海气界面观测浮标现场原位校准技术研究

The Research on In-situ Calibration Technology of Air-sea Interface Observation Buoy

海气界面观测浮标可长时间、连续不断地同步收集海面气象和水文数据,是全球海气相互作用研究的重要技术之一。分析了海气浮标校准工作存在问题,提出了一种海气界面观测浮标现场原位校准技术,依托国家浅海海洋综合试验场,进行海气界面观测浮标计量校准技术研究。海试数据显示现场原位校准技术可行、过程可控、结果可信,气象和水文参数均满足《气象观测规范》和《海滨观测规范》要求,可达到陆地校准技术精度要求,研究结果为海气浮标量值溯源提供了一种新的有效途径。

The sea-air interface observation buoy can collect sea surface meteorological and hydrological data synchronously for a long time and continuously.It is one of the important technical supports for the study of global air-sea interaction.Researchers analyze the problems in the calibration of sea-air buoys,and proposes an in-situ calibration technique for sea-air interface observation buoys.Based on the National Shallow Sea Marine Comprehensive Test Field,it conducts a study on the measurement calibration technology of sea-air interface buoys.The sea trial data shows that the on-site in-situ calibration technology is feasible,the process is controllable,and the results are credible.Both the meteorological and hydrological parameters meet the requirements of《Specifications for Surface Meteorological Observation》and《The Specification for Offshore Observations》,which can meet the accuracy requirements of the land calibration technology.The traceability of the float value provides a new and effective way.
