Validation of Point Spread Functions of CERES Radiometers by the Use of Lunar Observations
(American Meteorological Society, 2010)The Clouds and the Earth?s Radiant Energy System (CERES) scanning radiometers have been operating to make raster scans of the moon on a quarterly basis to validate the point response function for the three channels of ... -
A Velocity Dealiasing Technique Using Rapidly Updated Analysis from a Four-Dimensional Variational Doppler Radar Data Assimilation System
(American Meteorological Society, 2010)A Doppler velocity dealiasing algorithm is developed within the storm-scale four-dimensional radar data assimilation system known as the Variational Doppler Radar Analysis System (VDRAS). The innovative aspect of the ... -
Modeling, Error Analysis, and Evaluation of Dual-Polarization Variables Obtained from Simultaneous Horizontal and Vertical Polarization Transmit Radar. Part I: Modeling and Antenna Errors
(American Meteorological Society, 2010)In this two-part paper the biases of polarimetric variables from simultaneous horizontally and vertically transmitted (SHV) data are investigated. Here, in Part I, a radar-scattering model is developed and antenna polarization ... -
Error Determination of a Successive Correction Type Objective Analysis Scheme
(American Meteorological Society, 1984)The Purdue Regional Objective Analysis of the Mesoscale (PROAM) is a successive correction type scheme for the analysis of surface meteorological data. The scheme is subjected to a series of experiments to evaluate its ... -
The Collection Efficiency of a Modified Mohnen Slotted-Rod Cloud-Water Collector in Summer Clouds
(American Meteorological Society, 1992)A modified Mohnen slotted-rod collector was used to collect cloud-water samples in summer clouds over the northeastern United States. Cloud-droplet-size distributions were measured with a forward-scattering spectrometer ... -
A Dual-Frequency Microwave Technique for Measuring Rainwater Content
(American Meteorological Society, 1992)While there are many microwave techniques for estimating the rainfall rate, there are presently few if any for accurately determining the rainwater content (W). This study shows that the dual-frequency (38, 25 GHZ) ... -
Automatic Adjustment of AVHRR Navigation
(American Meteorological Society, 1992)An automatic adjustment method of the Advanced Very High-Resolution Radiometer (AVHRR) images navigation has been developed for operational use at the Centre de Météorologic Spatiale (CMS) in Lannion, France. Selected ... -
An Analysis Technique for Deriving Vector Winds and In-Beam Incidence Angles from Radar Interferometer Measurements
(American Meteorological Society, 1992)We present a method for deriving horizontal velocities, vertical velocities, and in-beam incidence angles from radar interferometer data. All parameters are calculated from the slope and intercept of straight lines fitted ... -
Standard Seawater Comparison of Some Recent Batches
(American Meteorological Society, 1991)The comparison experiment results of the standard seawater (SSW) were presented for batches P90, P100, P104, P106, P108 P111, and P112. This work shows that the SSW batch-to-batch agreement was recently improved. The ... -
A Method for Depth and Temperature Correction of Expendable Probes
(American Meteorological Society, 1991)No Abstract available -
Deep ADCP Velocity Measurements in the Gulf Stream
(American Meteorological Society, 1991)This paper presents observations of the velocity structure from two transects across a Gulf Stream meander near 37°N, 68°W. Data were collected with a vessel-mounted 75-kHz acoustic Doppler current profiler (ADCP) to a ... -
Improved Satellite-based Emergency Alerting System
(American Meteorological Society, 1991)Rapid-onset natural hazards have claimed more than 2.8 million lives worldwide in the past 20 years. This category includes such events as earthquakes, landslides, hurricanes, tornadoes, floods, volcanic eruptions, wildfires, ... -
Estimation of Horizontal Diffusion from Oblique Aerial Photographs of Smoke Clouds
(American Meteorological Society, 1991)A photogrammetric method is described for obtaining estimates of the horizontal diffusion parameter σy from oblique aerial photographs of smoke clouds. The method requires three reference markers on the ground to determine ... -
Three-Dimensional Display of Radar Echoes Using the Technique of Marching Cubes
(American Meteorological Society, 1991)We present three-dimensional (3D) displays of meteorological radar echoes. We made surfaces of precipitating clouds specified by some echo intensity (dBZ) by the marching cubes method, which is a high-resolution 3D surface ... -
Tests of Long-Range Ocean Data Telemetry Using Frequency-Agile HF Packet-switching Protocols
(American Meteorological Society, 1991)Experiences with two prototype telemetry systems developed for potential use with moored or drifting ocean instruments are described. The systems transfer data and commands between remote and base stations using direct ... -
Realistic Uncertainties in Pressure and Temperature Calibration Reference Values
(American Meteorological Society, 1984)Field instruments require calibration against standards that introduce-insignificant errors of their own in the process. This paper discusses a pressure and temperature calibration facility, analyzes the error levels ... -
