Automatic Diagnosis Method of Ice Mass Balance Buoy Interface

Abstract

The invention discloses an automatic diagnosis method for an ice mass balance buoy interface, relates to an ice mass balance buoy, and provides a processing method for the real-time transmission of data by the ice mass balance buoy, a time sequence interface diagnosis method for the ice mass balance buoy and a diagnosis method for the real-time interface of the ice mass balance buoy. The real-time algorithm of the ice mass balance buoy is established on the basis of a time sequence algorithm, a real-time algorithm is established by a MATLAB language script, and seven program modules are used; an upper boundary search initial position and a lower boundary search initial position used in the last Step4 iteration of the diagnosis result of a time sequence algorithm interface are used as reference search positions, Step5 carries out the correction of the initial search position of the interface of the N+1 days of the real-time algorithm according to a restriction condition, and Step6 utilizes a real-time algorithm interface result of the Nth day to calculate the positions of the upper boundary and the lower boundary of sea ice of the (N+1)th day.

Description

technical field [0001] The invention relates to an ice mass balance buoy, in particular to an automatic interface diagnosis method of an ice mass balance buoy (IMB). Background technique [0002] Ice mass balance buoys (IMBs) have begun to be widely deployed in the Arctic and Antarctic regions. Buoy data have also been used to detect ice thickness and energy balance studies of oceans and lakes with seasonal ice cover ([1] Perovich D K, Grenfell T C, Richtermenge J A, et al. Thin and thinner: Sea icemassbalance measurements during SHEBA[M ].2003). So far, the analysis of ice mass balance buoy data has been largely based on manual processing. Scholars previously interpreted past ice mass-balance buoy data by interpreting the data itself rather than using a systematic approach ([2]Richtermenge J A, Perovich D K, Elder B C, etal. Ice mass-balance buoys: a tool for measuring and attributing changes in the thickness of the Arctic sea-ice cover [J]. Annals of Glaciology, 2006, 4...

In the process of judgment, it is very likely that due to the difference in the experience of the data users, the judgment of the interface of the medium layer will be different, which will affect the objectivity of the follow-up research and the reliability of the research conclusion.

To date, there is no rapid processing procedure and automated interface diagnostic method for ice mass balance buoy data
