While the number of observations from space and stratospheric balloons is still small there is already a large number of ground based instruments measuring ozone and a variety of important trace gases. Most of the ground based instruments work in solar occultation (transmittance measurement) within the Network for Detection of Stratospheric Change whereas instruments measuring thermal emission of radiation are rare. For source photon noise limited observation the sensitivity of an emission measurement is better if the optical band width is larger than about 1-10 cm-1. Furthermore, emission measurements have a larger versatility since they are independent from the time of day.","PeriodicalId":221045,"journal":{"name":"Fourier Transform Spectroscopy","volume":"98 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":"134211805","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}

In atmospheric spectroscopy the measured spectrum is usually not analyzed simultaneously as a whole, but microwindows which are dedicated to certain target species are used for the inversion process. An optimum microwindow contains prominent transitions of the target species, leading to high sensitivities of the measured spectral signal to the target parameters, while the signal of transitions of non-target species shall be low. In the early days of atmospheric spectroscopy microwindows were defined and selected by experienced spectroscopists. Nowadays there is a growing need to define and select optimized microwindows in an objective and reproduceable manner.","PeriodicalId":221045,"journal":{"name":"Fourier Transform Spectroscopy","volume":"4 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":"134252821","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}

It is becoming popular also for time-resolved measurements with step-scan interferometers providing for the widest range of possible time constants and repetition rates. The simpler, more numerous continuously scanning interferometers have seemed less suitable for time-resolved measurements because such data acquisition needs to be more or less closely synchronized to the continuous stream of sampling requests issued by these instruments. Of the several schemes for TRS with continuous-scan instruments, the interleaved or stroboscopic technique least restricts the time constant and repetition rate of the transient events, but this method is prone to artifacts and noise [1,2,3]. Small variations of the interferometer-mirror speed are a source of noise and possibly artifacts [3,4], Our “Event-Locked” data acquisition / analysis method eliminates these problems by reducing the need to synchronize the data acquisition to the scanning motion of the mirror, which simultaneously simplifies the experiment [5].","PeriodicalId":221045,"journal":{"name":"Fourier Transform Spectroscopy","volume":"8 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":"131089200","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}
