Verification of Remotely Sensed Sea Surface Winds in Hurricanes
(American Meteorological Society, 2003)Surface winds in hurricanes have been estimated remotely using the Stepped-Frequency Microwave Radiometer (SFMR) from the NOAA WP-3D aircraft for the past 15 years. Since the use of the GPS dropwindsonde system in hurricanes ... -
Calibration of Johnson–Williams and PMS ASSP Probes in a Wind Tunnel
(American Meteorological Society, 1986)Wet wind tunnel tests have provided calibrations and intercomparisons of the LAMP's cloud liquid water content probes (three Johnson?Williams sensor heads and one PMS ASSP). The tunnel liquid water content was deduced with ... -
A Study of Diurnal Variation of OLR from the GOES Sounder
(American Meteorological Society, 2003)A multispectral outgoing longwave radiation (OLR) estimation technique is applied to GOES Sounder data to study the diurnal cycle of OLR. OLR data collected from several regional areas over the continental United States ... -
Validation of a Technique for Estimating OLR with the GOES Sounder
(American Meteorological Society, 2003)In order to eventually use the capability of the Geostationary Operational Environmental Satellite (GOES) Sounder to capture the diurnal signal of outgoing longwave radiation (OLR), it is necessary to establish its ... -
Combined Infrared Stereo and Laser Ranging Cloud Measurements from Shuttle Mission STS-85
(American Meteorological Society, 2003)Multiangle remote sensing provides a wealth of information for earth and climate monitoring, such as the ability to measure the height of cloud tops through stereoscopic imaging. Further, as technology advances so do the ... -
Aerosol Measurement in the Australian Outback: Intercomparison of Sun Photometers
(American Meteorological Society, 2003)The low background aerosol loadings prevailing over much of the Australian continent necessitate careful attention to the calibration of sun photometers. The validity of such calibrations can only be assessed objectively ... -
Profiles of Low-Level Stratus Cloud Microphysics Deduced from Ground-Based Measurements
(American Meteorological Society, 2003)The microwave radiometer?derived cloud liquid water path (LWP) and a profile of radar reflectivity are used to derive a profile of cloud liquid water content (LWC). Two methods (M1 and M2) have been developed for inferring ... -
Continuous Observations of Humidity Profiles with the MU Radar–RASS Combined with GPS and Radiosonde Measurements
(American Meteorological Society, 2003)In this paper a radar remote-sensing technique of a humidity profile by Tsuda et al. is improved so as to determine continuous time?height variations of humidity. The volume reflectivity (?) and turbulence energy dissipation ... -
Humidity Gradient Profiles from Wind Profiling Radars Using the NOAA/ETL Advanced Signal Processing System (SPS)
(American Meteorological Society, 2003)An algorithm to compute the magnitude of humidity gradient profiles from the measurements of the zeroth, first, and second moments of wind profiling radar (WPR) Doppler spectra was developed and tested. The algorithm extends ... -

Assessment of the Cycle-to-Cycle Noise Level of the Geosat Follow-On, TOPEX, and Poseidon Altimeters
(American Meteorological Society, 2002)The Geodetic Satellite (Geosat) Follow-On (GFO), Ocean Topography Experiment (TOPEX), and Poseidon altimeter white-noise levels have been evaluated using a technique based on high-pass filtering of 1-Hz sea surface height ... -
Retrieval of Composition and Size Distribution of Stratospheric Aerosols with the SAGE II Satellite Experiment
(American Meteorological Society, 1986)The SAGE II satellite system was launched on 5 October 1984. It has seven radiometric channels and is beginning to provide water vapor, NO2, and O2 concentration profiles and aerosol extinction profiles at a minimum of ... -
Micropulse Lidar Signals: Uncertainty Analysis
(American Meteorological Society, 2002)Elastic backscatter lidars are used to determine the vertical distribution of cloud and aerosol layers. One such lidar is the micropulse lidar (MPL). A recent paper by Campbell et al. described an algorithm used to process ... -
Velocity Mapping Capabilities of Present and Future Altimeter Missions: The Role of High-Frequency Signals
(American Meteorological Society, 2002)A detailed analysis of the velocity field mapping capabilities from existing and future multiple altimeter missions is carried out using the Los Alamos North Atlantic high-resolution model. The velocity mapping errors on ... -
Considerations in the Calculation of Vertical Velocity in Three-Dimensional Circulation Models
(American Meteorological Society, 2002)The vertical velocity, w, in three-dimensional circulation models is typically computed from the three-dimensional continuity equation given the free-surface elevation and depth-varying horizontal velocity. This problem ... -
Evaluation of Wind Vectors Observed by QuikSCAT/SeaWinds Using Ocean Buoy Data
(American Meteorological Society, 2002)Wind vectors observed by the QuikSCAT/SeaWinds satellite mission are validated by comparing with wind and wave data from ocean buoys. Effects of oceanographic and atmospheric environment on scatterometer measurements are ... -
A Two-Parameter Wind Speed Algorithm for Ku-Band Altimeters
(American Meteorological Society, 2002)Globally distributed crossovers of altimeter and scatterometer observations clearly demonstrate that ocean altimeter backscatter correlates with both the near-surface wind speed and the sea state. Satellite data from ... -
An Improved Gaussian Jet Model for Deriving Absolute Geostrophic Velocity from Satellite Altimetry
(American Meteorological Society, 2002)Key aspects of a Gaussian jet model for deriving absolute geostrophic velocity from TOPEX/Poseidon altimeter data are improved. Velocities are obtained by synthesizing Gaussian fits to cross-stream velocity anomaly profiles ... -
An Improved Clutter Filtering and Spectral Moment Estimation Algorithm for Staggered PRT Sequences
(American Meteorological Society, 2002)In the staggered pulse repetition time (PRT) radar, the phase difference between the autocorrelations at lag T1 and T2 is used for velocity estimation. This paper investigates velocity estimates from the autocorrelation ...
