Kansas Participation in Sea Winds Instrument Activities

Project Award Date: 09-15-1995


This research continues work on the development of algorithms to correct the SeaWinds data for atmospheric attenuation. This work began originally in connection with the EOS Stikscat program.

SeaWinds is a scanning scatterometer that will fly on a Japanese spacecraft (ADEOS-II), which is also be equipped with an AMSR scanning multifrequency radiometer. Both instruments scan in conical patterns with complete coverage of the ocean surface.

The signal to the SeaWinds will be attenuated when it passes through rain and dense clouds. Since the wind measurement by the SeaWinds will depend on accurate measurements of the scattering from the ocean, the attenuation can cause significant errors in wind measurement. In cloudy and rainy regions, the radiometer signal increases in response to the attenuation. Therefore, the radiometer signal can be used to estimate the attenuation, and the estimate used to correct the signal received by the scatterometer.

Moreover, the radar will receive signals scattered from raindrops. We must estimate this signal to subtract it from the attenuated surface signal. To do so we can use the attenuation estimated from AMSR but must know the rain height to do so. For this purpose we are developing a climatology of rain height using data from the TRMM (Tropical Rain Measuring Mission) satellite.

Combining effects of attenuation and rain scatter will allow us to correct the signals from the surface.

Partner with ITTC

The Information and Telecommunication Technology Center at the University of Kansas has developed several assistance policies that enhance interactions between the Center and local, Kansas, or national companies. 

ITTC assistance includes initial free consulting (normally one to five hours). If additional support is needed, ITTC will offer one of the following approaches: 

Sponsored Research Agreement

Individuals and organizations can enter into agreements with KUCR/ITTC and provide funds for sponsored research to be performed at ITTC with the assistance of faculty, staff and students.

Licensing and Royalty/Equity Agreement

An ITTC goal is the development of investment-grade technologies for transfer to, and marketing by, local, Kansas, and national businesses. To enhance this process, the Center has developed flexible policies that allow for licensing, royalty, and equity arrangements to meet both the needs of ITTC and the company.

Commercialization Development

Companies with a technology need that can be satisfied with ITTC's resources can look to us for assistance. We can develop a relationship with interested partners that will provide for the development of a technology suited for commercialization.

ITTC Resource Access

ITTC resources, including computers and software systems, may be made available to Kansas companies in accordance with the Center's mission and applicable Regents and University policies.
