    Solitons and ionospheric modification (1982)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: The possibility of Langmuir soliton formation and collapse during ionospheric modification is investigated. Parameters characterizing former facilities, existing facilities, and planned facilities are considered, using a combination of analytical and numerical techniques. At a spatial location corresponding to the exact classical reflection point of the modifier wave, the Langmuir wave evolution is found to be dominated by modulational instability followed by soliton formation and three-dimensional collapse. The earth's magnetic field is found to affect the shape of the collapsing soliton. These results provide an alternative explanation for some recent observations.

    Solitons and ionospheric heating (1982)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: It is noted that for parameters characterizing the Platteville ionospheric heating facility, the Langmuir wave evolution at the exact reflection point of the heater wave involves an oscillating two-stream instability followed by a collisionally damped three-dimensional soliton collapse. The result gives an alternative explanation for certain experimental observations.

    Airborne brightness temperature measurements of the polar winter troposphere as part of the Airborne Arctic Stratosphere Experiment 2 and the effect of brightness temperature variations on the diabatic heating in the lower stratosphere (1993)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: In this paper we report radiometric measurements of tropospheric brightness temperatures obtained during the AASE 2 experiment. These measurements represent the first attempt to characterize effective radiative temperatures as seen from above the troposphere during the Arctic winter. The reported measurements include brightness temperatures at 6.7 and 10.5 microns as seen from the NASA DC-8 aircraft flying at about 11 km altitude. We also present radiative transfer calculations to estimate the effect of tropospheric brightness temperature on the lower stratospheric heating rates. Because of the recent massive eruption of the Pinatubo volcano, we also discuss the effects of a volcanic aerosol layer. It is concluded that small particles like the volcanic aerosol or polar stratospheric clouds (PSCs) type 1 do not affect stratospheric heating rates by much; on the other hand, larger particles, PSCs types 2 and 3, may have significant effects on heating rates and consequently on dynamics of the lower stratosphere. The dynamical effects of local stratospheric temperature variations are briefly discussed.

    Latitudinal survey of spectral optical depths of the Pinatubo volcanic cloud - Derived particle sizes, columnar mass loadings, and effects on planetary albedo (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: Airborne measurements are examined of spectral optical depths, radiative fluxes, and scattered radiation fields during the NASA Caribbean mission (July 7-14, 1991) to characterize the Pinatubo volcanic cloud. The latitudinal and spectral dependence are reported of the volcanic cloud's optical depth. From these measurements moments of the particle-size distribution are determined. The change in planetary albedo induced by the volcanic cloud is calculated for the range of measured optical depths with the objective of assessing the impact on the solar radiation budget. Mid-visible optical depths higher than 0.4 were observed, placing the Pinatubo stratospheric cloud among the thickest ever measured. The latitudinal distribution of extinction shows that by July 7, 1991 the volcanic cloud had extended to 30 deg N. The effective particle radius was determined to be between 0.18 and 0.35 micron with a corresponding columnar mass loading between 35 and 80 mag/sq m.

    The Moho as a magnetic boundary revisited (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: Approximately 400 globally distributed xenolith samples are examined to determine whether continental regions are characterized by relatively magnetic crusts lying on relatively nonmagnetic mantles. Samples of mantle peridotites and mafic granulites by Wasilewski et al. (1979) are supplemented by samples of mantle and crustal xenoliths from Asia, North America, Africa, and Antarctica. The data indicate that a magnetic crustal layer overlies a nonmagnetic mantle much in the same manner as proposed by Jarchow and Thompson (1989). Nonmagnetic chrome spinels and magnesian ilmenites make up the ultramafic upper-mantle xenolith suite. Mafic rocks are the typically magnetic components of the crust, and induced magnetizations can account for long-wavelength magnetic anomalies measured remotely by aircraft and spacecraft.

    Ozone and aircraft operations (1981)
    In:  CASI
    Details
    Publication Date: 2006-02-14
    Description: The cabin ozone problem is discussed. Cabin ozone in terms of health effects, the characteristics of ozone encounters by aircraft, a brief history of studies to define the problem, corrective actions taken, and possible future courses of action are examined. It is suggested that such actions include avoiding high ozone concentrations by applying ozone forecasting in flight planning procedures.

    Prediction limits for foF2 (1979)
    In:  CASI
    Details
    Publication Date: 2006-01-16
    Description: Some of the factors limiting the prediction of foF2 are investigated using median and hourly foF2 values recorded at stations in the Australian ionosonde network. Different time and spatial scales together with different levels of solar and geomagnetic activity are considered. All data used in the analysis are displayed in a series of scatter diagrams which provide an overall view of the accuracy limits for foF2 predictions.
