North American Multi-Model Ensemble

The North American Multi-Model Ensemble (NMME) is a multi-model, seasonal forecasting system consisting of coupled models from North American modeling centers including NOAA's National Centers for Environmental Prediction (NCEP), NOAA's Geophysical Fluid Dynamics Laboratory (GFDL), the National Center for Atmospheric Research (NCAR), NASA's Goddard Space Flight Center (GSFC), and Canada’s Centre for Climate Modelling and Analysis (CCCma). The models include CCSM4, CESM1, CFSV2-2011, CanCM3, CanCM4, FLORB-01 and GEOS-5.

This collection of NMME data contains global, 12-month daily forecasts (containing ten realizations) of 13 key variables from the participating models at a 1º by 1º spatial resolution. Variables include the following, by model and variable name (variables not available are denoted by "N/A").
