An Intercalibration of METEOSAT-1 and GOES-2 Visible and Infrared Measurements
(American Meteorological Society, 1984)An intercomparison between radiative parameters determined from visible and infrared channels of the METEOSAT-1 and GOES-2 geosynchronous satellites has been carried out using data obtained over the central Atlantic Ocean ... -
Observations of Tropospheric Temperature Fluctuations with the MU Radar-RASS
(American Meteorological Society, 1994)Applying the RASS (radio acoustic sounding system) technique to the MU (middle and upper atmosphere) radar, profiles of both temperature and wind velocity were observed every 90 s in the height range of about 1.5?7.0 km, ... -
Improved Radio Acoustic Sounding Techniques
(American Meteorological Society, 1994)Improved radio acoustic sounding system (RASS) technology for use with radar wind profilers has been developed and applied to 915-MHz and 50-MHz profilers. The most important advance is the simultaneous measurement of the ... -
An Unfolding Algorithm for Profiler Winds
(American Meteorological Society, 1994)The National Oceanic and Atmospheric Administration has completed the installation of a 30-site demonstration network of wind-profiling radars in the central United States. The network is being used to demonstrate and ... -
The Christmas Island Wind Profiler: A Prototype VHF Wind-Profiling Radar for the Tropics
(American Meteorological Society, 1994)After a decade of development, VHF wind profilers are being used for atmospheric research at several locations in the tropical Pacific. A prototype 50-MHz wind profiler was installed on Christmas Island in 1985 and has ... -
Case Studies of the Vertical Velocity Seen by the Flatland Radar Compared with Indirectly Computed Values
(American Meteorological Society, 1994)The hypothesis that temporal averages of vertical motions over a single radar station are representative of weather systems large enough to be resolved by the radiosonde network is tested using data from the Flatland VHF ... -
Measurement of Synoptic-Scale Vertical Velocities by Two Nearby VHF Doppler Radars in Very Flat Terrain
(American Meteorological Society, 1994)An experimental field campaign to measure synoptic-scale vertical velocities was conducted from 5 to 11 January 1991 in the Urbana-Champaign, Illinois, region, which is in very flat terrain far from mountains. Both the ... -
Tropospheric Profiling—Matching Research and Operational Needs with Emerging Technologies
(American Meteorological Society, 1994) -
Correction of Marine Air Temperature Observations for Solar Radiation Effects
(American Meteorological Society, 1993)The effect of incoming solar radiation on merchant ships' observations of air temperature was assessed as part of the Voluntary Observing Ships' Special Observing Project for the North Atlantic (VSOP-NA), The ships' reports ... -
Evaluation of the Sparton Tight-Tolerance AXBT
(American Meteorological Society, 1993)Forty-six near-simultaneous pairs of conductivity-temperature-depth (CTD) and Sparton ?tight tolerance? air expendable bathythermograph (AXBT) temperature profiles were obtained in summer 1991 from a location in the Sargasso ... -
A Random Wave Method for Detecting Phase Imbalance in a Coherent Radar Receiver
(American Meteorological Society, 1993)The question of monitoring the angle between the in-phase (I) and quadrature (Q) channels of a coherent radar receiver is considered in this paper. Random interference-type scattering (e.g., rain echo) is assumed so that ... -
Evaluation of a Bowen Ratio Measurement System over Forest and Clear-Cut Sites at Petawawa, Ontario
(American Meteorological Society, 1984)This paper reports on the features of a reversing measurement system for the determination of the Bowen ratio. Ten-junction thermopiles are used to measure wet- and dry-bulb temperature differences, and a single thermocouple ... -
Wind Fields at the Sea Surface Determined from Combined Ship and Satellite Altimeter Data
(American Meteorological Society, 1993)A data processing method based on a kriging technique was developed to merge two data sources relative to wind velocity at the sea surface within a basin-scale region (the tropical Atlantic Ocean): one from in situ wind ... -
Tidal Current Predictions Using Rotary Empirical Orthogonal Functions
(American Meteorological Society, 1993)In the conventional point tidal analysis approach, a set of tidal harmonic constituents is derived from each time series of currents. These sets of tidal constituents are then used to predict the tidal currents. For a large ... -
A Critical Review of the Database Acquired for the Long-Term Surveillance of the Middle Atmosphere by the French Rayleigh Lidars
(American Meteorological Society, 1993)The database obtained by Rayleigh lidars over the south of France is now used for monitoring the middle-atmosphere structure and to validate satellite data. For these reasons it is crucial to ensure the quality of the data. ... -
Comparison of an Experimental NOAA AVHRR Cloud Dataset with Other Observed and Forecast Cloud Datasets
(American Meteorological Society, 1993)CLAVR [cloud from AVHRR (Advanced Very High Resolution Radiometer)] is a global cloud dataset under development at NOAA/NESDIS (National Environmental Satellite, Data, and Information Service). Total cloud amount from two ... -
Stability of the Earth Radiation Budget Experiment Scanner Results for the First Two Years of Multiple-Satellite Operation
