Purpose of FAA Model Development and Enhancement (MDE) Team Improve accuracy of hourly updated weather models, needed especially for increasing aviation requirements. NOAA Research (GSD) leads and coordinates MDE project with other labs -- NCAR, NOAA operations (NWS, NCEP), universities, MIT/Lincoln Labs Steady improvement in weather model guidance is critical to meet future requirements for National Air Space in NextGen era.
