    • Usefulness of Liquid-Water Potential Temperature in a Shallow-Cloud Model 

      Deardorff, J. W. (American Meteorological Society, 1976)
      The advantages of using Betts' (1973) liquid-water potential temperature (?l) and also a total moisture variable (qw) within a shallow-cloud numerical model are enumerated. The saturation condition is parameterized as a ...

    • The Combined Effect of Temperature and Humidity Fluctuations on Refractive Index 

      Wesely, Marvin L. (American Meteorological Society, 1976)
      Depending on whether the radiation under consideration is acoustic, visible or microwave, either temperature or humidity fluctuations are ordinarily assumed to be an insignificant source of refractive index fluctuations. ...

    • Wind Estimates from Cloud Motions: Phase 1 of an in situ Aircraft Verification Experiment 

      Hasler, A. F.; Shenk, W.; Skillman, W. (American Meteorological Society, 1976)
      An initial experiment has been conducted to verify geostationary-satellite-derived cloud motion wind estimates with in situ aircraft wind velocity measurements. The experiment was conducted during December 1972 over the ...

    • Remote Wind Sensing by Acoustic Radar 

      Balser, M.; McNary, C. A.; Nagy, A. E.; Loveland, R.; Dickson, D. (American Meteorological Society, 1976)
      Acoustic radar offers a promising new technique for remotely measuring vector wind velocity. Engineered antenna systems have been constructed that effectively reject noise interference, and the corresponding detection logic ...

    • Infrared Radiative Transfer in Polluted Atmospheres 

      Ackerman, Thomas P.; Liou, Kuo-Nan; Leovy, Conway B. (American Meteorological Society, 1976)
      A four-stream, multi-layered radiative transfer model has been developed to treat the problem of the transfer of infrared radiation in an atmosphere containing both scatterers and absorbers. Each atmospheric layer is ...

    • Low-Level Stability and Pollutant-Trapping Potential for a Rural Area 

      Takle, E. S.; Shaw, R. H.; Vaughan, H. C. (American Meteorological Society, 1976)
      Temperature and wind speed measurements over a 6-year period from a 32 m tower located in a primarily rural area are used to assess the pollutant-dispersive characteristics of a rural site. A monthly comparison of a crude ...

    • Determining Emittances for Use in Infrared Thermometry: A Simple Technique for Expanding the Utility of Existing Methods 

      Idso, Sherwood B.; Jackson, Ray D.; Reginato, Robert J. (American Meteorological Society, 1976)
      A simple laboratory technique is described for making rapid emittance measurements with an infrared thermometer. It is shown that when the infrared thermometer head is held flush against a surface, its output is a linear ...

    • Statistical Objective Analysis of Dual-Doppler Radar Data from a Tornadic Storm 

      Heymsfield, Gerald M. (American Meteorological Society, 1976)
      The horizontal wind and reflectivity fields in a tornadic storm are investigated with dual-Doppler radar. Emphasis is placed on a statistical objective analysis technique of the Eddy-Gandin type for determining these fields ...

    • A Parameterization for the Absorption of Solar Radiation by Water Vapor in the Earth's Atmosphere 

      Wang, Wei-Chyung (American Meteorological Society, 1976)
      A parameterization for the absorption of solar radiation as a function of the amount of water vapor in the earth's atmosphere is obtained. Absorption computations are based on the Goody band model and the near-infrared ...

    • A Global Reference Atmospheric Model for Surface to Orbital Altitudes 

      Justus, C. G.; Roper, R. G.; Woodrum, Arthur; Smith, O. E. (American Meteorological Society, 1976)
      An empirical atmospheric model has been developed which generates values for pressure, density, temperature and winds from surface levels to orbital altitudes. The output parameters consist of components for: 1) latitude, ...

    • Observation of Severe Weather Activities by Doppler Sounder Array 

      Smith, R. E.; Hung, R. J. (American Meteorological Society, 1975)
      A three-dimensional, nine-element, high-frequency cw Doppler sounder array has been used to detect ionospheric disturbances during periods of severe weather, particularly during periods with severe thunderstorms and ...

    • Comments on “The Effect of Tropospheric Temperature Lapse Rates on the Ascent Rates of Pilot Balloons” 

      Nelson, Roger A. (American Meteorological Society, 1975)

    • A Note on the Diurnal, Latitudinal and Seasonal Variation of the Surface Reflection Coefficient 

      Arnfield, A. J. (American Meteorological Society, 1975)
      The diurnal variation of the surface reflection coefficient is quantified using an exponential function of solar zenith angle. The coefficients of this relationship reveal the effects of surface roughness, cloud cover, and ...

    • An Upper Bound Estimate on the Resonance Cross Section for Water Vapor at 694.38 nm 

      Schotland, Richard M. (American Meteorological Society, 1975)
      An experimental study using lidar has been made of possible resonance scattering from water vapor at 694.38 nm. This radiation was not detectable. An upper bound for the differential backscatter resonance cross section, ...

    • Observations of Two Stratospheric Dust Events 

      Shaw, Glenn E. (American Meteorological Society, 1975)
      Two recent volcanic eruptions (Volcan del Fuego in Guatemala, October 1974, and Ngauruhoe in New Zealand, 19 February 1975) may have populated the stratosphere with sufficient ash to create large-scale stratospheric dust ...
