The EMC tracker code is run for TC-track calculations with the real time raw forecast data from NCEP, ECMWF, Navy and Canadian Ensemble Forecasts. For the UK MetOffice ensemble, we receive the TC track forecast directly from their server. This work is sponsored by HFIP/NUOPC Project. Many thanks to Tim Marchok (GFDL), Guang Ping Lou (EMC) and all other colleagues in EMC Ensemble Team and HWRF Team for their lots of comments and suggestions.
