Abstract

The invention provides a data processing method and device for a multi-source satellite altimeter, equipment and a storage medium. The data processing method comprises the steps of performing data quality control on data of a to-be-processed satellite altimeter and a Jason-3 satellite altimeter; by taking the Jason-3 satellite altimeter as a reference, performing data unification on height measurement data of the to-be-processed satellite altimeter after data quality control; by taking the Jason-3 satellite altimeter as a reference, performing orbit error correction on the height measurement data of the to-be-processed satellite altimeter after data unification; and calculating sea surface height abnormal data of each satellite altimeter according to the height measurement data after orbit error correction. In the implementation process, before the sea surface height abnormal data of each satellite altimeter is calculated, data unification and orbit error correction of the height measurement data of the satellite altimeters are performed, and the sea surface height abnormal data is calculated according to the height measurement data after orbit error correction, so that the accuracy of a sea surface height abnormal result is greatly improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular, to a data processing method, device, equipment and storage medium of a multi-source satellite altimeter. Background technique [0002] Measuring altitude by satellite altimeter has become one of the important means to study sea level change. In the prior art, the formula SLA=SSH-MSS [that is, the sea level anomaly data SLA (Sea Level Anomaly) is equal to the track sea level SSH (Sea The difference between Surface Hight) observed value and mean sea level height MSS (Mean Sea Surface)] after calculating the sea surface height anomaly data, and then carry out data unification and orbit error correction on the calculated sea surface height anomaly data, and obtain the orbit error The corrected sea surface height anomaly data, the corrected sea surface height anomaly data obtained in this way deviates greatly from the actual situation, is not accurate enough, and has l...
