OVERALL IT WAS GOOD INFORMATION

Was a good module in 2004 - but now really needs to be updated!

• Describe the process of active remote sensing • State the wavelengths used for deriving ocean surface wind speed and direction • State the main variables that are used in the model function for deriving wind vectors (speed and direction) • Define azimuth angle as it relates to satellite remote sensing geometry • Define the incidence angle as it relates to satellite remote sensing geometry • State the atmospheric conditions when wind vectors may be compromised • Compare the scan strategies of fan beam and conical scatterometers • Explain why certain parts of a conical scatterometer swath may have compromised accuracy

July 2014: The theory and technological description of ocean wind speed detection with scatterometers is still valid. The lesson however does not cover the products and operational implementation of the current generation scatterometers including Metop ASCAT, Oceasat OSCAT, and HY-2 SCAT.
