To better support the U.S. Air Force (USAF) world-wide mission set an operational transition from regional modeling based on the Weather Research and Forecasting (WRF) model to global modeling based on the Global Air-Land Weather Exploitation Model (GALWEM) was completed in Oct 2015.  The GALWEM emerged from an operational partnership between the U.K Met Office (UKMO) and the Air Force Weather enterprise started in 2010 and represents a unique instantiation of the UKMO Unified Model.  Work is underway to implement a global ensemble system using GALWEM by mid-2017.  The USAF expects to generate up to 40 ensemble members each day (10 member x 4 cycles per day).  The GALWEM ensemble output will be made available for inclusion into the National Unified Ensemble (NUE) managed by the Earth System Prediction Capability (ESPC) program.
