The Accuracies of Smoothed Sea Surface Height Fields Constructed from Tandem Satellite Altimeter Datasets
(American Meteorological Society, 2003)A technique previously developed for assessing the effects of sampling errors on sea surface height (SSH) fields constructed from satellite altimeter data is extended to include measurement errors, thus providing estimates ... -
Cloud Liquid Water and Ice Content Retrieval by Multiwavelength Radar
(American Meteorological Society, 2003)Cloud liquid water and ice content retrieval in precipitating clouds by the differential attenuation method using a dual-wavelength radar, as a function of the wavelength pair, is first discussed. In the presence of ... -
Optimal Planning of a Weather Radar Network
(American Meteorological Society, 2003)An approach to the optimal planning of a weather radar network is presented. In the approach, several aspects affecting the planning decision, including terrain blockage, the need to measure with two Doppler weather radars ... -
Rapid Daytime Estimation of Cloud Properties over a Large Area from Radiance Distributions
(American Meteorological Society, 2003)An algorithm is developed to rapidly estimate cloud properties for a large area from daytime imager data. In this context, a large area refers to a grid cell composed of many imager pixels. The algorithm assumes a gamma ... -
On the Temperature Correction of the Aquatrak Acoustic Tide Gauge
(American Meteorological Society, 2003)Temperature corrections for the Aquatrak acoustic tide gauge are derived. These account for variable temperature (and hence sound velocity) along the sounding tube, thermal expansion of the calibration tube, and the thermal ... -

Air Flow and Particle Trajectories around Aircraft Fuselages. IV: Orientation of Ice Crystals
(American Meteorological Society, 1986)The equations of motion for an ice crystal moving around a body are simplified and used to obtain the preferred angular orientation of the crystals with respect to the body. It is shown that the calculated orientation ... -

Lagrangian Velocity Distributions in a High-Resolution Numerical Simulation of the North Atlantic
(American Meteorological Society, 2003)The statistical properties of Lagrangian velocities in a high-resolution numerical simulation of the North Atlantic Ocean are analyzed and discussed in the framework of particle dispersion parameterizations. Consistent ... -
The Accuracies of Crossover and Parallel-Track Estimates of Geostrophic Velocity from TOPEX/Poseidon and Jason Altimeter Data
(American Meteorological Society, 2003)Mean-squared errors of surface geostrophic velocity estimates from the crossover and parallel-track methods are calculated for altimeters in the Ocean Topography Experiment (TOPEX)/Poseidon and Jason orbits. As part of the ... -
Strategies for Circulation Evaluation of Aircraft Wake Vortices Measured by Lidar
(American Meteorological Society, 2003)An assessment of different methods for circulation evaluation from lidar measurement data of aircraft wake vortices is performed. The surface integral of vorticity serves as baseline case that is compared to a method that ... -
A Variable Sky-View Platform for the Measurement of Ultraviolet Radiation
(American Meteorological Society, 2003)One of the more difficult tasks confronting atmospheric researchers today is the acquisition of long-term radiometric measurements that encapsulate variability in the sky hemisphere as well as time. High quality spatial ... -
Preliminary Steps in Assimilating SSM/I Brightness Temperatures in a Hurricane Prediction Scheme
(American Meteorological Society, 2003)Different aspects of assimilating satellite-observed microwave radiances (brightness temperatures) into the initial vortex of a hurricane prediction model are discussed. The tangent linear and adjoint observation operators ... -
Intercomparison of NDSC Ground-Based Solar FTIR Measurements of Atmospheric Gases at Lauder, New Zealand
(American Meteorological Society, 2003)A formal intercomparison of atmospheric total column measurements of N2O, N2, CH4, O3, HCl, HNO3, and HF by two ground-based solar Fourier transform infrared (FTIR) spectrometers conducted as part of the Network for the ... -
Spurious Signals in TRMM/VIRS Reflectance Channels and Their Effect on Aerosol Retrievals
(American Meteorological Society, 2003)Aerosol optical depths, τ1 and τ2, and the Ångström exponent α = ?ln(τ1/τ2)/ln(?1/?2), are retrieved from daytime measurements (sun zenith angle ?o < 60°) over ocean in reflectance bands 1 (?1 = 0.63 µm) and 2 (?2 = 1.61 ... -
The Shape–Slope Relation in Observed Gamma Raindrop Size Distributions: Statistical Error or Useful Information?
(American Meteorological Society, 2003)The three-parameter gamma distribution n(D) = N0Dµ exp(??D) is often used to characterize a raindrop size distribution (DSD). The parameters µ and ? correspond to the shape and slope of the DSD. If µ and ? are related to ... -
Finding Boundary Layer Top: Application of a Wavelet Covariance Transform to Lidar Backscatter Profiles
(American Meteorological Society, 2003)Several recent studies have utilized a Haar wavelet covariance transform to provide automated detection of the boundary layer top from lidar backscatter profiles by locating the maximum in the covariance profiles. This ... -
Accuracy of Wind Fields Observed by a Bistatic Doppler Radar Network
