Lidar-Observed Stress Vectors and Veer in the Atmospheric Boundary Layer
(American Meteorological Society, 2013)his study demonstrates that a pulsed wind lidar is a reliable instrument for measuring angles between horizontal vectors of significance in the atmospheric boundary layer. Three different angles are considered: the wind ... -
Fixed-Antenna Pointing-Angle Calibration of Airborne Doppler Cloud Radar
(American Meteorological Society, 2013)oppler velocity measurements from airborne meteorological Doppler radars require removal of the aircraft motion contribution in order to provide radial velocity of hydrometeor targets. This is a critical step for hydrometeor ... -
Performance of Hot Plate for Measuring Solid Precipitation in Complex Terrain during the 2010 Vancouver Winter Olympics

High-Resolution Topography-Following Chemical Mapping of Ocean Hypoxia by Use of an Autonomous Underwater Vehicle: The Santa Monica Basin Example
(American Meteorological Society, 2013)his paper reports on the execution of a combined chemical sensing/high-resolution terrain-following autonomous underwater vehicle (AUV) survey to explore the fine structure and functional boundaries of the Santa Monica ... -
Aspects of the Correlation between Sodar and Mast Instrument Winds
(American Meteorological Society, 2013)n a uniform terrain site, differences between a sodar and a mast-mounted cup anemometer will arise because of turbulent fluctuations and wind components being measured in different spaces, and because of the inherent ... -
