Test and evaluation of objective mapping applied to oceanographic data from GIN Sea '86

Abstract

Sonar performance, and hence the capability to detect and track submarines, requires a knowledge of the environmental conditionsto serve as input data for analysis and modelling applications. Since most of the oceanographic observations are made at irregularly distributedlocations, it is necessary to assign estimates of physical variables to points on a regular grid. An ideal procedure has to filter the disturbances inherent in the data, minimize observational errors, and provide the 'best' solution in regions lacking data.
