The FIB technique will be replaced in the near future by an Optimum Interpolation (OI) technique. The OI technique is an objective analysis methodology widely used in meteorolog-ical and oceanographic applications. It differs from the FIB technique in that it is based upon the concept that the results of the interpolation process must contain the same statistical field properties, that is, time and space statistical structure of variability, independent of the density of observations.

Learning Objective: Name the FLENUM-OCEANCEN model used to analyze program is run every 6 hours.

The upper-air analysis model is a subset of the Navy Operational Global Atmospheric Prediction System (NOGAPS). Geopotential heights, temperature, and wind are analyzed for the mandatory levels 1,000 millibars to 100 millibars.
