• Unified Forecast System Research-to-Operations (UFS-R2O) Project Proposal

  This is a proposal to coordinate a large community of researchers, both inside and outside the National Oceanic and Atmospheric Administration (NOAA), to improve numerical weather and climate prediction by further developing and analyzing the Unified Forecast System (UFS), with the ultimate goal of improving the skill of NOAA’s operational forecast models

• NOAA Upgrades the U.S. Global Forecast Model

  On June 12, 2019, NOAA's Global Forecast System (GFS) had a significant upgrade to include the new dynamical core. This upgrade will drive global numerical weather prediction into the future with improved forecasts. Read more about the upgrade here.

• NCAR-NOAA Memorandum of Agreement (MOA) for Co-development of a Common Modeling Infrastructure (January 30, 2019)

  This Memorandum of Agreement helps establish a new partnership to design a common modeling infrastructure that will be transparent and easy to access and use by public and private researchers, including academia and industry. By leveraging efficiencies and synergies, reducing duplication of effort, and creating shared model repositories, future research advances will more quickly benefit the public through better weather and climate forecasts.

• More Accuracy with less precision - assessing information content for reliable weather and climate prediction by Tim Palmer, (Royal Society Research Professor, University of Oxford)

  The reasons for stochastic parmeterisation are reviewed.  From this, we conclude that conventional 64-bit floating-point representations in NWP and climate models are, for the most part, unnecessary and energetically profligate.  It is argued that a new start is needed for the development of Earth-System Models, based on the primacy of information content.
