在海气通量的定量评估中，船上直接测量的涡动通量是必不可少的。本文作者研制了一种新的实时自动涡流通量测量系统，并已在JAMSTEC的米拉伊号R/V上作为常规测量系统运行。与我们以前的系统相比，简化了船舶运动校正方案，并引入了实时涡通量数据处理系统作为自动化系统。作为世界上连续运行的真实的实时涡流通量船，这是一个独特的系统。通量数据集的质量控制至关重要，因为数据是连续收集的，包括在不利条件下。应用了初步质量控制，结果显示与散装参数相比的合理值。基于详细的质量控制，可以在各种条件下参数化本体传递系数。
On-board direct eddy flux measurement is essential in the quantitative air-sea flux evaluation as sea truth flux. Present authors have developed a new real-time automated eddy flux system and it is operating as a routine measurement on R/V MIRAI, JAMSTEC. As compared to our previous system, ship motion correction scheme is simplified and real-time eddy flux data processing system is introduced as the automated system. As a continuously operating real time eddy flux ship in the world, this is a unique system.The quality control of the flux datasets is essential as the data is collected continuously including during unfavorable conditions. Preliminary quality control was applied and the results show the reasonable values as compared to the bulk parameters. Based on the detailed quality control, the bulk transfer coefficients can be parameterized in various conditions.
