On-Scene Analysis/Forecast System
Abstract
LONG-TERM GOAL. Develop and demonstrate an end-to-end, on-scene analysis/forecast system for real-time data fusion, analysis, and forecasting. This system will be used to produce tactical atmospheric parameters that affect weapon and sensor systems and will be designed to use a local area network interfaced to automated instruments, a modern database, and supporting software. OBJECTIVES. Develop the framework for an analysis, nowcast, and short-term forecast system that can be used at on scene locations. This development will include optimal objective analysis methods that blend all observations and dynamical constraints into a 3-dimensional depiction of the atmosphere; methods to include new data sources (e.g., in-situ, remotely sensed observations) into existing analysis methods; quality control methods for on-scene observations to insure time and space continuity; initialization procedures to reduce high-frequency oscillations resulting from initial imbalances of analyzed data; a procedure for flexible and efficient execution of inner grids (e.g., starting time, location); and a hierarchy of physical parameterizations that allow a choice between computational time and sophistication. The performance of the system will be evaluated, and studies will be performed to determine the impact of simplified model physics and/or code optimization to meet time constraints.
