An investigation of wave-induced momentum flux through phase averaging of open ocean wind and wave fields
… investigation of the influence of the dominant, wind-driven, surface waves on the vertical flux of horizontal momentum in the marine surface layer over open ocean conditions. Through a procedure which involves phase averaging the wind fields at the period of the dominant waves, the wave-induced …

Calibration of and Attitude Error Estimation for a Spaceborne Scatterometer using Measurements Over Land
… to measure radar backscatter over the world's oceans. These measurements are used to generate estimates of ocean wind speed and direction. Scatterometers must be calibrated before their measurements are scientifically useful. However, the calibration of NSCAT must be done in orbit. A new …

Hurricane Wind Retrieval Algorithm Development For An Airborne Conical Scanning Scatterometer
Reliable ocean wind vector measurements can be obtained using active microwave remote sensing (scatterometry) techniques. With the increase in the number of severe hurricanes making landfall in the United States, there is increased emphasis on operational monitoring of hurricane winds from …

A Roughness Correction for Aquarius Ocean Brightness Temperature Using the CONAE MicroWave Radiometer
… (SSS), using an L-band radiometer that measures ocean brightness temperature (Tb). The application of L-band radiometry to retrieve SSS is a difficult task, and therefore, precise Tb corrections are necessary to obtain accurate measurements. One of the major error sources is the effect of ocean …

Wind stress over the open ocean
… cruises of the RRS Discovery in the Southern Ocean to obtain a large data set of open-ocean wind stress estimates. The wind speed varied from near-calm to 26 m/s, and the sea-air temperature differences ranged from -8 to +4°C. It is shown that, under unstable atmospheric conditions, the …

An Ocean Surface Wind Vector Model Function For A Spaceborne Microwave Radiometer And Its Application
Ocean surface wind vectors over the ocean present vital information for scientists and forecasters in their attempt to understand the Earth's global weather and climate. As the demand for global wind velocity information has increased, the number of satellite missions that carry wind-measuring …

Atmosphere-vegetation interactions over South Africa
… feeding in over the interior from the SE Indian Ocean. Wind speed changes over the adjacent ocean were also evident, and are probably related to the changes in the South Atlantic and Indian high pressures. A southwards extension of the Hadley Cell was also suggested, as well as changes in …

High Resolution Wind Retrieval for SeaWinds on QuikSCAT
… developed that enables improved the resolution wind estimates from SeaWinds data. This thesis presents the development of three key portions of the high resolution wind retrieval algorithm: Compositing individual σ-0 measurements and Kp, Retrieved wind bias correction, and ambiguity selection …

Towards Improved Estimates of Upper Ocean Energetics
… energy exchanged between the atmosphere and the ocean is an important parameter in understanding the Earth’s climate. One way of quantifying this energy exchange is through the use of “wind work,” or the work done on the ocean by the wind. Since wind work is calculated according to the …
