Intercomparison of Aircraft and Surface Buoy Meteorological Data during CODE-1
(American Meteorological Society, 1984)Intercomparisons of meteorological data?wind speed and direction, surface temperature and surface pressure?were obtained for NCAR Queen Air overflights of four buoys during the CODE-1 experiment. The overflights were at a ... -
On the Sea-State Bias of the Geosat Altimeter
(American Meteorological Society, 1991)The sea-state bias in a satellite altimeter's range measurement is caused by the influence of ocean waves on the radar return pulse; it results in an estimate of sea level too low according to some function of the wave ... -
Analysis of Errors Due to Polynomial Adjustment of Altimeter Profiles
(American Meteorological Society, 1991)Among the various sources of error on altimetric sea surface height variability, the orbit error has the largest amplitude. However, since orbit error is mostly at long wavelengths, it can theoretically be distinguished ... -
Microelectronic Thermal Anemometer for the Measurement of Surface Wind
(American Meteorological Society, 1991)The paper describes the development and first prototype results of a microelectronic thermal anemometer without moving parts, for the measurement of velocity and direction of surface wind. The central part of the instrument ... -
Biases of Rain Retrieval Algorithms for Spaceborne Radar Caused by Nonuniformity of Rain
(American Meteorological Society, 1991)The biases of various rain retrieval algorithms for a spaceborne rain radar due to nonuniformity of rain are studied using simple models and an actual time sequence of rainfall rate. A conventional rain retrieval algorithm ... -
Non-Rayleigh Scattering Effect in Rain Observations by an X- and Ka-band Dual-Wavelength Radar
(American Meteorological Society, 1991)The effect of non-Rayleigh scattering appearing in a rain observation experiment using a dual-wavelength rain radar, is investigated. The non-Rayleigh scattering effect causes a small difference between the effective radar ... -
Accurate Airborne Surface Temperature Measurements with Chopper-stabilized Radiometers
(American Meteorological Society, 1991)The accuracy of chopper-stabilized radiometers for the meteorological measurement of surface temperatures was investigated during a series of airborne trails, including tests at high altitude using a pressurized aircraft. ... -
Flow Distortion by an Ellipsoid and Its Application to the Analysis of Atmospheric Measurements
(American Meteorological Society, 1991)A model for the upwind influence of bluff bodies on a flow developed by Wyngaard is extended to include bodies without axial symmetry; i.e., ellipsoids with three unequal axes. The requirements and limits for the application ... -
Reducing Drag and Oscillation of Spheres Used for Buoyancy in Oceanographic Moorings
(American Meteorological Society, 2008)Numerical and laboratory results of the drag characteristics are presented for different configurations of an underwater buoyancy package. It is shown that the drag and oscillation of an underwater sphere can be reduced ... -
Surface Pressure and Wind Stress Effects on Sea Level Change Estimations from TOPEX/Poseidon Satellite Altimetry in the Mediterranean Sea
(American Meteorological Society, 2008)Using the classical inverse barometer (IB) correction and the Modèle d?Onde de Gravité à 2 Dimensions (MOG2D) barotropic model in the Mediterranean Sea during the 1993?2002 period, it is shown that surface pressure and ... -
Wind Tunnel Evaluation of PAM II Pressure Ports
(American Meteorological Society, 1991)The Portable Automated Mesonet II (PAM II) is a network of automated remote weather stations developed by the National Center for Atmospheric Research (NCAR) for measuring wind speed and direction, atmospheric pressure, ... -
Hot-Film Measurements from a Small Buoy: Surface Wind Stress Estimates Using the Inertial Dissipation Method
(American Meteorological Society, 1991)The design and deployment of an experimental meteorological buoy are described. A hot-film anemometer is used for in situ calculations of wind velocity variance spectra. The dissipation method is used to derive surface ... -

Dynamic Response of Single Electrode Conductivity Probes in Slow Flows
(American Meteorological Society, 1984)Four designs of single electrode conductivity probes, three of them new, were tested for response characteristics in conditions simulating laboratory internal wave flows. Two of the new designs were shown to be significantly ... -
The Motion of a Solid Sphere in an Oscillating Flow: An Evaluation of Remotely Sensed Doppler Velocity Estimates in the Sea
(American Meteorological Society, 1991)Several popular techniques employed to remotely sense oceanic velocity fields utilize the Doppler shifts of backscattered radiation (such as sound or light) from suspended particles to estimate fluid velocities. Implicit ... -
Mooring Motion Corrections Revisited
(American Meteorological Society, 1991)Several schemes are offered for the correction of temperature and velocity in the thermocline for mooring motion. They require measurements from at least two instruments spanning the thermocline and assume that the temporal ... -
How to Observe the Gyre to Global-Scale Variability in Satellite Altimetry: Signal Attenuation by Orbit Error Removal
(American Meteorological Society, 1991)It is well known that the orbit error removal procedure in satellite altimetry also attenuates the oceanic signal. With the aim of devising observational strategies for the large-scale oceanic variability and deciphering ... -
