SAGE III has been selected for the definition phase study (phase A/B) for the National Polar Platform One (NPOP1) and the Space Station Attached Pay load (SSAP) of the Environmental Observatory System (Eos) Mission in the late 1990’s. The SAGE III instrument follows a long heritage of successful flight missions such as the SAM II, SAGE I, and SAGE II missions in producing global data sets of stratospheric aerosol, ozone, nitrogen dioxide, and water vapor. One of the unique characteristics of the SAGE III instrument is the ability to provide measurements of oxygen A-band absorption at the 760 nm spectral region. Oxygen A-band absorption measurements will provide independent pressure and temperature data for the retrieval of other constituents as measured by the SAGE III instrument.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"20 S2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132390252","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}

Our work with these devices has shown that the output pass band of the filter has a full width at half maximum (FWHM) on the order of 10Å, while theoretically one would expect it to be on the order of 1Å for a collimated beam. We have conducted a computer simulation study of the transmission characteristics of these filters and have found that a divergent beam will have a broader transmission curve than a nondivergent beam, and have determined the tolerance for divergence to produce an acceptably narrow pass band. We have found that a higher-order transverse mode pattern can produce a complicated transmission profile. We have also studied the effect of misalignment of individual stages in the filter to determine the tolerances in alignment of the stages. The temperature stability required to maintain the transmission peak wavelength of the filter within an allowable range has been obtained.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"1 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":"129967500","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 VMR profile retrieval is based on an iterative inversion algorithm, which utilizes a multilayer line-by-line calculations. In total, 96 ozone vertical profiles were retrieved from 48 infrared spectra by using two O3 absorption lines near 10 micron spectral region. These profiles were compared with 21 ozonesonde measurements from nearby ozone sounding stations. The two micro-window regions used for O3 profile retrievals are 1146 cm-1 and 1163 cm-1 spectral regions. Averaged discrepancies were less than ±15 % above 8 km for 1146 cm-1 retrievals, while those were less than ±11 % between 16 and 36 km for 1163 cm-1 retrievals. The standard deviation (SD) of averaged discrepancies were less than ±17 % between 16 and 36 km for 1146 cm-1 retrievals, while those were less than ±12 % between 16 and 36 km for 1163 cm-1 retrievals.

Because micro-scale structures can be identified by their water content, the technique offers new opportunities to visualize and study the phenomena. There are applications to many practical problems in agricultural and water management as well as at waste storage sites. Conventional point sensors are limited and are inappropriate for use in complex terrain or varied vegetation and cannot be extrapolated over even modest ranges. To this end, techniques must be developed to measure the variables associated with evapotranspirative processes over large areas and varied surface conditions. A scanning water-Raman Lidar is an ideal tool for this task in that it can measure the water vapor concentration rapidly with high spatial resolution without influencing the measurements by the presence of the sensor. The solar-blind water-Raman Lidar used in this experiment is based upon the technique pioneered by Cooney1. Operational parameters of the Lidar are described in Table 1.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"54 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":"134312853","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}
