difficult due to uncertainties of atmospheric temperature measurements and laboratory determination of refractive indices.
