abstract: The North American Multi-Model Ensemble (NMME) is a multi-model seasonal forecasting system consisting of coupled models from North American modeling centers. The contributing modeling centers are NOAA's National Centers for Environmental Prediction (NCEP), NOAA's Geophysical Fluid Dynamics Laboratory (GFDL), NASA's Goddard Space Flight Center (GSFC), Environment Canada’s Centre for Climate Modeling and Analysis (CCCma), and the National Center for Atmospheric Research (NCAR). The models include the Climate Forecast System model version 2 (CFSv2-2011), the Forecast-oriented Low Ocean Resolution model using parameter set B (FLORB-01), the Goddard Earth Observing System Model version 5 (GEOS-5), the Canadian Coupled Climate Model versions 3 and 4 (CanCM3, CanCM4), the Community Earth System Model version 1 (CESM1) and the Community Climate System Model version 4 (CCSM4). It contains global, 12-month daily forecasts of key variables from the participating models at a 1-degree latitude by 1-degree longitude spatial resolution. The model variables are liquid water equivalent precipitation rate, 2-meter air temperature, maximum and minimum 2-meter air temperatures, zonal and meridional surface stress, air pressure at sea level, specific humidity at 850 hPa, zonal and meridional wind at 850 hPa, zonal and meridional wind at 200 hPa, geopotential height at 500 hPa, net solar flux at surface and net longwave flux at top of model. The data file format is netCDF.
purpose: Several studies have found that the multi-model ensemble (MME) approach has proven extremely effective at quantifying prediction uncertainty due to uncertainty in model formulation, and has proven to produce better prediction quality (on average) than a single model ensemble.
