A correlation study of wind speed as measured by the Special Sensor Microwave Imager and the Geosat Altimeter.
correlationstudy00lill.pdf (5.369Mb)Abstract
Wind speed data is routinely acquired at the FLEET NUMERICAL
OCEANOGRAPHIC CENTER (FNOC) in near real time from the SPECIAL SENSOR
MICROWAVE/IMAGER (SSM/I), on board the DEFENSE METEOROLOGICAL
SATELLITE PROGRAM (DMSP) satellite and the RADAR ALTIMETER on board the
GEOSAT satellite. A correlation study is made of the SSM/I and ALTIMETER wind
speed data using five data sets from areas where the DMSP satellite had crossed within
1.1 hours of the GEOSAT satellite. Regions of ocean where the atmosphere was free
of cloud water and precipitation have a high correlation of approximately 0.995, while
areas with precipitation and cloud water have very poor correlation. Areas of high
water vapor content do not appear to adversely affect the high correlation between the
SSM/I and ALTIMETER measured wind speeds.
