AB: We performed metrics analysis of the ENLIL heliospheric cone model by studying halo CME propagation and evolution to the L1 point and comparing the result to ACE observations. A cone model-based halo CME representation is inserted into the combined WSA-ENLIL or MAS-ENLIL model. We simulated a number of geomagnetic storms and series of events selected by community campaigns, including the October 2003 Halloween Storm CME and the recent fall AGU storm on December 15, 2006. We will present a set of such simulations and we will analyze the quality of the match between different solar wind parameters in the model and in the observations. In addition, we will study whether there are any systematic time lags between model outputs and observations by ACE. We also describe real-time setup for the ENLIL cone model to trigger CME alert capability at the Community Coordinated Modeling Center.
