A Hail Size Distribution Impact Transducer
A Hail Size Distribution Impact Transducer John E. Lanea, Robert C. Youngquistb, William D. Haskella, and Robert B. Coxa aASRC Aerospace Corporation, P.O. Box 21087, Kennedy Space Center, FL 32815 [email protected] [email protected] [email protected] bNational Aeronautics and Space Administration (NASA), Kennedy Space Center, FL 32899 [email protected] Abstract: An active impact transducer has been designed and tested for the purpose of monitor- ing hail fall in the vicinity of the Space Shuttle launch pads. An important outcome of this design is the opportunity to utilize frequency analysis to discriminate between the audio signal generat- ed from raindrop impacts and that of hailstone impacts. The sound of hail impacting a metal plate is subtly but distinctly different than the sound of rain impacts. This useful characteristic permits application of signal processing algorithms that are inherently more robust than tech- niques relying on amplitude processing alone in the implementation of a hail disdrometer. 1 1. Introduction Impact disdrometers have long been a useful meteorological tool to measure and quantify rainfall drop size distributions, where a drop momentum is converted into a single electrical im- pulse.1,2 The electrical impulse amplitude is converted to an estimate of drop diameter by means of an empirical calibration formula. The calibration may be a one-time procedure involving dropping numerous known-size-calibration drops from a tower of sufficient height to achieve terminal velocity. The test drop sizes must adequately span the size range of interest. Alternative- ly, or as a supplement to the single drop calibration, an in situ method of comparing the sum of accumulated drop impulses to the tip time interval of a tipping-bucket rain gauge may be uti- lized.3 Prior to launch, the Space Shuttle and other NASA launch vehicles are primarily large ther- mos bottles containing substantial quantities of cryogenic fuels. -

TWIXT OCEAN AND PINES: THE SEASIDE RESORT AT VIRGINIA BEACH, 1880-1930 Jonathan Mark Souther Master of Arts University of Richmond, 1996 Robert C. Kenzer, Thesis Director This thesis descnbes the first fifty years of the creation of Virginia Beach as a seaside resort. It demonstrates the importance of railroads in promoting the resort and suggests that Virginia Beach followed a similar developmental pattern to that of other ocean resorts, particularly those ofthe famous New Jersey shore. Virginia Beach, plagued by infrastructure deficiencies and overshadowed by nearby Ocean View, did not stabilize until its promoters shifted their attention from wealthy northerners to Tidewater area residents. After experiencing difficulties exacerbated by the Panic of 1893, the burning of its premier hotel in 1907, and the hesitation bred by the Spanish American War and World War I, Virginia Beach enjoyed robust growth during the 1920s. While Virginia Beach is often perceived as a post- World War II community, this thesis argues that its prewar foundation was critical to its subsequent rise to become the largest city in Virginia. -
East Antarctic Sea Ice in Spring: Spectral Albedo of Snow, Nilas, Frost Flowers and Slush, and Light-Absorbing Impurities in Snow
Annals of Glaciology 56(69) 2015 doi: 10.3189/2015AoG69A574 53 East Antarctic sea ice in spring: spectral albedo of snow, nilas, frost flowers and slush, and light-absorbing impurities in snow Maria C. ZATKO, Stephen G. WARREN Department of Atmospheric Sciences, University of Washington, Seattle, WA, USA E-mail: [email protected] ABSTRACT. Spectral albedos of open water, nilas, nilas with frost flowers, slush, and first-year ice with both thin and thick snow cover were measured in the East Antarctic sea-ice zone during the Sea Ice Physics and Ecosystems eXperiment II (SIPEX II) from September to November 2012, near 658 S, 1208 E. Albedo was measured across the ultraviolet (UV), visible and near-infrared (nIR) wavelengths, augmenting a dataset from prior Antarctic expeditions with spectral coverage extended to longer wavelengths, and with measurement of slush and frost flowers, which had not been encountered on the prior expeditions. At visible and UV wavelengths, the albedo depends on the thickness of snow or ice; in the nIR the albedo is determined by the specific surface area. The growth of frost flowers causes the nilas albedo to increase by 0.2±0.3 in the UV and visible wavelengths. The spectral albedos are integrated over wavelength to obtain broadband albedos for wavelength bands commonly used in climate models. The albedo spectrum for deep snow on first-year sea ice shows no evidence of light- absorbing particulate impurities (LAI), such as black carbon (BC) or organics, which is consistent with the extremely small quantities of LAI found by filtering snow meltwater. -
