GFDL Prediction Models

SPEAR (Seamless System for Prediction and EArth System Research)

SPEAR was developed as a next generation GFDL modeling system for seasonal to multidecadal prediction and projection. In early 2021, SPEAR real-time seasonal predictions will be made available as part of the North American Multi-Model Ensemble (NMME) and SPEAR decadal predictions will be made available as part of an international decadal prediction program through the UK Met Office (decadal forecast). Additional data from the SPEAR large ensemble, described in Delworth et al. (2020) will also be made available through the GFDL Data Portal in March 2021 (note: subset data from published papers to date is available at publication with details in each paper). Previously, the GFDL CM2.1 and FLOR models were used for real-time seasonal-to-decadal prediction and research.
