Embodiment Construction

[0027] The implementation of the sea surface chlorophyll path simulation technology of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] During the research, it was found that the advective transport of chlorophyll on the sea surface is mainly driven by the upper ocean, especially the ocean surface currents, and the advective movement of the chlorophyll concentration on the sea surface can be well represented by using the virtual drift float. The Lagrangian trajectory of the buoy is used to simulate and predict the transportation path of the concentration of chlorophyll on the sea surface.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embod...

Abstract

The invention provides a sea surface chlorophyll transmission path simulation method based on satellite observation data. Sea surface chlorophyll concentration obtained by remote sensing observation of a satellite-borne sensor is used as an initial source point; based on a sea surface flow field based on satellite observation and numerical simulation, random disturbance caused by turbulence is considered; the transmission distance of chlorophyll is subjected to transmission distance continuous simulation based on a Monte Carlo method, and the horizontal transport vector time sequence of chlorophyll in a preset target area in a preset period is determined, so that reliable simulation of a sea surface chlorophyll concentration transmission path is realized, and chlorophyll path simulation prediction can be realized quickly, accurately and reliably.

Description

technical field [0001] The invention relates to the fields of marine technology and satellite remote sensing technology, in particular to a method and device for simulating a sea surface chlorophyll horizontal transport path. Background technique [0002] Ocean remote sensing (ocean remote sensing) uses sensors to conduct long-distance non-contact observations of the ocean to obtain images or data of ocean landscapes and ocean elements. The ocean continuously radiates electromagnetic wave energy to the environment, and the sea surface also reflects or scatters electromagnetic wave energy from the sun and artificial radiation sources (such as radar), so some special sensors can be designed and loaded on artificial satellites, spacecraft, aircraft, rockets, etc. The electromagnetic radiation energy is received and recorded on working platforms carried by balloons and balloons, and then transmitted, processed and processed to obtain ocean images or data.
