An Advanced Framework for Battlespace Environment Data Assimilation
Abstract
Battlespace environment data assimilation is a key element of the DoD's strategic plan to ensure information superiority and battlespace dominance in the 21st century. It is used to provide all the necessary initial conditions for making atmospheric/ oceanic forecasts and to produce the common operational picture required by the warfighter. The Navy's current operational data assimilation systems are three-dimensional (3D) and provide the warfighter with a snapshot of the battlespace environment at a single point in time, several times a day. To provide the warfighter with a continuous picture of the battlespace environment over the time window of the observations used to generate the initial conditions, a highly advanced and efficient four-dimensional (4D) data assimilation algorithm suitable for both atmospheric and oceanic applications is essential. To meet the warfighter's requirement in the 21st century, scientists at NRL-Monterey have recently developed an advanced framework for battlespace environment data assimilation, called NAVDAS-AR: NRL Atmospheric Variational Data Assimilation System - Accelerated Representer. Here we give a brief description of the current operational system, then describe the NAVDAS-AR framework and its current and future applications.
