Quality Control Algorithms for Ocean Temperature Data
Abstract
The Fleet Numerical Oceanography Center (FNOC) provides daily analyses of the three-dimensional ocean thermal structure both of the fleet and to regional oceanography centers around the world. These analyses are performed on both hemispheric and regional scale grids, with resolutions as fine as 20 km in some areas. The Remote Sensing Branch of the Naval Ocean Research and Development Activity (NORDA) has been involved in assessing the impact of multichannel sea surface temperatures (MCSSTs) on these ocean thermal analyses. Specifically, NORDA has worked closely with FNOC in developing the Optimum Thermal Interpolation System (OTIS). NORDA'S primary interest was to assure that the MCSSTs were properly utilized to detect and analyse mesoscale ocean fronts and eddies, with particular attention paid to how the MCSSTs were assimilated with other types of data. Through this joint effort, FNOC has successfully implemented OTIS as the operational ocean thermal analysis system for the global analysis and the Gulf Stream regional analysis. In addition to processing and assimilating data from various sources, OTIS includes quality control algorithms to automatically make decisions about the quality of the observations and to ignore data that are apparently erroneous.
