We are extracting altimeter data for each tropical storm where QuikSCAT reprocessed data is available and are using it to study air-sea interactions and to characterize hurricane effects that may be of both scientific and operational use. From the altimeter records we use Ku and C band significant wave height and sigma0 data, skewness data from retracking records, along with radiometer measurements and atmospheric model fields. Where QuikSCAT data are also available they provide measurements of sigma0 as well as wind speed and direction. We are investigating scatterometer and altimeter measurement effects both statistically and by case studies. We want to derive operationally useful methods for improving storm forecasting and assessment. Topics to be investigated include:
If additional data types such as sea surface temperature, ocean heat content, other radiometer data, or model information are available along with the QuikSCAT data, we will also use those in investigating some of these effects.
