Coordinated Enhanced Observing Period The Scripps Institution of Oceanography sExperimental Climate Prediction Center (ECPC) works in collaboration with NCEP to analyze and develop their global and regional atmospheric models. In particular, the ECPC is currently using both the NCEP/DOE Reanalysis II model (RII; Kanamitsu et al. 2002; Roads et al. 2002, Roads 2003) and the NCEP seasonal forecast model (SFM; Kanamitsu et al. 2002) to provide model output for CEOP (see e.g. Roads et al. 2003).
