Method for the production of mean sea surface height products based on satellite altimeter data network function interpolation

Abstract

The present invention discloses a method for the production of mean sea height products based on satellite altimeter data network function interpolation, which comprises the steps of: data preprocessing, determination of grid size and central point, grid interpolation, and refined interpolation. The method according to the present invention facilitates automatic grid segmentation on the computer, has obvious statistical characteristics, reflect the spatial distribution of the marine gravity field on the physical properties, wherein the marine gravity field is in a positive proportion to mean sea surface height, gives full consideration to the physical characteristics of sea level, and can improve mean sea height products of high accuracy and spatial resolution.

Description

technical field [0001] The invention relates to a production method, in particular to a production method of an average sea surface height product of satellite altimetry data based on network function interpolation. Background technique [0002] The mean sea level height refers to the average value of the water level in a certain period of time, and the time scale should be long enough to eliminate all physical vibrations and stabilize the mean sea level. [0003] The average sea surface height product refers to the gridded average sea surface height dataset obtained by processing multi-source satellite altimetry data. [0004] The high-precision and high-resolution average sea surface height data is an important basis for the study of ocean dynamic environment changes, and is an important supporting data for the study of global sea level changes and climate changes. Explanation of environmental changes. [0005] With the continuous launch of altimetry satellites and the a...
