Abstract

The invention discloses a buoy surge wave height observation data error evaluation method, system and device and a medium, and relates to the technical field of buoy measurement and big data processing. Establishing a triple matching data set of radar satellite observation data and sea wave numerical mode post-reporting data; the radar satellite observation data comprises synthetic aperture radar remote sensing sea wave data and real aperture radar remote sensing sea wave data; estimating the precision difference between the buoy observation data and the wave numerical pattern post-reporting data according to the double matching data set, estimating the error of the wave numerical pattern post-reporting data relative to the theoretical true value according to the triple matching data set, and estimating the error of the buoy observation data relative to the theoretical true value by using the precision difference and the error. And the consistency of wave buoy surge wave height observation is improved, so that the buoy observation data application effect is effectively improved.

Description

technical field [0001] The invention relates to the technical fields of buoy measurement and big data processing, and in particular to a method, system, electronic device and computer-readable storage medium for evaluating the error of buoy swell wave height observation data. Background technique [0002] Swell is a common ocean phenomenon, mainly refers to the long-period sea surface waves left over after the local wind speed weakens or the wind direction changes, or generated by the storm sea area and propagated over long distances. Accurate observation of swell wave height has important scientific research significance and engineering practice significance for the research of momentum exchange in the air-sea boundary layer and the early warning and monitoring of ocean swell. [0003] Wave buoy (hereinafter referred to as buoy) is one of the main methods for long-term fixed-point on-site observation of swell. Because of its high reliability and accurate measurement, it is ...
