Improved resolution backscatter measurements with the SeaWinds pencil-beam scatterometer
The SeaWinds scatterometer was launched on the NASA QuikSCAT spacecraft in June 1999 and is planned for the Japanese ADEOS-II mission in 2000. In addition to generating a global Ku-band backscatter data set useful for a variety of climate studies, these flights will provide ocean-surface wind estimates for use in operational weather forecasting. SeaWinds employs a compact “pencil-beam” design r...
متن کاملHigh Resolution Surface Backscatter Measurements with the Sea Winds Pencil - Beam
To continue and expand upon the foundation provided by the recent flight of the NASA Scatterometer (NSCAT), NASA is developing the SeaWinds instrument which is scheduled to fly on the Quikscat mission in November 1998, and on the Second Japanese Earth Observation Satellite (ADEOS-11) to be launched in early 2000. In a significant design departure from previous “fan-beam” scatterometer systems, ...
متن کاملHigh-resolution measurements with a spaceborne pencil-beam scatterometer using combined range/Doppler discrimination techniques
Conically scanning pencil-beam scatterometer systems, such as the recently launched SeaWinds radar, constitute an important class of instruments for spaceborne climate observation. In addition to ocean winds, scatterometer data are being applied to a wide range of land and cryospheric applications. A key issue for future scatterometer missions is improved spatial resolution. Pencil-beam scatter...
متن کاملTradeoffs in the design of a spaceborne scanning pencil beam scatterometer: application to SeaWinds
SeaWinds is a spaceborne wind scatterometer to be flown on the second Japanese Advanced Earth Observing Satellite (ADEOS-II) in 1999. An important international element of NASA’s earth observing system (EOS), SeaWinds is an advanced follow-on to the NASA scatterometer (NSCAT) on the first ADEOS platform. Unlike previous operational spaceborne scatterometer systems, SeaWinds employs a scanning “...
متن کاملCorrecting SeaWinds Scatterometer Measurements for Atmospheric Attenuation
An attenuation-correction algorithm for the SeaWinds instrument uses the AMSR brightness temperature to find the attenuation experienced by the scatterometer signal. The algorithm uses the concept of excess temperature TeXto evaluate the attenuation. The excess temperature TeXis the difference between the measured brightness temperature and the temperature of the emitting surface. ~e algorithm ...
