Specific observables of interest are water vapor, trace gases, aerosol size and density, wind, and temperature. The goal is to study atmospheric processes continuously for extended periods in remote field locations. This laboratory has just reached field ready status with sensors for aerosol and trace gas measurement based on established techniques. A development program is underway to enhance the sensor suite with several new techniques and instruments that are expected to significantly extend the state of the art in remote trace gas analysis. The new sensors will be incorporated into the lab during the next two years.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127149190","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 resulting high-resolution infrared solar absorption spectra from these observations have so far been analyzed for the vertical profiles of several species (O3, HNO3, ClNO3, HCl, HF, N2O, CH4 and H2O) of immediate importance as correlative measurements for other satellite instruments, such as those carried on the Upper Atmospheric Research Satellite. Results for these gases together with those of other species measured by ATMOS, such as the more abundant man-made chlorofluorocarbons (CFC-11, CFC-12, HCFC-22) are compared with similar measurements made by this instrument from data acquired during its first flight in April, 1985. In the period between these two flights, the halogenated gases are expected to have increased measurably in concentration due to the continued release of the halogenated source gases. These ATMOS data provide a simultaneous measurement of the increase in the tropospheric source gases as well as the halogen sink species, HCl and HF.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"174 48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133722413","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 change in cloudiness small enough to be undetectable by satellites can have a large impact on global climate. It is therefore very important to accurately measure the meteorological parameters associated with cloud formation. These parameters include water vapor, cloud condensation nuclei (CCN), and vertical lofting of air to colder altitudes. For boundary layer clouds, the vertical velocities associated with lofting need only be a few centimeters per second. The vertical velocity can be induced by topographical features and/or surface heat flux. We will describe an experiment that used optical techniques to quantify surface heat flux changes related to boundary layer cloud formation and cloud shadowing effects and relate these changes to convergence associated with vertical velocities over a dry prairie grassland. The major result of this experiment showed that optical turbulence at different scales provides heat and momentum flux changes associated with cloud effects on a time scale fast enough to resolve cloud formation and movement. Standard tower measurements, because they are not spatially averaged, require tens of minutes for valid comparable estimates.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123905283","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}

While few ground based observing systems provide the high resolution coverage with sufficient areal extent necessary to study mesoscale variation, satellite observing systems have proven to be extremely useful in this endeavor. For instance, moisture and stability products from the geostationary platform VISSR Atmospheric Sounder (VAS) exhibit interesting detail at the meso B (20-200 km) level (Chesters et al., 1986; Smith et al., 1985). However, variation at the meso C scale (2-20 km) and at the lower end of the meso B scale ( about 20-100 km) suffer from the effects of noise. Noise can be greatly reduced by using a high resolution data collection system. The Multispectral Atmospheric Mapping Sensor (MAMS), with its 100m resolution over a 36km swath, is well suited to provide high resolution mesoscale information about the atmosphere and surface of the earth. A more complete depiction of the atmospheric state at the smaller scales is possible through the combination of the high horizontal resolution MAMS data with the vertical sounding data of the VAS.","PeriodicalId":320202,"journal":{"name":"Optical Remote Sensing of the Atmosphere","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132170346","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}
