RISThe Polarization Characteristics of Lidar Scattering from Snow and Ice Crystals in the Atmosphere
Publisher: American Meteorological Society
Abstract: The effects of ice crystals on the backscatter polarization in lidar returns have been measured. Scattering from ground-level snow of varying density, high-altitude cirrus clouds and ice pellet shower clouds has been studied ...
Investigation of the Spatial Variability of the Convective Boundary Layer Heights over an Isolated Mountain: Cases from the MATERHORN-2012 Experiment
Publisher: American Meteorological Society
Abstract: patiotemporal variability in the convective boundary layer height zi over complex terrain is governed by numerous factors such as land surface processes, topography, and synoptic conditions. Observational datasets to ...
Lidar-Derived Distribution of Cloud Vertical Location and Extent
Publisher: American Meteorological Society
Abstract: This paper summarizes the results of a statistical analysis of lidar-determined cloud geometrical properties measured during the 1989 and 1991 campaigns of the Experimental Cloud Lidar Pilot Study. Useful lidar descriptors ...
Lidar-Derived Cloud Optical Properties Obtained during the ECLIPS Program
Publisher: American Meteorological Society
Abstract: This paper presents the Statistical properties of lidar-derived values of cloud extinction coefficients σ and optical depths τ. The data were collected at Toronto during two measurement phases (phase 1: September?October ...
Analysis of Feed Errors in Tapping by Contact Stress Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the most common tapping errors, mismatch of tap feed rate and the thread pitch, has a significant effect on the tapping thrust signal and the resultant thread profile. The underfeed ...
Mechanistic Model for Tapping Process With Emphasis on Process Faults and Hole Geometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mechanistic approach for modeling the tapping process is presented. A methodology for computing chip load is developed for an arbitrary tap geometry. The mechanics of cutting for tapping is ...
Overview of the 2018 Workshop on Iterative Errors in Unsteady Flow Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two workshops were held at the ASME V&V Symposiums of 2017 and 2018 dedicated to Iterative Errors in Unsteady Flow Simulations. The focus was on the effect of iterative errors on numerical simulations performed with ...
The Experimental Cloud Lidar Pilot Study (ECLIPS) for Cloud—Radiation Research
Publisher: American Meteorological Society
Abstract: The Experimental Cloud Lidar Pilot Study (ECLIPS) was initiated to obtain statistics on cloud-base height, extinction, optical depth, cloud brokenness, and surface fluxes. Two observational phases have taken place, in ...
The MATERHORN: Unraveling the Intricacies of Mountain Weather
Publisher: American Meteorological Society
Abstract: merging application areas such as air pollution in megacities, wind energy, urban security, and operation of unmanned aerial vehicles have intensified scientific and societal interest in mountain meteorology. To address ...
