The North American Multi-Model Ensemble (NMME) is a seasonal forecasting system that consists of multiple coupled models from North American modeling centers. NCEI provides access to data for global, 12-month forecasts of 13 key variables. NMME data is daily or 6-hourly with a 1º by 1º spatial resolution. Most NMME datasets have 10 realizations for each variable.
Access Methods
As of March 2018, data for CFSv2 and CCSM4 are accessible through the access links below. The other model datasets will be accessible once they arrive in the NCEI archive.
