We present in this paper some of the results obtained in our laboratory in the fundamental bands of CO, CO2, N2O, CH4, CH3D, C2H2, and NH3 at temperatures and other conditions relevant to various planetary atmospheres. A critical comparison with other published work, including some well-known spectroscopic databases, and some revealing trends as to the variation of the spectral line parameters with temperature are presented.","PeriodicalId":221045,"journal":{"name":"Fourier Transform Spectroscopy","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125823097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The future European polar satellite system, METOP, is scheduled to carry an interferometer to obtain infrared spectra. The Japanese satellite ADEOS (Advanced Earth Observing Satellite) launched on August 16, 1996 is also carrying an interferometer capable of measuring infrared spectra. These future infrared measurements will all possess spectral resolutions of better than 1 cm-1 and have quasi-continuous spectral coverage in the 3 μm ~ 15 μm region. With nearly thousands of spectra measurements at any single field of view, it is important to develop an innovative retrieval algorithm which cannot only handle a large volume of measurements but can also yield high precision sounding profiles.","PeriodicalId":221045,"journal":{"name":"Fourier Transform Spectroscopy","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128878310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the advent of bidimensional array detectors the throughput advantage of a Fourier-transform spectrometer (FTS) can be exploited to create this type of instrument. The coupling of the FTS of the CFH Telescope, which is a step-scan interferometer, to a near-infrared camera has been realised. With this combination, spectro-imaging in any bandpass between 1 and 2.5 μm is possible within a circular 24” field of view, at seeing-limited spatial resolution. Spectral resolution in any spectral domain within these limits, up to 30,000 is choosable. Illustrations are given by the study of several typical objects.","PeriodicalId":221045,"journal":{"name":"Fourier Transform Spectroscopy","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132085641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
