    • Power Ratio Estimation in Incoherent Backscatter Lidar: Heterodyne Receiver with Square Law Detection 

      Rye, B. J. (American Meteorological Society, 1983)
      Comparative return irradiance estimation in a two channel heterodyne lidar receiver should be facilitated by processing finite data samples obtained in a period short compared with that of atmospheric fluctuations affecting ...

    • Attenuation Correction in Dual-Wavelength Analyses 

      Tuttle, John D.; Rinehart, Ronald E. (American Meteorological Society, 1983)
      In using a dual-wavelength radar system to detect hail, erroneous positive hail signals can result because of the stronger attenuation of the shorter wavelength radar beam. We present a simple technique to correct for ...

      Shaw, Roger H.; Tavangar, Jahangir; Ward, David P. (American Meteorological Society, 1983)
      The u, w velocity covariance above and within a plant canopy (Zea mays L) was examined using the technique of quadrant analysis to separate the momentum transport into events classified as sweep, ejection, and outward and ...

    • Integral Scales for the Nocturnal Boundary Layer. Part II: Heat Budget, Transport and Energy Implications 

      Stull, Roland B. (American Meteorological Society, 1983)
      In Part I, external forcings such as pressure gradient, terrain roughness and imposed cooling were used to forecast the thickness and strength of an exponentially-shaped (ES) nocturnal boundary layer (NBL) temperature ...

    • Improvements in the Accuracy of Operational Satellite Soundings 

      McMillin, L. M.; Gray, D. G.; Drahos, H. F.; Chalfant, M. W.; Novak, C. S. (American Meteorological Society, 1983)
      Root-mean-square differences between satellite and radiosondes for the past three years that TIROS-N has been operational are examined. They show a pronounced annual cycle because the statistics are dominated by the Northern ...

    • A Sensitive Fast-Response Manometric Wind Sensor 

      Kunkel, K. E.; Bruce, C. W. (American Meteorological Society, 1983)
      A manometric type of wind sensor has been developed. This sensor convert the dynamic pressure of the wind into a modulated dynamic pressure signal which can then be sensed using microphones. This permits wind speed ...

    • Downward Longwave Radiation at the Surface from Satellite Measurements 

      Darnell, Wayne L.; Gupta, Shashi K.; Staylor, W. Frank (American Meteorological Society, 1983)
      A new technique is presented for generating downward longwave flux at the Earth's surface from satellite meteorological data and a radiative transfer model The technique was tested by using TIROS-N data from 41 passes over ...

    • Contact Versus Immersion Freezing of Freely Suspended Droplets by Bacterial Ice Nuclei 

      Levin, Zev; Yankofsky, Saul A. (American Meteorological Society, 1983)
      Droplets freely suspended in the air stream of a wind tunnel were nucleated with dedicated bacterial cells in either the contact or immersion mode. Immersion freezing seemed to give a noncontinuous frequency distribution ...

    • Reorientation of Hydrometeors in Aircraft Accelerated Flow 

      Beard, K. V. (American Meteorological Society, 1983)
      The drag force, instantaneous canting angle and response characteristics are discussed for large hydrometeors in horizontally accelerated airflow. Comparisons of calculated canting angles are made with data from an aircraft ...

    • The Effect of Bias in Divisional and State Mean Temperatures on Weather-Crop Yield Model Predictions: A Case Study in Indiana 

      Dale, R. F.; Nelson, W. M. L.; McGarrahan, J. P. (American Meteorological Society, 1983)
      Historical series of mean temperatures for climatological divisions and the state of Indiana contain systematic biases, the greatest being about ?1.0°C in the Central Division in the 1940s. When these data are used in ...

    • Crop–Climate Modeling Using Spatial Patterns of Yield and Climate. Part 1: Background and an Example from Australia 

      Wigley, T. M. L.; Qipu, Tu (American Meteorological Society, 1983)
      A new technique in statistical crop-climate analysis, the direct linking of spatial patterns of crop yield and spatial patterns of climate, is explored. Yield and climate data from networks of crop reporting districts and ...

    • Supercooled Liquid Water and Ice Crystal Distributions Within Sierra Nevada Winter Storms 

      Heggli, Mark F.; Vardiman, Larry; Stewart, Ronald E.; Huggins, Arlen (American Meteorological Society, 1983)
      Cloud physics data measured by aircraft during two successive winter field seasons (1978?79 and 1979?80) of the Sierra Cooperative Pilot Project operating over the Sierra Nevada Range have been examined in order to determine ...
