TL;DR: The data and features that have been added or replaced since the previous edition of HITRAN are described, including instances of critical data that are forthcoming.
Abstract: Since its first publication in 1973, the HITRAN molecular spectroscopic database has been recognized as the international standard for providing the necessary fundamental spectroscopic parameters for diverse atmospheric and laboratory transmission and radiance calculations. There have been periodic editions of HITRAN over the past decades as the database has been expanded and improved with respect to the molecular species and spectral range covered, the number of parameters included, and the accuracy of this information. The 1996 edition not only includes the customary line-by-line transition parameters familiar to HITRAN users, but also cross-section data, aerosol indices of refraction, software to filter and manipulate the data, and documentation. This paper describes the data and features that have been added or replaced since the previous edition of HITRAN. We also cite instances of critical data that are forthcoming.

Abstract: Nineteen ninety-eight marks the 25th anniversary of the release of the first HITRAN database. HITRAN is recognized as the international standard of the fundamental spectroscopic parameters for diverse atmospheric and laboratory transmission and radiance calculations. There have been periodic editions of HITRAN over the past decades as the database has been expanded and improved with respect to the molecular species and spectral range covered, the number of parameters included, and the accuracy of this information. The 1996 edition not only includes the customary line-by-line transition parameters familiar to HITRAN users, but also cross-section data, aerosol indices of refraction, software to filter and manipulate the data, and documentation. This paper describes the data and features that have been added or replaced since the previous edition of HITRAN. We also cite instances of critical data that is forthcoming. A new release is planned for 1998.

TL;DR: In this article, the authors present scientific highlights from the first five years of the UARS program, including stratospheric ozone chemistry, the dy-namics of the middle and upper atmosphere, and solar irradiance variations, and discuss the significant impact that UARS observations have had on their under standing of each issue.
Abstract: We present scientific highlights from the Upper Atmosphere Research Satellite (UARS) pro- gram obtained during the first 5 years of the program. The UARS measures the chemical composition and meteorological state of the middle and upper atmo- sphere as well as the solar irradiance. The comprehen- sive suite of UARS geophysical parameters, their near- global coverage, and the multiyear time span have yielded new insights into the processes affecting our atmosphere. In this article we select seven scientific issues, including stratospheric ozone chemistry, the dy- namics of the middle and upper atmosphere, and solar irradiance variations, and discuss the significant impact that the UARS observations have had on our under- standing of each issue.

TL;DR: In this paper, the authors used particle size distributions, measured by the forward scattering spectrometer probe (FSSP 300), to specify polynomial expressions by which polar stratospheric cloud (PSC) extinction data can be converted into volume and area density values for type I, liquid phase PSCs.
Abstract: Particle size distributions, measured by the forward scattering spectrometer probe (FSSP 300), are used in Mie calculations to specify polynomial expressions by which polar stratospheric cloud (PSC) extinction data can be converted into volume and area density values for type I, liquid phase PSCs The calculations are carried out at the wavelengths observed by experiments on the Upper Atmosphere Research Satellite (UARS) and at the stratospheric aerosol measurement (SAM II), stratospheric aerosol and gas experiment (SAGE II), and polar ozone and aerosol measurement (POAM II) wavelength of 1 μm The calculations use laboratory indices that approximate values for ternary solution and sulfuric acid droplets Validation calculations intercompare the SAM II and FSSP 300 area densities, and SAM II and cryogenic limb array etalon spectrometer (CLAES) area densities
