Abstract

The invention provides a cross calibration method and device for the significant wave height of a wave buoy, electronic equipment and a storage medium. The method comprises the steps of acquiring historical remote sensing wave significant wave height data and historical wave significant wave height data observed by buoys of different specifications; performing space-time matching, numerical discrete averaging and matching regression on the historical remote sensing wave significant wave height data and historical wave significant wave height data observed by buoys of different specifications,and establishing a buoy significant wave height cross calibration equation; acquiring wave observation data of a to-be-calibrated wave buoy, the wave observation data being significant wave height data of waves; and correcting the wave significant wave height data through the buoy significant wave height cross calibration equation to obtain corrected buoy wave significant wave height data. By implementing the embodiment of the invention, cross calibration can be performed on significant wave height observation of buoys of different specifications, the consistency of significant wave heights ofwaves in observation data of a wave buoy is improved, and the application reliability and application value of wave observation by a wave buoy are effectively improved.

Description

technical field [0001] The present application relates to the technical fields of buoy measurement and big data processing, and in particular, relates to a cross-calibration method, device, electronic equipment and storage medium for the effective wave height of wave buoys. Background technique [0002] Observing waves through buoys is the most traditional and basic observation method for wave observation. Since the wave buoy is the most direct method of measuring waves, the wave observation of the wave buoy is considered to be the most accurate method of wave observation. As the most basic ocean observation method, wave buoys are often used as the real value of the actual wave situation, used to calibrate ocean remote sensing observations such as ocean satellites, or used as the real value to adjust the wave numerical model or as a standard To test the level of wave forecasting. But in fact, the specifications of wave buoys are not the same, and there are obvious differen...
