An Extended Comparison between LOWTRAN7 Computed and Observed Broadband Thermal Irradiances: Global Extreme and Intermediate Surface Conditions
(American Meteorological Society, 1993)Differences between observed and LOWTRAN7-computed downward longwave irradiances were examined at each of four globally diverse locations for an entire year at each site. The final results are restricted to times determined ... -
Normalization and Calibration of Geostationary Satellite Radiances for the international Satellite Cloud Climatology Project
(American Meteorological Society, 1993)Procedures are described for normalizing the radiometric calibration of image radiances obtained from the suite of geostationary weather satellites that contributed data to the international Satellite Cloud Climatology ... -
In Situ Observations of Cirrus Cloud Microphysical Properties Using the Counterflow Virtual Impactor
(American Meteorological Society, 1993)This study presents a new technique for making in situ measurements of cirrus cloud microphysical properties. Sampling of cirrus clouds was performed using a counterflow virtual impactor (CVI). The CVI was used to sample ... -
Application Of Microholography for Ground-based In Situ Measurements in Stratus Cloud Layers: A Case Study
(American Meteorological Society, 1993)A holographic droplet and aerosol recording system (HODAR) has been designed and operated in situ in a low-level stratus cloud layer adopting the Fraunhofer in-line technique to measure sizes and velocity vectors of cloud ... -
Proposal for a Spaceborne Dual-Beam Rain Radar with Doppler Capability
(American Meteorological Society, 1993)The potential characteristics and performances of a spaceborne dual-beam radar (or stereo radar) operating at 24 GHz, and devoted primarily to the retrieval of rain-rate structure by using the stereo-radar analysis, were ... -
An 11-cm Coherent Polarimetric Radar for Meteorological Research
(American Meteorological Society, 1993)The Geophysics Directorate of the U.S. Air Force developed a unique 11-cm (S-band) coherent polarimetric radar. The radar can transmit signals of alternating orthogonal polarizations, with either circular or linear basis, ... -
On the Transient Behavior of Conductivity Sensors
(American Meteorological Society, 1984)The response characteristics of a family of conductivity cells typical of those employed in profiling instruments has been examined from a theoretical standpoint, and the conditions established under which such a cell ... -
The Accuracy of Tide-Gauge Measurements at Subtidal Frequencies
(American Meteorological Society, 1993)The accuracy of subinertial sea level, as measured by tide gauges in the Southern California Bight, is investigated. Sea level differences formed from tide gauges separated by less than 50 km are examined. The observed ... -
Comparison of Maximum–Minimum Resistance and Liquid-in-Glass Thermometer Records
(American Meteorological Society, 1993)The replacement of liquid-in-glass (LIG) thermometers with electronic thermometers in the National Weather Service (NWS) cooperative (co-op) network and concern for homogeneous temporal temperature records prompted this ... -
Vicarious Calibration of the Meteosat Visible Channel
(American Meteorological Society, 1993)Postlaunch calibration of the Meteosat visible (VIS) channel has been performed with Meteosat-1, Meteosat-2, and Meteosat-4. The radiance at the satellite radiometer aperture has been determined by independent means and ... -
Microstructure Profiles of Laser-induced Chlorophyll Fluorescence Spectra: Evaluation of Backscatter and Forward-Scatter Fiber-Optic Sensors
(American Meteorological Society, 1993)The implementation and characterization of backscatter and forward-scatter fiber-optic fluorescence sensors attached to a microstructure profiling instrument are described. By using an optical multichannel array detector ... -
A Reformulation and Implementation of the Bryan-Cox-Semtner Ocean Model on the Connection Machine
(American Meteorological Society, 1993)Certain aspects of the Semtner-Chervin version of the Bryan-Cox-Semtner global ocean model are reformulated for improved efficiency on parallel computer architectures and on the Connection Machine CM-2 in particular. These ... -
A Comparison of In-Cloud Measurements Obtained with Six PMS 2D-C Probes
(American Meteorological Society, 1993)During a preparatory experiment (PREICE) for the field campaign of the International Cirrus Experiment (ICE), six different Particle Measuring Systems (PMS) 2D-C probes belonging to five research organizations were ... -
Differential Absorption Lidar Measurements of Atmospheric Temperature Profiles: Theory and Experiment
(American Meteorological Society, 1993)The method of measuring atmospheric temperature profiles with differential absorption lidar (DIAL), based on the temperature dependence of oxygen absorption lines in the near infrared, is investigated in some detail. ... -
Processing and Interpretation of Coherent Dual-Polarized Radar Measurements
(American Meteorological Society, 1993)Dual-polarized coherent radar measurements are used to estimate the differential propagation phase or ?DP between horizontal and vertical polarization states. The slope of ?DP is an estimate of the specific differential ... -
Correction of Inertial Navigation with Loran C on NOAA's P-3 Aircraft
