TL;DR: The new HITRAN is greatly extended in terms of accuracy, spectral coverage, additional absorption phenomena, added line-shape formalisms, and validity, and molecules, isotopologues, and perturbing gases have been added that address the issues of atmospheres beyond the Earth.
Journal ArticleDOI
Water vapor column abundance retrievals during FIFE
TL;DR: In this article, a modified Langley plot algorithm is applied to the retrieval of atmospheric water column abundance from a filtered sunphotometer, which is used to report local column water vapor during the First ISLSCP Field Experiment (FIFE), and comparisons are made with abundances retrieved via FIFE radiosonde observations.
Journal ArticleDOI
Atmospheric Trace Molecule Spectroscopy (ATMOS) Experiment Version 3 data retrievals

TL;DR: Version 3 of the Atmospheric Trace Molecule Spectroscopy (ATMOS) experiment data set for some 30 trace and minor gas profiles is available and results for stratospheric water are more consistent across the ATMOS spectral filters and do not indicate a net consumption of H2 in the upper stratosphere.
Journal ArticleDOI
CFC-11, CFC-12 and HCFC-22 ground-based remote sensing FTIR measurements at Réunion Island and comparisons with MIPAS/ENVISAT data
Minqiang Zhou,Minqiang Zhou,Corinne Vigouroux,Bavo Langerock,Pucai Wang,Geoff S. Dutton,Christian Hermans,Nicolas Kumps,Jean-Marc Metzger,Geoff Toon,Martine De Mazière +10 more
TL;DR: In this article, Fourier transform infrared (FTIR) solar absorption measurements above the Saint-Denis (St Denis) and Maido sites at Reunion Island (21°S, 55°E) with low vertical resolution are discussed.
Journal ArticleDOI
Impact of mesospheric intrusions on ozone-tracer relations in the stratospheric polar vortex

TL;DR: In this article, the impact of mesospheric air on chemical ozone loss in the polar vortex has been studied using ILAS-II satellite measurements. And the results show that ozone mixing ratios ranging between 3.6 and 5.6 ppm are significantly higher than those found in the early vortex reference relation employed to deduce chemical ozone depletion.
