Abstract: Dual pulse repetition frequency (PRF) is a commonly used technique, in operational Doppler weather radar networks, that extends the unambiguous Doppler velocity. The technique requires the measurement of the radial velocity ...

Abstract: The Precipitation Occurrence Sensor System (POSS) is a small X-band Doppler radar originally developed by the Meteorological Service of Canada for reporting the occurrence, type, and intensity of precipitation from Automated ...

Abstract: Precipitation detection and typing estimates from four sensors are evaluated using standard operational meteorological observations as a reference. All are active remote sensors radiating into a measurement volume near the ...

Abstract: Three techniques for the measurement of raindrop size distributions are compared using data from a Joss-Waldvogel disdrometer (JWD), a Particle Measuring Systems 2DG spectrometer (PMS), and an Atmospheric Environment Service ...

Abstract: Measured barometric pressure fluctuations in a borehole drilled 600 m into the unsaturated zone at a site on the eastern slope of Yucca Mountain, Nevada, are used to compute pneumatic diffusivities and air permeabilities ...

Abstract: (http://pavementinteractive.org) is an ongoing experiment in coupling a participatory web application with a unique data set to improve transportation engineering knowledge transfer. Specifically, Pavement Interactive is ...

Abstract: Pavement surface condition data play a pivotal role in the analysis and design of pavement rehabilitation strategies. In project design, this information is usually used by a limited number of pavement engineering specialists ...

Abstract: A majority of U.S. and international roads are low volume. Pavements on these roads, which are often owned or managed by local agencies with limited resources, represent a large transportation infrastructure asset and could ...

Abstract: The 2010 Winter Olympic and Paralympic Games took place in Vancouver, British Columbia, Canada, on 12?28 February and 12?21 March 2010, respectively. Weather forecasting presents specific challenges at the various Olympic ...
