Global Data-processing and Forecasting System

Enabling worldwide use of timely, reliable and accurate Numerical Weather Prediction (NWP) products and services in all time-scales for applications related to weather, climate, water and environment.

The Global Data-processing and Forecasting System (GDPFS) is an international mechanism that coordinates Member capacities to prepare and make meteorological analyses and forecast products available to all Members, enabling delivery of harmonized services. These products are generated based on observational data and cutting-edge science and technology. The 2021 Extraordinary World Meteorological Congress approved the WMO Unified Policy for the International Exchange of Earth System Data. The use of more and better assimilated observational data, especially those from Global Basic Observation Network (GBON), enables designated GDPFS Centres to produce higher quality and more accurate analysis and prediction products, which are then made available to all Members.

The GDPFS is organized as a network of Global, Regional and National Centres. Information about designated GDPFS Centres and their products is available on the GDPFS Web Portal (Please click the screenshot or the link followed to access the GDPFS Web Portal).
