Supporting the U.S. Army Test and Evaluation Command (ATEC)

Benefits

Knowledge of detailed predicted and actual weather conditions saves the Army millions of dollars annually. NCAR has since adapted the system and created derivative technologies for use by other organizations.

Challenge

Developing an advanced high-resolution numerical weather prediction (NWP) system that analyzes current weather and makes detailed predictions of weather over the next several days, specifically for the U.S. Army Test and Evaluation Command (ATEC).

Solution

Four-Dimensional Weather (4DWX) System - Range-Scale Modeling, Four-Dimensional Weather (4DWX) System, 4DWX TAMDAR Evaluation

Four-Dimensional (4DWX) System – 4DWX is the product of more than one and a half decades of research and development sponsored largely by the U.S. Army Test and Evaluation Command. This technology is accredited for operational use at seven Army Test Ranges. The system utilizes advanced numerical weather prediction, data assimilation, probabilistic methods, nowcasting, and plume dispersion technologies.
