The primary science goal of SABER is to achieve fundamental and important advances in understanding of the energetics, chemistry, and dynamics, in the atmospheric region extending from 60 km to 180 km altitude, which has not been comprehensively observed on a global basis. This will be accomplished using the space flight proven experiment approach of broad spectral band limb emission radiometry. SABER will scan the horizon in 12 selected bands ranging from 1.27μm to 17μm wavelength. The observed vertical horizon emission profiles will be mathematically inverted in ground data processing to provide vertical profiles with 2 km vertical resolution, of temperature, O3, H2O, NO, NO2, CO, and CO2. SABER will also observe key emissions needed for energetics studies at 1.27μm [O2(1Δ)], 2μm [OH(υ=7,8,9)], 1.6μm [OH(υ=3,4,5)], 4.3μm [CO2(ν3)], 5.3μm (NO), 9.6 μm (O3), and 15 μm [CO2(ν2)]. These measurements will be used to infer atomic hydrogen and atomic oxygen, the latter inferred three different ways using only SABER observations. Measurements will be made both night and day over the latitude range from the southern to northern polar regions.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125150741","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}

This need is evidenced by the recent creation of the Clean Air Act Amendments (CAAA), of which the Title III-Hazardous Air Pollutants (HAP) amendments mandate the complete revision and expansion of the earlier Clean Air Act (CAA), section 112.1 As was pointed out by Grant, Kagann and McClenny,2 optical remote sensing technologies are expected to play a very important role in insuring that various facilities are in compliance with the Maximum Achievable Control Technology (MACT) standards for the reduction of HAP emissions that are called for in section 301 of Title III. Unfortunately, however, many of these technologies have varying detection and applicability characteristics which often dictate the conditions under which one can use the sensor to detect, identify or monitor a chemical species. Some of the advantages3-8 that a Raman-based pollution sensor possess are: (1) very high selectivity (chemical specific fingerprints), (2) independence from the excitation wavelength (ability to monitor in the solar blind region), (3) chemical mixture fingerprints are the sum of its individual components (no spectral cross-talk), (4) near independence of the Raman fingerprint to its physical state (very similar spectra for gas, liquid, solid and solutions), and (5) insensitivity of the Raman signature to environmental conditions (no quenching, or interference from water). The detection of atmospheric components using Raman backscattering of laser radiation dates back to the pioneering work of Leonard9 in 1967. In that study, he used a pulsed N2 gas laser at 337.1 nm to generate Raman return signals from N2 and O2.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115997143","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 martian atmosphere is primarily CO2 (95%), with strong vertical mixing, cold temperatures (typically 220K), low pressures (6 mb at the surface), high atmospheric dust and cloud particle content, and no man-made atmospheric constituents. Earlier difficulties in explaining why the atmosphere was not more decomposed into CO and O2 have been placated with models using updated reaction rates, 'moderate' eddy mixing of order 107 cm2s-1, and the odd hydrogen catalytic cycle (Shimazaki, 1989; Krasnopolsky, 1992). Odd nitrogen and sulfur catalytic cycles are of marginal importance, and other catalytic cycles shown to be important in the terrestrial atmosphere are unimportant on Mars (Yung et al., 1977; Krasnopolsky, 1992). Currently, much work is being undertaken to examine the importance of heterogeneous chemistry (e.g., Atreya and Blamont, 1990; Krasnopolsky, 1992), but uncertainties in particle properties make efficiencies difficult to evaluate. Also, atmospheric chemistry may significantly alter atmospheric composition on climatic timescales, particularly during periods of low obliquity (Lindner and Jakosky, 1985).","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125614353","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 continuing effort is involved in improving the sensitivity of such measurements, and is exemplified by the literature.[1-10] The Mobile Atmospheric Research Laboratory (MARL) at Lawrence Livermore National Laboratory (LLNL) is currently developing a method to improve the sensitivity of wind sounding in the lower through middle atmosphere using a pair of Fabry-Perot interferometers in parallel. This technique, first described by Chanin, et al.[4], for the middle atmosphere using Doppler Rayleigh lidar, can be applied to the lower atmosphere where Mie (aerosol) backscatter is strong. Elastic events, inherent in both Rayleigh and Mie backscatter, dominate the return signal throughout the atmosphere. Both are susceptible to local wind vectors; which will Doppler shift the laser frequency proportional to the wind velocity. A pair of Fabry-Perot interferometers, tuned to either side of the laser frequency, will provide necessary data to determine the shift in frequency of the backscattered signal. Spectral drift and jitter of the laser and a lack of data points to determine the wind vector place limits on the sensitivity of the system. A method to minimize each of these will be presented.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125844381","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}
