The fact that life on the earth's surface depends upon a rather small amount of ozone in the stratosphere has been known for some time. This ozone layer filters harmful ultraviolet radiation from reaching the earth and life as we know it has developed within these restraints. It is only recently, however, that scientists have understood that the amount of ozone in the stratosphere is controlled by trace amounts of substances other than ozone. These substances can be roughly broken down into families, the nitrogen, oxygen, chlorine, hydrogen and sulfur families. The concern is as to whether human activities can add significantly to the natural trace substances in the stratosphere and affect the balance of ozone.","PeriodicalId":199214,"journal":{"name":"Topical Meeting on Spectroscopy in Support of Atmospheric Measurements","volume":"83 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":"116682609","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}

High Resolution Photoelectric VUV Cross Section Measurements of Atmospheric Molecules 大气分子的高分辨率光电VUV截面测量

Parkinson","doi":"10.1364/sam.1980.wp24","DOIUrl":"https://doi.org/10.1364/sam.1980.wp24","url":null,"abstract":"Accurate cross sections of the Schumann-Runge (S-R) bands of O2 are needed to determine the opacity of the atmosphere to solar radiation that causes the dissociation of stratospheric constituents such as NO. In particular, the principal photodissociation processes for NO occur in the δ(0,0) and δ(1,0) bands near 191 and 183 nm, respectively; the former is in the range of the S-R (5,0) band, and the latter is in the range of the S-R (9,0) and (10,0) bands. Detailed cross section measurements that resolve the rotational structure of these bands are necessary for the calculation of predissociation rates. However, the determination of accurate cross sections is straight-forward only if the instrumental band width is small compared with the line width being measured. The true cross section of rotationally discrete lines may vary significantly over the instrumental band width, and this can lead to seriously underestimated peak cross sections and distorted line profiles. The two experimental conditions required for cross section measurements of high accuracy for such molecules are the attainment of the highest possible spectroscopic resolution and the use of photoelectric rather than photographic detection.","PeriodicalId":199214,"journal":{"name":"Topical Meeting on Spectroscopy in Support of Atmospheric Measurements","volume":"175 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":"122928661","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}

A careful examination of the curve of growth for typical stratospheric absorption lines indicates that for limb-viewing experiments, the long geometric paths through the atmosphere may result in higher sensitivity to collision broadening, relative to that of nadir-viewing experiments. Unfortunately, efforts in laboratory spectroscopy have usually been concentrated on obtaining line positions, strengths, and assignments, while the more difficult halfwidth measurements have been made very infrequently. In this paper, we present the results of halfwidth-sensitivity studies for ozone retrievals from typical limb-viewing absorption or emission experiments using both high-resolution spectroscopy and broad-band radiometric techniques.","PeriodicalId":199214,"journal":{"name":"Topical Meeting on Spectroscopy in Support of Atmospheric Measurements","volume":"21 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":"124128886","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}

Current models predict mixing ratios for CℓO peaking at a value < 1:109 near 35 km altitude (1), and model profiles give an integrated column density towards the zenith of < 2.5 × 1014 cm-2, making radiometric detection of emission lines extremely difficult through the intervening atmosphere. Heretofore, experimental detection has relied on balloon-born in-situ measurements (2) or on attempts at remote mm-wave (3) or IR detection (4) from high-flying aircraft or balloon platforms. We have developed and successfully used a ground-based mm-wave spectrometer employing some novel features to detect the J = 11/2 → 9/2 rotational transition of CℓO in emission at 204.352 GHz.
