Impact of Usage of Multiple-satellite Sensors on Accuracy of Sea Surface Wind Data

摘要

The purpose of this study is to describe time variation of accuracy in daily-mean wind data in Japanese Ocean Flux Data Sets with Use of Remote Sensing Observation (J-OFURO)-3 and to investigate its causes by comparing with in-situ data observed by moored buoys. Results reveal that the accuracy of daily-mean sea surface wind data in J-OFURO3 has been clearly improved as time goes on, and the improvement strongly depends on usage of sensors of multiple satellites. Also, we found that the improvement depends on not only the number of a satellite sensor but also on the maximum value of time intervals between two neighboring data within a day.
