An Adaptive Dealiasing Method Based on Variational Analysis for Radar Radial Velocities Scanned with Small Nyquist Velocities
(American Meteorological Society, 2012)revious velocity?azimuth display (VAD)-based methods of dealiasing folded radial velocities have relied heavily on the VAD uniform-wind assumption and, thus, can fail when the uniform-wind assumption becomes poor around ... -
Modification and Tests of Particle Probe Tips to Mitigate Effects of Ice Shattering
(American Meteorological Society, 2012)ce particle shattering may significantly contaminate measurements taken by airborne particle probes in ice clouds. Environment Canada and the NASA Glenn Research Center (GRC) undertook efforts to modify and test probe tips ... -
Geostationary Enhanced Temporal Interpolation for CERES Flux Products

Removing Spurious Low-Frequency Variability in Drifter Velocities
(American Meteorological Society, 2012)atellite-tracked drifting buoys of the Global Drifter Program have drogues, centered at 15-m depth, to minimize direct wind forcing and Stokes drift. Drogue presence has historically been determined from submergence or ... -
Long-Term Evaluation of Temperature Profiles Measured by an Operational Raman Lidar
(American Meteorological Society, 2013)his study investigates the accuracy and calibration stability of temperature profiles derived from an operational Raman lidar over a 2-yr period from 1 January 2009 to 31 December 2010. The lidar, which uses the rotational ... -
Estimating Oceanic Turbulence Dissipation from Seismic Images
(American Meteorological Society, 2013)eismic images of oceanic thermohaline finestructure record vertical displacements from internal waves and turbulence over large sections at unprecedented horizontal resolution. Where reflections follow isopycnals, their ... -
Quality Control of Accumulated Fields by Applying Spatial and Temporal Constraints
(American Meteorological Society, 2012)ccumulating gridded fields over time greatly magnifies the impact of impulse noise in the individual grids. A quality control method that takes advantage of spatial and temporal coherence can reduce the impact of such noise ... -
Salinity Transport in the Florida Straits
