NGGPS Implementation

The National Weather Service will design, develop, and implement a global prediction system to address growing service demands, and increase the accuracy of weather forecasts out to 30 days. The goal is to expand and accelerate critical weather forecasting research to operation (R2O) through accelerated development and implementation of current global weather prediction models, improved data assimilation techniques, and improved software architecture and system engineering. Over the next five years, contributions from a wide sector of the numerical weather prediction community including NCEP, NOAA and other agency laboratories and universities, will be incorporated into an operational system to deliver a Next Generation Global Prediction System (NGGPS) that meets the evolving national prediction requirements.
