NOAA completes upgrade to weather and climate supercomputer system


Recommended Posts



  • Upgrades to the U.S. Global Forecast System will make it higher-resolution. The model's horizontal resolution will improve to nine kilometers, compared to 13 in the current version. This upgrade will help smaller-scale features to be seen and simulated, improving model accuracy and overall model performance.
  • A new Rapid Refresh Forecast System, which will allow for larger ensembles with more data included, providing a measure of certainty in a particular forecast that can lead to better decision-making. These updates also allow for more advanced high-resolution data-assimilation techniques.
  • Upgrades to the Global Ensemble Forecast System, which will more accurately capture what is known as radiatively active aerosols to better model emissions such as wildfire smoke, dust and fog. 
  • Expansion in compute power and storage, which will provide operational capacity to implement research and development advancements made through NOAA’s Earth Prediction Innovation Center
